The US Justice Department and Federal Trade Commission reportedly plan investigations into whether Nvidia, Microsoft, and OpenAI are snuffing out competition in artificial intelligence technology.

The agencies struck a deal on how to divide up the investigations, The New York Times reported yesterday. Under this deal, the Justice Department will take the lead role in investigating Nvidia’s behavior while the FTC will take the lead in investigating Microsoft and OpenAI.

The agencies’ agreement “allows them to proceed with antitrust investigations into the dominant roles that Microsoft, OpenAI, and Nvidia play in the artificial intelligence industry, in the strongest sign of how regulatory scrutiny into the powerful technology has escalated,” the NYT wrote.

One potential area of investigation is Nvidia’s chip dominance, “including how the company’s software locks customers into using its chips, as well as how Nvidia distributes those chips to customers,” the report said. An Nvidia spokesperson declined to comment when contacted by Ars today.

High-end GPUs are “scarce,” antitrust chief says

Jonathan Kanter, the assistant attorney general in charge of the DOJ’s antitrust division, discussed the agency’s plans in an interview with the Financial Times this week. Kanter said the DOJ is examining “monopoly choke points and the competitive landscape” in AI.

The DOJ’s examination of the sector encompasses “everything from computing power and the data used to train large language models, to cloud service providers, engineering talent and access to essential hardware such as graphics processing unit chips,” the FT wrote.

Kanter said regulators are worried that AI is “at the high-water mark of competition, not the floor” and want to take action before smaller competitors are shut out of the market. The GPUs needed to train large language models are a “scarce resource,” he was quoted as saying.

“Sometimes the most meaningful intervention is when the intervention is in real time,” Kanter told the Financial Times. “The beauty of that is you can be less invasive.”

Microsoft deal scrutinized

The FTC is scrutinizing Microsoft over a March 2024 move in which it hired the CEO of artificial intelligence startup Inflection and most of the company’s staff and paid Inflection $650 million as part of a licensing deal to resell its technology. The FTC is investigating whether Microsoft structured the deal “to avoid a government antitrust review of the transaction,” The Wall Street Journal reported today.

“Companies are required to report acquisitions valued at more than $119 million to federal antitrust-enforcement agencies, which have the option to investigate a deal’s impact on competition,” the WSJ wrote. The FTC reportedly sent subpoenas to Microsoft and Inflection in an attempt “to determine whether Microsoft crafted a deal that would give it control of Inflection but also dodge FTC review of the transaction.”

Inflection built a large language model and a chatbot called Pi. Former Inflection employees are now working on Microsoft’s Copilot chatbot.

“If the agency finds that Microsoft should have reported and sought government review of its deal with Inflection, the FTC could bring an enforcement action against Microsoft,” the WSJ report said. “Officials could ask a court to fine Microsoft and suspend the transaction while the FTC conducts a full-scale investigation of the deal’s impact on competition.”

Microsoft told the WSJ that it complied with antitrust laws, that Inflection continues to operate independently, and that the deals gave Microsoft “the opportunity to recruit individuals at Inflection AI and build a team capable of accelerating Microsoft Copilot.”

OpenAI

Microsoft’s investment in OpenAI has also faced regulatory scrutiny, particularly in Europe. Microsoft has a profit-sharing agreement with OpenAI.

Microsoft President Brad Smith defended the partnership in comments to the Financial Times this week. “The partnerships that we’re pursuing have demonstrably added competition to the marketplace,” Smith was quoted as saying. “I might argue that Microsoft’s partnership with OpenAI has created this new AI market,” and that OpenAI “would not have been able to train or deploy its models” without Microsoft’s help, he said.

We contacted OpenAI today and will update this article if it provides any comment.

In January 2024, the FTC launched an inquiry into AI-related investments and partnerships involving Alphabet, Amazon, Anthropic, Microsoft, and OpenAI.

The FTC also started a separate investigation into OpenAI last year. A civil investigative demand sent to OpenAI focused on potentially unfair or deceptive privacy and data security practices, and “risks of harm to consumers, including reputational harm.” The probe focused partly on “generation of harmful or misleading content.”

Nvidia emails: Elon Musk diverting Tesla GPUs to his other companies

why not just make cars? —

The Tesla CEO is accused of diverting resources from the company again.

Tesla

Elon Musk is yet again being accused of diverting Tesla resources to his other companies. This time, it’s high-end H100 GPU clusters from Nvidia. CNBC’s Lora Kolodny reports that while Tesla ordered these pricey computers, emails from Nvidia staff show that Musk instead redirected 12,000 GPUs to be delivered to his social media company X.

It’s almost unheard of for a profitable automaker to pivot its business into another sector, but that appears to be the plan at Tesla as Musk continues to say that the electric car company is instead destined to be an AI and robotics firm instead.

Does Tesla make cars or AI?

That explains why Musk told investors in April that Tesla had spent $1 billion on GPUs in the first three months of this year, almost as much as it spent on R&D, despite being desperate for new models to add to what is now an old and very limited product lineup that is suffering rapidly declining sales in the US and China.

Despite increasing federal scrutiny here in the US, Tesla has reduced the price of its controversial “full-self driving” assist, and the automaker is said to be close to rolling out the feature in China. (Questions remain about how many Chinese Teslas would be able to utilize this feature given that a critical chip was left out of 1.2 million cars built there during the chip shortage.)

Perfecting this driver assist would be very valuable to Tesla, which offers FSD as a monthly subscription as an alternative to a one-off payment. The profit margins for subscription software services vastly outstrip the margins Tesla can make selling physical cars, which dropped to just 5.5 percent for Q1 2024. And Tesla says that massive GPU clusters are needed to develop FSD’s software.

Isn’t Tesla desperate for Nvidia GPUs?

