How GM’s Super Cruise went from limo driving to lane changes and towing

The Unified Lateral Controller

The algorithm that handles all of that is called the Unified Lateral Controller. “So it’s a single software stack, but it is also modular to adapt with different vehicle configurations, with different driving scenarios, different maneuvers,” Zarringhalam said.

“Let’s imagine that you’re driving a Super Cruise vehicle, and you indicate to the left, or the system automatically decides to make a lane change to the left, and then, for whatever reason, the driver decides that they want to go back, mid-maneuver; they want to go back to the original lane. So you can just indicate to the opposite side, in this case, the right-hand side. Under the hood, in this scenario, everything is jumping. Our target trajectory is jumping from a left-lane maneuver to a right turn. The turn can be very sharp. There could be other objects that narrow the envelope of operation that you’re allowed to function in,” Zarringhalam said.

Again, that behavior has to be consistent and predictable, whether it’s below freezing or in the middle of a heatwave, and things like tire wear must also be taken into account. Or, say, the presence of a trailer, which could be anything from a bike rack with wheels to a three-axle trailer.

“As soon as we detect that the trailer is attached, we run several real-time algorithms—trailer inertial parameters, trailer math, trailer configuration, even how many axles we have, and the control adapts itself to execute lane turning and keep both the vehicle and the trailer at the center of the road,” Zarringhalam said.

That’s done automatically without the driver having to input the information (obviating the problem of someone entering the wrong details), “and if you change the loading or the trailer configuration, even mid-drive—if you pull over, load more weight and continue driving on the same road with Super Cruise active—these learnings happen in a matter of seconds,” Zarringhalam said.

Skull long thought to be Cleopatra’s sister’s was actually a young boy

ancient DNA, ancient egypt, anthropology, Archaeology, cleopatra, forensic archaeology, Science / /

Scientists have demonstrated that an ancient human skull excavated from a tomb at Ephesos was not that of Arsinoë IV, half-sister to Cleopatra VII. Rather, it’s the skull of a young male between the ages of 11 and 14 from Italy or Sardinia, who may have suffered from one or more developmental disorders, according to a new paper published in the journal Scientific Reports. Arsinoë IV’s remains are thus still missing.

Arsinoë IV led quite an adventurous short life. She was either the third or fourth daughter of Ptolemy XII, who left the throne to Cleopatra and his son, Ptolemy XIII, to rule together. Ptolemy XIII didn’t care for this decision and dethroned Cleopatra in a civil war—until Julius Caesar intervened to enforce their father’s original plan of co-rulership. As for Arsinoë, Caesar returned Cyprus to Egyptian rule and named her and her youngest brother (Ptolemy XIV) co-rulers. This time, it was Arsinoë who rebelled, taking command of the Egyptian army and declaring herself queen.

She was fairly successful at first in battling the Romans, conducting a siege against Alexandria and Cleopatra, until her disillusioned officers decided they’d had enough and secretly negotiated with Caesar to turn her over to him. Caesar agreed, and after a bit of public humiliation, he granted Arsinoë sanctuary in the temple of Artemis in Ephesus. She lived in relative peace for a few years, until Cleopatra and Mark Antony ordered her execution on the steps of the temple—a scandalous violation of the temple as a place of sanctuary. Historians disagree about Arsinoë’s age when she died: Estimates range from 22 to 27.

Archaeologists have been excavating the ancient city of Ephesus for more than a century. The Octagon was uncovered in 1904, and the burial chamber was opened in 1929. That’s where Joseph Keil found a skeleton in a sarcophagus filled with water, but for some reason, Keil only removed the cranium from the tomb before sealing it back up. He took the skull with him to Germany and declared it belonged to a likely female around 20 years old, although he provided no hard data to support that conclusion.

It was Hilke Thur of the Austrian Academy of Sciences who first speculated that the skull may have belonged to Arsinoë IV, despite the lack of an inscription (or even any grave goods) on the tomb where it was found. Old notes and photographs, as well as craniometry, served as the only evidence. The skull accompanied Keil to his new position at the University of Vienna, and there was one 1953 paper reporting on craniometric measurements, but after that, the skull languished in relative obscurity. Archaeologists at the University of Graz rediscovered the skull in Vienna in 2022. The rest of the skeleton remained buried until the chamber was reopened and explored further in the 1980s and 1990s, but it was no longer in the sarcophagus.