Tesla has been developing its own in-house supercomputer for AI, called Dojo. But Musk has previously said that computer could be redundant if Tesla could source more H100s. “If they could deliver us enough GPUs, we might not need Dojo, but they can’t because they’ve got so many customers,” Musk said during a July 2023 investor day.

Which makes his decision to have his other companies jump all the more notable. In December, an internal Nvidia memo seen by CNBC said, “Elon prioritizing X H100 GPU cluster deployment at X versus Tesla by redirecting 12k of shipped H100 GPUs originally slated for Tesla to X instead. In exchange, original X orders of 12k H100 slated for Jan and June to be redirected to Tesla.”

X and the affiliated xAi are developing generative AI products like large language models.

Not the first time

This is not the first time that Musk has been accused of diverting resources (and his time) from publicly held Tesla to his other privately owned enterprises. In December 2022, US Sen. Elizabeth Warren (D-Mass.) wrote to Tesla asking Tesla to explain whether Musk was diverting Tesla resources to X (then called Twitter):

This use of Tesla employees raises obvious questions about whether Mr. Musk is appropriating resources from a publicly traded firm, Tesla, to benefit his own private company, Twitter. This, of course, would violate Mr. Musk’s legal duty of loyalty to Tesla and trigger questions about the Tesla Board’s responsibility to prevent such actions, and may also run afoul other “anti-tunneling rules that aim to prevent corporate insiders from extracting resources from their firms.”

Musk giving time meant (and compensated) for by Tesla to SpaceX, X, and his other ventures was also highlighted as a problem by the plaintiffs in a successful lawsuit to overturn a $56 billion stock compensation package.

And last summer, the US Department of Justice opened an investigation into whether Musk used Tesla resources to build a mansion for the CEO in Texas; the probe has since expanded to cover behavior stretching back to 2017.

These latest accusations of misuse of Tesla resources come at a time when Musk is asking shareholders to reapprove what is now a $46 billion stock compensation plan.

Nvidia jumps ahead of itself and reveals next-gen “Rubin” AI chips in keynote tease

Swing beat —

“I’m not sure yet whether I’m going to regret this,” says CEO Jensen Huang at Computex 2024.

Nvidia's CEO Jensen Huang delivers his keystone speech ahead of Computex 2024 in Taipei on June 2, 2024.

Enlarge / Nvidia’s CEO Jensen Huang delivers his keystone speech ahead of Computex 2024 in Taipei on June 2, 2024.

On Sunday, Nvidia CEO Jensen Huang reached beyond Blackwell and revealed the company’s next-generation AI-accelerating GPU platform during his keynote at Computex 2024 in Taiwan. Huang also detailed plans for an annual tick-tock-style upgrade cycle of its AI acceleration platforms, mentioning an upcoming Blackwell Ultra chip slated for 2025 and a subsequent platform called “Rubin” set for 2026.

Nvidia’s data center GPUs currently power a large majority of cloud-based AI models, such as ChatGPT, in both development (training) and deployment (inference) phases, and investors are keeping a close watch on the company, with expectations to keep that run going.

During the keynote, Huang seemed somewhat hesitant to make the Rubin announcement, perhaps wary of invoking the so-called Osborne effect, whereby a company’s premature announcement of the next iteration of a tech product eats into the current iteration’s sales. “This is the very first time that this next click as been made,” Huang said, holding up his presentation remote just before the Rubin announcement. “And I’m not sure yet whether I’m going to regret this or not.”

Nvidia Keynote at Computex 2023.

The Rubin AI platform, expected in 2026, will use HBM4 (a new form of high-bandwidth memory) and NVLink 6 Switch, operating at 3,600GBps. Following that launch, Nvidia will release a tick-tock iteration called “Rubin Ultra.” While Huang did not provide extensive specifications for the upcoming products, he promised cost and energy savings related to the new chipsets.

During the keynote, Huang also introduced a new ARM-based CPU called “Vera,” which will be featured on a new accelerator board called “Vera Rubin,” alongside one of the Rubin GPUs.

Much like Nvidia’s Grace Hopper architecture, which combines a “Grace” CPU and a “Hopper” GPU to pay tribute to the pioneering computer scientist of the same name, Vera Rubin refers to Vera Florence Cooper Rubin (1928–2016), an American astronomer who made discoveries in the field of deep space astronomy. She is best known for her pioneering work on galaxy rotation rates, which provided strong evidence for the existence of dark matter.

A calculated risk

Nvidia CEO Jensen Huang reveals the

Enlarge / Nvidia CEO Jensen Huang reveals the “Rubin” AI platform for the first time during his keynote at Computex 2024 on June 2, 2024.

Nvidia’s reveal of Rubin is not a surprise in the sense that most big tech companies are continuously working on follow-up products well in advance of release, but it’s notable because it comes just three months after the company revealed Blackwell, which is barely out of the gate and not yet widely shipping.

At the moment, the company seems to be comfortable leapfrogging itself with new announcements and catching up later; Nvidia just announced that its GH200 Grace Hopper “Superchip,” unveiled one year ago at Computex 2023, is now in full production.

With Nvidia stock rising and the company possessing an estimated 70–95 percent of the data center GPU market share, the Rubin reveal is a calculated risk that seems to come from a place of confidence. That confidence could turn out to be misplaced if a so-called “AI bubble” pops or if Nvidia misjudges the capabilities of its competitors. The announcement may also stem from pressure to continue Nvidia’s astronomical growth in market cap with nonstop promises of improving technology.

Accordingly, Huang has been eager to showcase the company’s plans to continue pushing silicon fabrication tech to its limits and widely broadcast that Nvidia plans to keep releasing new AI chips at a steady cadence.

“Our company has a one-year rhythm. Our basic philosophy is very simple: build the entire data center scale, disaggregate and sell to you parts on a one-year rhythm, and we push everything to technology limits,” Huang said during Sunday’s Computex keynote.

Despite Nvidia’s recent market performance, the company’s run may not continue indefinitely. With ample money pouring into the data center AI space, Nvidia isn’t alone in developing accelerator chips. Competitors like AMD (with the Instinct series) and Intel (with Guadi 3) also want to win a slice of the data center GPU market away from Nvidia’s current command of the AI-accelerator space. And OpenAI’s Sam Altman is trying to encourage diversified production of GPU hardware that will power the company’s next generation of AI models in the years ahead.

geforce-now-has-made-steam-deck-streaming-much-easier-than-it-used-to-be

GeForce Now has made Steam Deck streaming much easier than it used to be

Easy, but we’re talking Linux easy —

Ask someone who previously did it the DIY way.

Fallout 4 running on a Steam Deck through GeForce Now

Enlarge / Streaming Fallout 4 from GeForce Now might seem unnecessary, unless you know how running it natively has been going.

Kevin Purdy

The Steam Deck is a Linux computer. There is, technically, very little you cannot get running on it, given enough knowledge, time, and patience. That said, it’s never a bad thing when someone has done all the work for you, leaving you to focus on what matters: sneaking game time on the couch.

GeForce Now, Nvidia’s game-streaming service that uses your own PC gaming libraries, has made it easier for Steam Deck owners to get its service set up on their Deck. On the service’s Download page, there is now a section for Gaming Handheld Devices. Most of the device links provide the service’s Windows installer, since devices like the ROG Ally and Lenovo Legion Go run Windows. Some note that GeForce Now is already installed on devices like the Razer Edge and Logitech G Cloud.

But Steam Deck types are special. We get a Unix-style executable script, a folder with all the necessary Steam icon image assets, and a README.md file.

It has technically been possible all this time, if a Deck owner was willing to fiddle about with installing Chrome in desktop mode, tweaking a half-dozen Steam settings, and then navigating the GeForce Now site with a trackpad. GeForce Now’s script, once you download it from a browser in the Deck’s desktop mode, does a few things:

  • Installs the Google Chrome browser through the Deck’s built-in Flatpak support
  • Adjusts Chrome’s settings to allow for gamepad support in the browser
  • Sets up GeForce Now in Steam with proper command line options and icons for every window.

That last bit about the icons may seem small, but it’s a pain in the butt to find properly sized images for the many different kinds of images Steam can show for a game in your library when selected, having recently played, and so on. As for the script itself, it worked fine, even with me having previously installed Chrome and created a different Steam shortcut. I got a notice on first launch that Chrome couldn’t update, so I was missing out on all its “new features,” but that could likely be unrelated.

I was almost disappointed that GeForce Now's script just quietly worked and then asked me to head back into Gaming Mode. Too easy!

Kevin Purdy

GeForce Now isn’t for everyone, and certainly not for every Steam Deck owner. Because the standard Steam Deck LCD screen only goes to 800p and 60 Hz, paying for a rig running in a remote data center to power your high-resolution, impressive-looking game doesn’t always make sense. With the advent of the Steam Deck OLED, however, the games look a lot brighter and more colorful and run up to 90 Hz. You also get a lot more battery life from streaming than you do from local hardware, which is still pretty much the same as it was with the LCD model.

GeForce Now also offers a free membership option and $4 “day passes” to test if your Wi-Fi (or docked Ethernet) connection would make a $10/month Priority or $20/month Ultimate membership worthwhile (both with cheaper pre-paid prices). The service has in recent months been adding games from Game Pass subscriptions and Microsoft Store purchases, Blizzard (i.e., Battle.net), and a lot of same-day Steam launch titles.

If you’re already intrigued by GeForce Now for your other screens and were wondering if it could fly on a Steam Deck, now it does, and it’s only about 10 percent as painful. Whether that’s more or less painful than buying your own GPU and running your own Deck streaming is another matter.

Critics question tech-heavy lineup of new Homeland Security AI safety board

Adventures in 21st century regulation —

CEO-heavy board to tackle elusive AI safety concept and apply it to US infrastructure.

A modified photo of a 1956 scientist carefully bottling

On Friday, the US Department of Homeland Security announced the formation of an Artificial Intelligence Safety and Security Board that consists of 22 members pulled from the tech industry, government, academia, and civil rights organizations. But given the nebulous nature of the term “AI,” which can apply to a broad spectrum of computer technology, it’s unclear if this group will even be able to agree on what exactly they are safeguarding us from.

President Biden directed DHS Secretary Alejandro Mayorkas to establish the board, which will meet for the first time in early May and subsequently on a quarterly basis.

The fundamental assumption posed by the board’s existence, and reflected in Biden’s AI executive order from October, is that AI is an inherently risky technology and that American citizens and businesses need to be protected from its misuse. Along those lines, the goal of the group is to help guard against foreign adversaries using AI to disrupt US infrastructure; develop recommendations to ensure the safe adoption of AI tech into transportation, energy, and Internet services; foster cross-sector collaboration between government and businesses; and create a forum where AI leaders to share information on AI security risks with the DHS.

It’s worth noting that the ill-defined nature of the term “Artificial Intelligence” does the new board no favors regarding scope and focus. AI can mean many different things: It can power a chatbot, fly an airplane, control the ghosts in Pac-Man, regulate the temperature of a nuclear reactor, or play a great game of chess. It can be all those things and more, and since many of those applications of AI work very differently, there’s no guarantee any two people on the board will be thinking about the same type of AI.

This confusion is reflected in the quotes provided by the DHS press release from new board members, some of whom are already talking about different types of AI. While OpenAI, Microsoft, and Anthropic are monetizing generative AI systems like ChatGPT based on large language models (LLMs), Ed Bastian, the CEO of Delta Air Lines, refers to entirely different classes of machine learning when he says, “By driving innovative tools like crew resourcing and turbulence prediction, AI is already making significant contributions to the reliability of our nation’s air travel system.”