Report: After many leaks, Switch 2 announcement could come “this week”

gaming, Nintendo, Nintendo Switch, nintendo switch 2, Switch, Tech / /

Nintendo may be getting ready to make its Switch 2 console official. According to “industry whispers” collected by Eurogamer, as well as reporting from The Verge’s Tom Warren, the Switch 2 could be formally announced sometime this week. Eurogamer suggests the reveal is scheduled for this Thursday, January 16.

The reporting also suggests that the reveal will focus mostly on the console’s hardware design, with another game-centered announcement coming later. Eurogamer reports that the console won’t be ready to launch until April; this would be similar to Nintendo’s strategy for the original Switch, which was announced in mid-January 2017 but not launched until March.

Many things about the Switch 2’s physical hardware design have been thoroughly leaked at this point, thanks mostly to accessory makers who have been showing off their upcoming cases. Accessory maker Genki was at CES last week with a 3D-printed replica of the console based on the real thing, suggesting a much larger but still familiar-looking console with a design and button layout similar to the current Switch.

On the inside, the console is said to sport a new Nvidia-designed Arm processor with a much more powerful GPU and more RAM than the current Switch. Dubbed “T239,” Eurogamer reports that the chip includes 1,536 CUDA cores based on the Ampere architecture, the same used in 2020’s GeForce RTX 30-series graphics cards on the PC.

Supreme Court lets Hawaii sue oil companies over climate change effects

climate change, fossil fuel companies, Hawaii, Honolulu, Policy, shell, Sunoco, Supreme Court / /

On Monday, the Supreme Court declined to decide whether to block lawsuits that Honolulu filed to seek billions in damages from oil and gas companies over allegedly deceptive marketing campaigns that hid the effects of climate change.

Now those lawsuits can proceed, surely frustrating the fossil fuel industry, which felt that SCOTUS should have weighed in on this key “recurring question of extraordinary importance to the energy industry” raised in lawsuits seeking similarly high damages in several states, CBS News reported.

Defendants Sunoco and Shell, along with 15 other energy companies, had asked the court to intervene and stop the Hawaii lawsuits from proceeding. They had hoped to move the cases out of Hawaii state courts by arguing that interstate pollution is governed by federal law and the Clean Air Act.

The oil and gas companies continue to argue that greenhouse gas emissions “flow from billions of daily choices, over more than a century, by governments, companies, and individuals about what types of fuels to use, and how to use them.” Because of this, the companies believe Honolulu was wrong to demand damages based on the “cumulative effect of worldwide emissions leading to global climate change.”

“In these cases, state and local governments are attempting to assert control over the nation’s energy policies by holding energy companies liable for worldwide conduct in ways that starkly conflict with the policies and priorities of the federal government,” oil and gas companies unsuccessfully argued in their attempt to persuade SCOTUS to grant review. “That flouts this court’s precedents and basic principles of federalism, and the court should put a stop to it.”

A glowing ring of metal fell to Earth, and no one has any idea what it is

ariane v, kenya, Space, space object / /

It has been more than a week since reports first emerged about a “glowing ring of metal” that fell from the sky and crashed near a remote village in Kenya.

According to the Kenya Space Agency, the object weighed 1,100 pounds (500 kg) and had a diameter of more than 8 feet (2.4 meters) when measured after it landed on December 30. A couple of days later, the space agency confidently reported that the object was a piece of space debris, saying it was a ring that separated from a rocket. “Such objects are usually designed to burn up as they re-enter the Earth’s atmosphere or to fall over unoccupied areas, such as the oceans,” the space agency told The New York Times.

Since those initial reports were published in Western media, a small band of dedicated space trackers have been using open source data to try to identify precisely which space object fell into Kenya. So far, they have not been able to identify the rocket launch to which the large ring can be attributed.

Now, some space trackers believe the object may not have come from space at all.

Did it really come from space?

Space is increasingly crowded, but large chunks of metal from rockets are generally not flying around in Earth orbit undetected and untracked.

“It was suggested that the ring is space debris, but the evidence is marginal,” wrote Jonathan McDowell, an astrophysicist working at the Harvard-Smithsonian Center for Astrophysics. McDowell is highly regarded for his analysis of space objects. “The most likely space-related possibility is the reentry of the SYLDA adapter from the Ariane V184 flight, object 33155. Nevertheless, I am not fully convinced that the ring is space debris at all,” he wrote.