So, defining the scope of what AI exactly means—and which applications of AI are new or dangerous—might be one of the key challenges for the new board.

A roundtable of Big Tech CEOs attracts criticism

For the inaugural meeting of the AI Safety and Security Board, the DHS selected a tech industry-heavy group, populated with CEOs of four major AI vendors (Sam Altman of OpenAI, Satya Nadella of Microsoft, Sundar Pichai of Alphabet, and Dario Amodei of Anthopic), CEO Jensen Huang of top AI chipmaker Nvidia, and representatives from other major tech companies like IBM, Adobe, Amazon, Cisco, and AMD. There are also reps from big aerospace and aviation: Northrop Grumman and Delta Air Lines.

Upon reading the announcement, some critics took issue with the board composition. On LinkedIn, founder of The Distributed AI Research Institute (DAIR) Timnit Gebru especially criticized OpenAI’s presence on the board and wrote, “I’ve now seen the full list and it is hilarious. Foxes guarding the hen house is an understatement.”

Home Assistant has a new foundation and a goal to become a consumer brand

An Open Home stuffed full of code —

Can a non-profit foundation get Home Assistant to the point of Home Depot boxes?

Open Home Foundation logo on a multicolor background

Open Home Foundation

Home Assistant, until recently, has been a wide-ranging and hard-to-define project.

The open smart home platform is an open source OS you can run anywhere that aims to connect all your devices together. But it’s also bespoke Raspberry Pi hardware, in Yellow and Green. It’s entirely free, but it also receives funding through a private cloud services company, Nabu Casa. It contains tiny board project ESPHome and other inter-connected bits. It has wide-ranging voice assistant ambitions, but it doesn’t want to be Alexa or Google Assistant. Home Assistant is a lot.

After an announcement this weekend, however, Home Assistant’s shape is a bit easier to draw out. All of the project’s ambitions now fall under the Open Home Foundation, a non-profit organization that now contains Home Assistant and more than 240 related bits. Its mission statement is refreshing, and refreshingly honest about the state of modern open source projects.

The three pillars of the Open Home Foundation.

The three pillars of the Open Home Foundation.

Open Home Foundation

“We’ve done this to create a bulwark against surveillance capitalism, the risk of buyout, and open-source projects becoming abandonware,” the Open Home Foundation states in a press release. “To an extent, this protection extends even against our future selves—so that smart home users can continue to benefit for years, if not decades. No matter what comes.” Along with keeping Home Assistant funded and secure from buy-outs or mission creep, the foundation intends to help fund and collaborate with external projects crucial to Home Assistant, like Z-Wave JS and Zigbee2MQTT.

My favorite video.

Home Assistant’s ambitions don’t stop with money and board seats, though. They aim to “be an active political advocate” in the smart home field, toward three primary principles:

  • Data privacy, which means devices with local-only options, and cloud services with explicit permissions
  • Choice in using devices with one another through open standards and local APIs
  • Sustainability by repurposing old devices and appliances beyond company-defined lifetimes

Notably, individuals cannot contribute modest-size donations to the Open Home Foundation. Instead, the foundation asks supporters to purchase a Nabu Casa subscription or contribute code or other help to its open source projects.

From a few lines of Python to a foundation

Home Assistant founder Paulus Schoutsen wanted better control of his Philips Hue smart lights just before 2014 or so and wrote a Python script to do so. Thousands of volunteer contributions later, Home Assistant was becoming a real thing. Schoutsen and other volunteers inevitably started to feel overwhelmed by the “free time” coding and urgent bug fixes. So Schoutsen, Ben Bangert, and Pascal Vizeli founded Nabu Casa, a for-profit firm intended to stabilize funding and paid work on Home Assistant.

Through that stability, Home Assistant could direct full-time work to various projects, take ownership of things like ESPHome, and officially contribute to open standards like Zigbee, Z-Wave, and Matter. But Home Assistant was “floating in a kind of undefined space between a for-profit entity and an open-source repository on GitHub,” according to the foundation. The Open Home Foundation creates the formal home for everything that needs it and makes Nabu Casa a “special, rules-bound inaugural partner” to better delineate the business and non-profit sides.

Home Assistant as a Home Depot box?

In an interview with The Verge’s Jennifer Pattison Tuohy, and in a State of the Open Home stream over the weekend, Schoutsen also suggested that the Foundation gives Home Assistant a more stable footing by which to compete against the bigger names in smart homes, like Amazon, Google, Apple, and Samsung. The Home Assistant Green starter hardware will sell on Amazon this year, along with HA-badged extension dongles. A dedicated voice control hardware device that enables a local voice assistant is coming before year’s end. Home Assistant is partnering with Nvidia and its Jetson edge AI platform to help make local assistants better, faster, and more easily integrated into a locally controlled smart home.

That also means Home Assistant is growing as a brand, not just a product. Home Assistant’s “Works With” program is picking up new partners and has broad ambitions. “We want to be a consumer brand,” Schoutsen told Tuohy. “You should be able to walk into a Home Depot and be like, ‘I care about my privacy; this is the smart home hub I need.’”

Where does this leave existing Home Assistant enthusiasts, who are probably familiar with the feeling of a tech brand pivoting away from them? It’s hard to imagine Home Assistant dropping its advanced automation tools and YAML-editing offerings entirely. But Schoutsen suggested he could imagine a split between regular and “advanced” users down the line. But Home Assistant’s open nature, and now its foundation, should ensure that people will always be able to remix, reconfigure, or re-release the version of smart home choice they prefer.