Another prominent space tracker, Marco Langbroek, believes it’s plausible that the ring came from space, so he investigated further into objects that may have returned around the time of the object’s discovery in Kenya. In a blog post written Wednesday he noted that apart from the metal ring, other fragments looking consistent with space debris—including material that looks like carbon wrap and isolation foil—were found several kilometers away from the ring.

Here’s what we know, and what we don’t, about the awful Palisades wildfire

California, Los Angeles, palisades, Science, wildfire / /

Let’s start with the meteorology. The Palisades wildfire and other nearby conflagrations were well-predicted days in advance. After a typically arid summer and fall, the Los Angeles area has also had a dry winter so far. December, January, February, and March are usually the wettest months in the region by far. More than 80 percent of Los Angeles’ rain comes during these colder months. But this year, during December, the region received, on average, less than one-tenth of an inch of rainfall. Normal totals are on the order of 2.5 inches in December.

So, the foliage in the area was already very dry, effectively extending the region’s wildfire season. Then, strong Santa Ana winds were predicted for this week due, in part, to the extreme cold observed in the eastern United States and high pressure over the Great Basin region of the country. “Red flag” winds were forecast locally, which indicates that winds could combine with dry grounds to spread wildfires efficiently. The direct cause of the Palisades fire is yet unknown.

Wildfires during the winter months in California are not a normal occurrence, but they are not unprecedented either. Scientists, however, generally agree that a warmer planet is extending wildfire seasons such as those observed in California.

“Climate change, including increased heat, extended drought, and a thirsty atmosphere, has been a key driver in increasing the risk and extent of wildfires in the western United States during the last two decades,” the US National Oceanic and Atmospheric Administration concludes. “Wildfires require the alignment of a number of factors, including temperature, humidity, and the lack of moisture in fuels, such as trees, shrubs, grasses, and forest debris. All these factors have strong direct or indirect ties to climate variability and climate change.”

Why I’m disappointed with the TVs at CES 2025

Won’t someone please think of the viewer?

Op-ed: TVs miss opportunity for real improvement by prioritizing corporate needs.

The TV industry is hitting users over the head with AI and other questionable gimmicks Credit: Getty

If you asked someone what they wanted from TVs released in 2025, I doubt they’d say “more software and AI.” Yet, if you look at what TV companies have planned for this year, which is being primarily promoted at the CES technology trade show in Las Vegas this week, software and AI are where much of the focus is.

The trend reveals the implications of TV brands increasingly viewing themselves as software rather than hardware companies, with their products being customer data rather than TV sets. This points to an alarming future for smart TVs, where even premium models sought after for top-end image quality and hardware capabilities are stuffed with unwanted gimmicks.

LG’s remote regression

LG has long made some of the best—and most expensive—TVs available. Its OLED lineup, in particular, has appealed to people who use their TVs to watch Blu-rays, enjoy HDR, and the like. However, some features that LG is introducing to high-end TVs this year seem to better serve LG’s business interests than those users’ needs.

Take the new remote. Formerly known as the Magic Remote, LG is calling the 2025 edition the AI Remote. That is already likely to dissuade people who are skeptical about AI marketing in products (research suggests there are many such people). But the more immediately frustrating part is that the new remote doesn’t have a dedicated button for switching input modes, as previous remotes from LG and countless other remotes do.

To use the AI Remote to change the TV’s input—a common task for people using their sets to play video games, watch Blu-rays or DVDs, connect their PC, et cetera—you have to long-press the Home Hub button. Single-pressing that button brings up a dashboard of webOS (the operating system for LG TVs) apps. That functionality isn’t immediately apparent to someone picking up the remote for the first time and detracts from the remote’s convenience.

By overlooking other obviously helpful controls (play/pause, fast forward/rewind, and numbers) while including buttons dedicated to things like LG’s free ad-supported streaming TV (FAST) channels and Amazon Alexa, LG missed an opportunity to update its remote in a way centered on how people frequently use TVs. That said, it feels like user convenience didn’t drive this change. Instead, LG seems more focused on getting people to use webOS apps. LG can monetize app usage through, i.e., getting a cut of streaming subscription sign-ups, selling ads on webOS, and selling and leveraging user data.

Moving from hardware provider to software platform

LG, like many other TV OEMs, has been growing its ads and data business. Deals with data analytics firms like Nielsen give it more incentive to acquire customer data. Declining TV margins and rock-bottom prices from budget brands (like Vizio and Roku, which sometimes lose money on TV hardware sales and make up for the losses through ad sales and data collection) are also pushing LG’s software focus. In the case of the AI Remote, software prioritization comes at the cost of an oft-used hardware capability.

Further demonstrating its motives, in September 2023, LG announced intentions to “become a media and entertainment platform company” by offering “services” and a “collection of curated content in products, including LG OLED and LG QNED TVs.” At the time, the South Korean firm said it would invest 1 trillion KRW (about $737.7 million) into its webOS business through 2028.

Low TV margins, improved TV durability, market saturation, and broader economic challenges are all serious challenges for an electronics company like LG and have pushed LG to explore alternative ways to make money off of TVs. However, after paying four figures for TV sets, LG customers shouldn’t be further burdened to help LG accrue revenue.

Google TVs gear up for subscription-based features

There are numerous TV manufacturers, including Sony, TCL, and Philips, relying on Google software to power their TV sets. Numerous TVs announced at CES 2025 will come with what Google calls Gemini Enhanced Google Assistant. The idea that this is something that people using Google TVs have requested is somewhat contradicted by Google Assistant interactions with TVs thus far being “somewhat limited,” per a Lowpass report.

Nevertheless, these TVs are adding far-field microphones so that they can hear commands directed at the voice assistant. For the first time, the voice assistant will include Google’s generative AI chatbot, Gemini, this year—another feature that TV users don’t typically ask for. Despite the lack of demand and the privacy concerns associated with microphones that can pick up audio from far away even when the TV is off, companies are still loading 2025 TVs with far-field mics to support Gemini. Notably, these TVs will likely allow the mics to be disabled, like you can with other TVs using far-field mics. But I still ponder about features/hardware that could have been implemented instead.

Google is also working toward having people pay a subscription fee to use Gemini on their TVs, PCWorld reported.

“For us, our biggest goal is to create enough value that yes, you would be willing to pay for [Gemini],” Google TV VP and GM Shalini Govil-Pai told the publication.

The executive pointed to future capabilities for the Gemini-driven Google Assistant on TVs, including asking it to “suggest a movie like Jurassic Park but suitable for young children” or to show “Bollywood movies that are similar to Mission: Impossible.”

She also pointed to future features like showing weather, top news stories, and upcoming calendar events when someone is near the TV, showing AI-generated news briefings, and the ability to respond to questions like “explain the solar system to a third-grader” with text, audio, and YouTube videos.

But when people have desktops, laptops, tablets, and phones in their homes already, how helpful are these features truly? Govil-Pai admitted to PCWorld that “people are not used to” using their TVs this way “so it will take some time for them to adapt to it.” With this in mind, it seems odd for TV companies to implement new, more powerful microphones to support features that Google acknowledges aren’t in demand. I’m not saying that tech companies shouldn’t get ahead of the curve and offer groundbreaking features that users hadn’t considered might benefit them. But already planning to monetize those capabilities—with a subscription, no less—suggests a prioritization of corporate needs.

Samsung is hungry for AI

People who want to use their TV for cooking inspiration often turn to cooking shows or online cooking videos. However, Samsung wants people to use its TV software to identify dishes they want to try making.

During CES, Samsung announced Samsung Food for TVs. The feature leverages Samsung TVs’ AI processors to identify food displayed on the screen and recommend relevant recipes. Samsung introduced the capability in 2023 as an iOS and Android app after buying the app Whisk in 2019. As noted by TechCrunch, though, other AI tools for providing recipes based on food images are flawed.

So why bother with such a feature? You can get a taste of Samsung’s motivation from its CES-announced deal with Instacart that lets people order off Instacart from Samsung smart fridges that support the capability. Samsung Food on TVs can show users the progress of food orders placed via the Samsung Food mobile app on their TVs. Samsung Food can also create a shopping list for recipe ingredients based on what it knows (using cameras and AI) is in your (supporting) Samsung fridge. The feature also requires a Samsung account, which allows the company to gather more information on users.

Other software-centric features loaded into Samsung TVs this year include a dedicated AI button on the new TVs’ remotes, the ability to use gestures to control the TV but only if you’re wearing a Samsung Galaxy Watch, and AI Karaoke, which lets people sing karaoke using their TVs by stripping vocals from music playing and using their phone as a mic.

Like LG, Samsung has shown growing interest in ads and data collection. In May, for example, it expanded its automatic content recognition tech to track ad exposure on streaming services viewed on its TVs. It also has an ads analytics partnership with Experian.