Intel’s “Gaudi 3” AI accelerator chip may give Nvidia’s H100 a run for its money

Adventures in Matrix Multiplication —

Intel claims 50% more speed when running AI language models vs. the market leader.

An Intel handout photo of the Gaudi 3 AI accelerator.

Enlarge / An Intel handout photo of the Gaudi 3 AI accelerator.

On Tuesday, Intel revealed a new AI accelerator chip called Gaudi 3 at its Vision 2024 event in Phoenix. With strong claimed performance while running large language models (like those that power ChatGPT), the company has positioned Gaudi 3 as an alternative to Nvidia’s H100, a popular data center GPU that has been subject to shortages, though apparently that is easing somewhat.

Compared to Nvidia’s H100 chip, Intel projects a 50 percent faster training time on Gaudi 3 for both OpenAI’s GPT-3 175B LLM and the 7-billion parameter version of Meta’s Llama 2. In terms of inference (running the trained model to get outputs), Intel claims that its new AI chip delivers 50 percent faster performance than H100 for Llama 2 and Falcon 180B, which are both relatively popular open-weights models.

Intel is targeting the H100 because of its high market share, but the chip isn’t Nvidia’s most powerful AI accelerator chip in the pipeline. Announcements of the H200 and the Blackwell B200 have since surpassed the H100 on paper, but neither of those chips is out yet (the H200 is expected in the second quarter of 2024—basically any day now).

Meanwhile, the aforementioned H100 supply issues have been a major headache for tech companies and AI researchers who have to fight for access to any chips that can train AI models. This has led several tech companies like Microsoft, Meta, and OpenAI (rumor has it) to seek their own AI-accelerator chip designs, although that custom silicon is typically manufactured by either Intel or TSMC. Google has its own line of tensor processing units (TPUs) that it has been using internally since 2015.

Given those issues, Intel’s Gaudi 3 may be a potentially attractive alternative to the H100 if Intel can hit an ideal price (which Intel has not provided, but an H100 reportedly costs around $30,000–$40,000) and maintain adequate production. AMD also manufactures a competitive range of AI chips, such as the AMD Instinct MI300 Series, that sell for around $10,000–$15,000.

Gaudi 3 performance

An Intel handout featuring specifications of the Gaudi 3 AI accelerator.

Enlarge / An Intel handout featuring specifications of the Gaudi 3 AI accelerator.

Intel says the new chip builds upon the architecture of its predecessor, Gaudi 2, by featuring two identical silicon dies connected by a high-bandwidth connection. Each die contains a central cache memory of 48 megabytes, surrounded by four matrix multiplication engines and 32 programmable tensor processor cores, bringing the total cores to 64.

The chipmaking giant claims that Gaudi 3 delivers double the AI compute performance of Gaudi 2 using 8-bit floating-point infrastructure, which has become crucial for training transformer models. The chip also offers a fourfold boost for computations using the BFloat 16-number format. Gaudi 3 also features 128GB of the less expensive HBMe2 memory capacity (which may contribute to price competitiveness) and features 3.7TB of memory bandwidth.

Since data centers are well-known to be power hungry, Intel emphasizes the power efficiency of Gaudi 3, claiming 40 percent greater inference power-efficiency across Llama 7B and 70B parameters, and Falcon 180B parameter models compared to Nvidia’s H100. Eitan Medina, chief operating officer of Intel’s Habana Labs, attributes this advantage to Gaudi’s large-matrix math engines, which he claims require significantly less memory bandwidth compared to other architectures.

Gaudi vs. Blackwell

An Intel handout photo of the Gaudi 3 AI accelerator.

Enlarge / An Intel handout photo of the Gaudi 3 AI accelerator.

Last month, we covered the splashy launch of Nvidia’s Blackwell architecture, including the B200 GPU, which Nvidia claims will be the world’s most powerful AI chip. It seems natural, then, to compare what we know about Nvidia’s highest-performing AI chip to the best of what Intel can currently produce.

For starters, Gaudi 3 is being manufactured using TSMC’s N5 process technology, according to IEEE Spectrum, narrowing the gap between Intel and Nvidia in terms of semiconductor fabrication technology. The upcoming Nvidia Blackwell chip will use a custom N4P process, which reportedly offers modest performance and efficiency improvements over N5.

Gaudi 3’s use of HBM2e memory (as we mentioned above) is notable compared to the more expensive HBM3 or HBM3e used in competing chips, offering a balance of performance and cost-efficiency. This choice seems to emphasize Intel’s strategy to compete not only on performance but also on price.

As far as raw performance comparisons between Gaudi 3 and the B200, that can’t be known until the chips have been released and benchmarked by a third party.

As the race to power the tech industry’s thirst for AI computation heats up, IEEE Spectrum notes that the next generation of Intel’s Gaudi chip, code-named Falcon Shores, remains a point of interest. It also remains to be seen whether Intel will continue to rely on TSMC’s technology or leverage its own foundry business and upcoming nanosheet transistor technology to gain a competitive edge in the AI accelerator market.

AMD promises big upscaling improvements and a future-proof API in FSR 3.1

API should help more games get future FSR improvements without a game update.

AMD promises big upscaling improvements and a future-proof API in FSR 3.1

AMD

Last summer, AMD debuted the latest version of its FidelityFX Super Resolution (FSR) upscaling technology. While version 2.x focused mostly on making lower-resolution images look better at higher resolutions, version 3.0 focused on AMD’s “Fluid Motion Frames,” which attempt to boost FPS by generating interpolated frames to insert between the ones that your GPU is actually rendering.

Today, the company is announcing FSR 3.1, which among other improvements decouples the upscaling improvements in FSR 3.x from the Fluid Motion Frames feature. FSR 3.1 will be available “later this year” in games whose developers choose to implement it.