Large language models on TVs

TVs are mainstream technology in most US homes. Generative AI chatbots, on the other hand, are emerging technology that many people have yet to try. Despite these disparities, LG and Samsung are incorporating Microsoft’s Copilot chatbot into 2025 TVs.

LG claims that Copilot will help its TVs “understand conversational context and uncover subtle user intentions,” adding: “Access to Microsoft Copilot further streamlines the process, allowing users to efficiently find and organize complex information using contextual cues. For an even smoother and more engaging experience, the AI chatbot proactively identifies potential user challenges and offers timely, effective solutions.”

Similarly, Samsung, which is also adding Copilot to some of its smart monitors, said in its announcement that Copilot will help with “personalized content recommendations.” Samsung has also said that Copilot will help its TVs understand strings of commands, like increasing the volume and changing the channel, CNET noted. Samsung said it intends to work with additional AI partners, namely Google, but it’s unclear why it needs multiple AI partners, especially when it hasn’t yet seen how people use large language models on their TVs.

TV-as-a-platform

To be clear, this isn’t a condemnation against new, unexpected TV features. This also isn’t a censure against new TV apps or the usage of AI in TVs.

AI marketing hype is real and misleading regarding the demand, benefits, and possibilities of AI in consumer gadgets. However, there are some cases when innovative software, including AI, can improve things that TV users not only care about but actually want or need. For example, some TVs use AI for things like trying to optimize sound, color, and/or brightness, including based on current environmental conditions or upscaling. This week, Samsung announced AI Live Translate for TVs. The feature is supposed to be able to translate foreign language closed captions in real time, providing a way for people to watch more international content. It’s a feature I didn’t ask for but can see being useful and changing how I use my TV.

But a lot of this week’s TV announcements underscore an alarming TV-as-a-platform trend where TV sets are sold as a way to infiltrate people’s homes so that apps, AI, and ads can be pushed onto viewers. Even high-end TVs are moving in this direction and amplifying features with questionable usefulness, effectiveness, and privacy considerations. Again, I can’t help but wonder what better innovations could have come out this year if more R&D was directed toward hardware and other improvements that are more immediately rewarding for users than karaoke with AI.

The TV industry is facing economic challenges, and, understandably, TV brands are seeking creative solutions for making money. But for consumers, that means paying for features that you’re likely to ignore. Ultimately, many people just want a TV with amazing image and sound quality. Finding that without having to sift through a bunch of fluff is getting harder.

China is having standard flu season despite widespread HMPV fears

CDC, china, ECDC, flu, health, HMPV, illness, infections, infectious diseases, respiratory, Science, seasonal, WHO / /

There’s a good chance you’ve seen headlines about HMPV recently, with some touting “what you need to know” about the virus, aka human metapneumovirus. The answer is: not much.

It’s a common, usually mild respiratory virus that circulates every year, blending into the throng of other seasonal respiratory illnesses that are often indistinguishable from one another. (The pack includes influenza virus, respiratory syncytial virus (RSV), adenovirus, parainfluenza virus, common human coronaviruses, bocavirus, rhinovirus, enteroviruses, and Mycoplasma pneumoniae, among others.) HMPV is in the same family of viruses as RSV.

As one viral disease epidemiologist at the US Centers for Disease Control summarized in 2016, it’s usually “clinically indistinguishable” from other bog-standard respiratory illnesses, like seasonal flu, that cause cough, fever, and nasal congestion. For most, the infection is crummy but not worth a visit to a doctor. As such, testing for it is limited. But, like other common respiratory infections, it can be dangerous for children under age 5, older adults, and those with compromised immune systems. It was first identified in 2001, but it has likely been circulating since at least 1958.

The situation in China

The explosion of interest in HMPV comes after reports of a spike of HMPV infections in China, which allegedly led to hordes of masked patients filling hospitals. But none of that appears to be accurate. While HMPV infections have risen, the increase is not unusual for the respiratory illness season. Further, HMPV is not the leading cause of respiratory illnesses in China right now; the leading cause is seasonal flu. And the surge in seasonal flu is also within the usual levels seen at this time of year in China.

Last week, the Chinese Center for Disease Control and Prevention released its sentinel respiratory illness surveillance data collected in the last week of December. It included the test results of respiratory samples taken from outpatients. Of those, 30 percent were positive for flu (the largest share), a jump of about 6 percent from the previous week (the largest jump). Only 6 percent were positive for HMPV, which was about the same detection rate as in the previous week (there was a 0.1 percent increase).