Fluid Motion Frames and Nvidia’s equivalent DLSS Frame Generation usually work best when a game is already running at a high frame rate, and even then can be more prone to mistakes and odd visual artifacts than regular FSR or DLSS upscaling. FSR 3.0 was an all-or-nothing proposition, but version 3.1 should let you pick and choose what features you want to enable.

It also means you can use FSR 3.0 frame generation with other upscalers like DLSS, especially useful for 20- and 30-series Nvidia GeForce GPUs that support DLSS upscaling but not DLSS Frame Generation.

“When using FSR 3 Frame Generation with any upscaling quality mode OR with the new ‘Native AA’ mode, it is highly recommended to be always running at a minimum of ~60 FPS before Frame Generation is applied for an optimal high-quality gaming experience and to mitigate any latency introduced by the technology,” wrote AMD’s Alexander Blake-Davies in the post announcing FSR 3.1.

Generally, FSR’s upscaling image quality falls a little short of Nvidia’s DLSS, but FSR 2 closed that gap a bit, and FSR 3.1 goes further. AMD highlights two specific improvements: one for “temporal stability,” which will help reduce the flickering and shimmering effect that FSR sometimes introduces, and one for ghosting reduction, which will reduce unintentional blurring effects for fast-moving objects.

The biggest issue with these new FSR improvements is that they need to be implemented on a game-to-game basis. FSR 3.0 was announced in August 2023, and AMD now trumpets that there are 40 “available and upcoming” games that support the technology, of which just 19 are currently available. There are a lot of big-name AAA titles in the list, but that’s still not many compared to the sum total of all PC games or even the 183 titles that currently support FSR 2.x.

AMD wants to help solve this problem in FSR 3.1 by introducing a stable FSR API for developers, which AMD says “makes it easier for developers to debug and allows forward compatibility with updated versions of FSR.” This may eventually lead to more games getting future FSR improvements for “free,” without the developer’s effort.

AMD didn’t mention any hardware requirements for FSR 3.1, though presumably, the company will still support a reasonably wide range of recent GPUs from AMD, Nvidia, and Intel. FSR 3.0 is formally supported on Radeon RX 5000, 6000, and 7000 cards, Nvidia’s RTX 20-series and newer, and Intel Arc GPUs. It will also bring FSR 3.x features to games that use the Vulkan API, not just DirectX 12, and the Xbox Game Development Kit (GDK) so it can be used in console titles as well as PC games.

Nvidia announces “moonshot” to create embodied human-level AI in robot form

Here come the robots —

As companies race to pair AI with general-purpose humanoid robots, Nvidia’s GR00T emerges.

In sci-fi films, the rise of humanlike artificial intelligence often comes hand in hand with a physical platform, such as an android or robot. While the most advanced AI language models so far seem mostly like disembodied voices echoing from an anonymous data center, they might not remain that way for long. Some companies like Google, Figure, Microsoft, Tesla, Boston Dynamics, and others are working toward giving AI models a body. This is called “embodiment,” and AI chipmaker Nvidia wants to accelerate the process.

“Building foundation models for general humanoid robots is one of the most exciting problems to solve in AI today,” said Nvidia CEO Jensen Huang in a statement. Huang spent a portion of Nvidia’s annual GTC conference keynote on Monday going over Nvidia’s robotics efforts. “The next generation of robotics will likely be humanoid robotics,” Huang said. “We now have the necessary technology to imagine generalized human robotics.”

To that end, Nvidia announced Project GR00T, a general-purpose foundation model for humanoid robots. As a type of AI model itself, Nvidia hopes GR00T (which stands for “Generalist Robot 00 Technology” but sounds a lot like a famous Marvel character) will serve as an AI mind for robots, enabling them to learn skills and solve various tasks on the fly. In a tweet, Nvidia researcher Linxi “Jim” Fan called the project “our moonshot to solve embodied AGI in the physical world.”

AGI, or artificial general intelligence, is a poorly defined term that usually refers to hypothetical human-level AI (or beyond) that can learn any task a human could without specialized training. Given a capable enough humanoid body driven by AGI, one could imagine fully autonomous robotic assistants or workers. Of course, some experts think that true AGI is long way off, so it’s possible that Nvidia’s goal is more aspirational than realistic. But that’s also what makes Nvidia’s plan a moonshot.

“The GR00T model will enable a robot to understand multimodal instructions, such as language, video, and demonstration, and perform a variety of useful tasks,” wrote Fan on X. “We are collaborating with many leading humanoid companies around the world, so that GR00T may transfer across embodiments and help the ecosystem thrive.” We reached out to Nvidia researchers, including Fan, for comment but did not hear back by press time.

Nvidia is designing GR00T to understand natural language and emulate human movements, potentially allowing robots to learn coordination, dexterity, and other skills necessary for navigating and interacting with the real world like a person. And as it turns out, Nvidia says that making robots shaped like humans might be the key to creating functional robot assistants.

So far, we’ve seen plenty of robotics platforms that aren’t human-shaped, including robot vacuum cleaners, autonomous weed pullers, industrial units used in automobile manufacturing, and even research arms that can fold laundry. So why focus on imitating the human form? “In a way, human robotics is likely easier,” said Huang in his GTC keynote. “And the reason for that is because we have a lot more imitation training data that we can provide robots, because we are constructed in a very similar way.”

That means that researchers can feed samples of training data captured from human movement into AI models that control robot movement, teaching them how to better move and balance themselves. Also, humanoid robots are particularly convenient because they can fit anywhere a person can, and we’ve designed a world of physical objects and interfaces (such as tools, furniture, stairs, and appliances) to be used or manipulated by the human form.

Along with GR00T, Nvidia also debuted a new computer platform called Jetson Thor, based on NVIDIA’s Thor system-on-a-chip (SoC), as part of the new Blackwell GPU architecture, which it hopes will power this new generation of humanoid robots. The SoC reportedly includes a transformer engine capable of 800 teraflops of 8-bit floating point AI computation for running models like GR00T.

Nvidia unveils Blackwell B200, the “world’s most powerful chip” designed for AI

There’s no knowing where we’re rowing —

208B transistor chip can reportedly reduce AI cost and energy consumption by up to 25x.

The GB200

On Monday, Nvidia unveiled the Blackwell B200 tensor core chip—the company’s most powerful single-chip GPU, with 208 billion transistors—which Nvidia claims can reduce AI inference operating costs (such as running ChatGPT) and energy consumption by up to 25 times compared to the H100. The company also unveiled the GB200, a “superchip” that combines two B200 chips and a Grace CPU for even more performance.

The news came as part of Nvidia’s annual GTC conference, which is taking place this week at the San Jose Convention Center. Nvidia CEO Jensen Huang delivered the keynote Monday afternoon. “We need bigger GPUs,” Huang said during his keynote. The Blackwell platform will allow the training of trillion-parameter AI models that will make today’s generative AI models look rudimentary in comparison, he said. For reference, OpenAI’s GPT-3, launched in 2020, included 175 billion parameters. Parameter count is a rough indicator of AI model complexity.

Nvidia named the Blackwell architecture after David Harold Blackwell, a mathematician who specialized in game theory and statistics and was the first Black scholar inducted into the National Academy of Sciences. The platform introduces six technologies for accelerated computing, including a second-generation Transformer Engine, fifth-generation NVLink, RAS Engine, secure AI capabilities, and a decompression engine for accelerated database queries.

Several major organizations, such as Amazon Web Services, Dell Technologies, Google, Meta, Microsoft, OpenAI, Oracle, Tesla, and xAI, are expected to adopt the Blackwell platform, and Nvidia’s press release is replete with canned quotes from tech CEOs (key Nvidia customers) like Mark Zuckerberg and Sam Altman praising the platform.

GPUs, once only designed for gaming acceleration, are especially well suited for AI tasks because their massively parallel architecture accelerates the immense number of matrix multiplication tasks necessary to run today’s neural networks. With the dawn of new deep learning architectures in the 2010s, Nvidia found itself in an ideal position to capitalize on the AI revolution and began designing specialized GPUs just for the task of accelerating AI models.

Nvidia’s data center focus has made the company wildly rich and valuable, and these new chips continue the trend. Nvidia’s gaming GPU revenue ($2.9 billion in the last quarter) is dwarfed in comparison to data center revenue (at $18.4 billion), and that shows no signs of stopping.

A beast within a beast

The aforementioned Grace Blackwell GB200 chip arrives as a key part of the new NVIDIA GB200 NVL72, a multi-node, liquid-cooled data center computer system designed specifically for AI training and inference tasks. It combines 36 GB200s (that’s 72 B200 GPUs and 36 Grace CPUs total), interconnected by fifth-generation NVLink, which links chips together to multiply performance.

“The GB200 NVL72 provides up to a 30x performance increase compared to the same number of NVIDIA H100 Tensor Core GPUs for LLM inference workloads and reduces cost and energy consumption by up to 25x,” Nvidia said.

That kind of speed-up could potentially save money and time while running today’s AI models, but it will also allow for more complex AI models to be built. Generative AI models—like the kind that power Google Gemini and AI image generators—are famously computationally hungry. Shortages of compute power have widely been cited as holding back progress and research in the AI field, and the search for more compute has led to figures like OpenAI CEO Sam Altman trying to broker deals to create new chip foundries.

While Nvidia’s claims about the Blackwell platform’s capabilities are significant, it’s worth noting that its real-world performance and adoption of the technology remain to be seen as organizations begin to implement and utilize the platform themselves. Competitors like Intel and AMD are also looking to grab a piece of Nvidia’s AI pie.

Nvidia says that Blackwell-based products will be available from various partners starting later this year.

Nvidia sued over AI training data as copyright clashes continue

In authors’ bad books —

Copyright suits over AI training data reportedly decreasing AI transparency.

Nvidia sued over AI training data as copyright clashes continue

Book authors are suing Nvidia, alleging that the chipmaker’s AI platform NeMo—used to power customized chatbots—was trained on a controversial dataset that illegally copied and distributed their books without their consent.

In a proposed class action, novelists Abdi Nazemian (Like a Love Story), Brian Keene (Ghost Walk), and Stewart O’Nan (Last Night at the Lobster) argued that Nvidia should pay damages and destroy all copies of the Books3 dataset used to power NeMo large language models (LLMs).

The Books3 dataset, novelists argued, copied “all of Bibliotek,” a shadow library of approximately 196,640 pirated books. Initially shared through the AI community Hugging Face, the Books3 dataset today “is defunct and no longer accessible due to reported copyright infringement,” the Hugging Face website says.

According to the authors, Hugging Face removed the dataset last October, but not before AI companies like Nvidia grabbed it and “made multiple copies.” By training NeMo models on this dataset, the authors alleged that Nvidia “violated their exclusive rights under the Copyright Act.” The authors argued that the US district court in San Francisco must intervene and stop Nvidia because the company “has continued to make copies of the Infringed Works for training other models.”

A Hugging Face spokesperson clarified to Ars that “Hugging Face never removed this dataset, and we did not host the Books3 dataset on the Hub.” Instead, “Hugging Face hosted a script that downloads the data from The Eye, which is the place where ELeuther hosted the data,” until “Eleuther removed the data from The Eye” over copyright concerns, causing the dataset script on Hugging Face to break.

Nvidia did not immediately respond to Ars’ request to comment.

Demanding a jury trial, authors are hoping the court will rule that Nvidia has no possible defense for both allegedly violating copyrights and intending “to cause further infringement” by distributing NeMo models “as a base from which to build further models.”

AI models decreasing transparency amid suits

The class action was filed by the same legal team representing authors suing OpenAI, whose lawsuit recently saw many claims dismissed, but crucially not their claim of direct copyright infringement. Lawyers told Ars last month that authors would be amending their complaints against OpenAI and were “eager to move forward and litigate” their direct copyright infringement claim.

In that lawsuit, the authors alleged copyright infringement both when OpenAI trained LLMs and when chatbots referenced books in outputs. But authors seemed more concerned about alleged damages from chatbot outputs, warning that AI tools had an “uncanny ability to generate text similar to that found in copyrighted textual materials, including thousands of books.”

Uniquely, in the Nvidia suit, authors are focused exclusively on Nvidia’s training data, seemingly concerned that Nvidia could empower businesses to create any number of AI models on the controversial dataset, which could affect thousands of authors whose works could allegedly be broadly infringed just by training these models.

There’s no telling yet how courts will rule on the direct copyright claims in either lawsuit—or in the New York Times’ lawsuit against OpenAI—but so far, OpenAI has failed to convince courts to toss claims aside.

However, OpenAI doesn’t appear very shaken by the lawsuits. In February, OpenAI said that it expected to beat book authors’ direct copyright infringement claim at a “later stage” of the case and, most recently in the New York Times case, tried to convince the court that NYT “hacked” ChatGPT to “set up” the lawsuit.

And Microsoft, a co-defendant in the NYT lawsuit, even more recently introduced a new argument that could help tech companies defeat copyright suits over LLMs. Last month, Microsoft argued that The New York Times was attempting to stop a “groundbreaking new technology” and would fail, just like movie producers attempting to kill off the VCR in the 1980s.

“Despite The Times’s contentions, copyright law is no more an obstacle to the LLM than it was to the VCR (or the player piano, copy machine, personal computer, Internet, or search engine),” Microsoft wrote.

In December, Hugging Face’s machine learning and society lead, Yacine Jernite, noted that developers appeared to be growing less transparent about training data after copyright lawsuits raised red flags about companies using the Books3 dataset, “especially for commercial models.”

Meta, for example, “limited the amount of information [it] disclosed about” its LLM, Llama-2, “to a single paragraph description and one additional page of safety and bias analysis—after [its] use of the Books3 dataset when training the first Llama model was brought up in a copyright lawsuit,” Jernite wrote.

Jernite warned that AI models lacking transparency could hinder “the ability of regulatory safeguards to remain relevant as training methods evolve, of individuals to ensure that their rights are respected, and of open science and development to play their role in enabling democratic governance of new technologies.” To support “more accountability,” Jernite recommended “minimum meaningful public transparency standards to support effective AI regulation,” as well as companies providing options for anyone to opt out of their data being included in training data.

“More data transparency supports better governance and fosters technology development that more reliably respects peoples’ rights,” Jernite wrote.

Review: AMD Radeon RX 7900 GRE GPU doesn’t quite earn its “7900” label

rabbit season —

New $549 graphics card is the more logical successor to the RX 6800 XT.

ASRock's take on AMD's Radeon RX 7900 GRE.

Andrew Cunningham

In July 2023, AMD released a new GPU called the “Radeon RX 7900 GRE” in China. GRE stands for “Golden Rabbit Edition,” a reference to the Chinese zodiac, and while the card was available outside of China in a handful of pre-built OEM systems, AMD didn’t make it widely available at retail.

That changes today—AMD is launching the RX 7900 GRE at US retail for a suggested starting price of $549. This throws it right into the middle of the busy upper-mid-range graphics card market, where it will compete with Nvidia’s $549 RTX 4070 and the $599 RTX 4070 Super, as well as AMD’s own $500 Radeon RX 7800 XT.

We’ve run our typical set of GPU tests on the 7900 GRE to see how it stacks up to the cards AMD and Nvidia are already offering. Is it worth buying a new card relatively late in this GPU generation, when rumors point to new next-gen GPUs from Nvidia, AMD, and Intel before the end of the year? Can the “Golden Rabbit Edition” still offer a good value, even though it’s currently the year of the dragon?

Meet the 7900 GRE

RX 7900 XT RX 7900 GRE RX 7800 XT RX 6800 XT RX 6800 RX 7700 XT RX 6700 XT RX 6750 XT

Total board power (TBP) 315 W 260 W 263 W 300 W 250 W 245 W 230 W 250 W

The 7900 GRE slots into AMD’s existing lineup above the RX 7800 XT (currently $500-ish) and below the RX 7900 (around $750). Technologically, we’re looking at the same Navi 31 GPU silicon as the 7900 XT and XTX, but with just 80 of the compute units enabled, down from 84 and 96, respectively. The normal benefits of the RDNA3 graphics architecture apply, including hardware-accelerated AV1 video encoding and DisplayPort 2.1 support.

The 7900 GRE also includes four active memory controller die (MCD) chiplets, giving it a narrower 256-bit memory bus and 16GB of memory instead of 20GB—still plenty for modern games, though possibly not quite as future-proof as the 7900 XT. The card uses significantly less power than the 7900 XT and about the same amount as the 7800 XT. That feels a bit weird, intuitively, since slower cards almost always consume less power than faster ones. But it does make some sense; pushing the 7800 XT’s smaller Navi 32 GPU to get higher clock speeds out of it is probably making it run a bit less efficiently than a larger Navi 31 GPU die that isn’t being pushed as hard.

When we reviewed the 7800 XT last year, we noted that its hardware configuration and performance made it seem more like a successor to the (non-XT) Radeon RX 6800, while it just barely managed to match or beat the 6800 XT in our tests. Same deal with the 7900 GRE, which is a more logical successor to the 6800 XT. Bear that in mind when doing generation-over-generation comparisons.