Dirty deeds in Denver: Ex-prosecutor faked texts, destroyed devices to frame colleague

Colorado, framed, legal, Policy / /

How we got here

Choi was a young attorney a few years out of law school, working at the Denver District Attorney’s Office in various roles between 2019 and 2022. Beginning in 2021, she accused her colleague, Dan Hines, of sexual misconduct. Hines, she said at first, made an inappropriate remark to her. Hines denied it and nothing could be proven, but he was still transferred to another unit.

In 2022, Choi complained again. This time, she offered phone records showing inappropriate text messages she allegedly received from Hines. But Hines, who denied everything, offered investigators his own phone records, which showed no texts to Choi.

Investigators then went directly to Verizon for records, which showed that “Ms. Choi had texted the inappropriate messages to herself,” according to the Times. “In addition, she changed the name in her phone to make it appear as though Mr. Hines was the one who had sent them.”

At this point, the investigators started looking more closely at Choi and asked for her devices, leading to the incident described above.

In the end, Choi was fired from the DA’s office and eventually given a disbarment order by the Office of the Presiding Disciplinary Judge, which she can still appeal. For his part, Hines is upset about how he was treated during the whole situation and has filed a lawsuit of his own against the DA’s office, believing that he was initially seen as a guilty party even in the absence of evidence.

The case is a reminder that, despite well-founded concerns over tracking, data collection, and privacy, sometimes the modern world’s massive data collection can work to one’s benefit. Hines was able to escape the second allegation against him precisely because of the specific (and specifically refutable) digital evidence that was presented against him—as opposed to the murkier world of “he said/she said.”

Choi might have done as she liked with her devices, but her “evidence” wasn’t the only data out there. Investigators were able to draw on Hines’ own phone data, along with Verizon network data, to see that he had not been texting Choi at the times in question.

Update: Ars Technica has obtained the ruling, which you can read here (PDF). The document recounts in great detail what a modern, quasi-judicial workplace investigation looks like: forensic device examinations, search warrants to Verizon, asking people to log into their cell phone accounts and download data while investigators look over their shoulders, etc.

New GeForce 50-series GPUs: There’s the $1,999 5090, and there’s everything else

Nvidia has good news and bad news for people building or buying gaming PCs.

The good news is that three of its four new RTX 50-series GPUs are the same price or slightly cheaper than the RTX 40-series GPUs they’re replacing. The RTX 5080 is $999, the same price as the RTX 4080 Super; the 5070 Ti and 5070 are launching for $749 and $549, each $50 less than the 4070 Ti Super and 4070 Super.

The bad news for people looking for the absolute fastest card they can get is that the company is charging $1,999 for its flagship RTX 5090 GPU, significantly more than the $1,599 MSRP of the RTX 4090. If you want Nvidia’s biggest and best, it will cost at least as much as four high-end game consoles or a pair of decently specced midrange gaming PCs.

Nvidia also announced a new version of its upscaling algorithm, DLSS 4. As with DLSS 3 and the RTX 40-series, DLSS 4’s flagship feature will be exclusive to the 50-series. It’s called DLSS Multi Frame Generation, and as the name implies, it takes the Frame Generation feature from DLSS 3 and allows it to generate even more frames. It’s why Nvidia CEO Jensen Huang claimed that the $549 RTX 5070 performed like the $1,599 RTX 4090; it’s also why those claims are a bit misleading.

The rollout will begin with the RTX 5090 and 5080 on January 30. The 5070 Ti and 5070 will follow at some point in February. All cards except the 5070 Ti will come in Nvidia-designed Founders Editions as well as designs made by Nvidia’s partners; the 5070 Ti isn’t getting a Founders Edition.

The RTX 5090 and 5080

RTX 5090 RTX 4090 RTX 5080 RTX 4080 Super
CUDA Cores 21,760 16,384 10,752 10,240
Boost Clock 2,410 MHz 2,520 MHz 2,617 MHz 2,550 MHz
Memory Bus Width 512-bit 384-bit 256-bit 256-bit
Memory Bandwidth 1,792 GB/s 1,008 GB/s 960 GB/s 736 GB/s
Memory size 32GB GDDR7 24GB GDDR6X 16GB GDDR7 16GB GDDR6X
TGP 575 W 450 W 360 W 320 W

The RTX 5090, based on Nvidia’s new Blackwell architecture, is a gigantic chip with 92 billion transistors in it. And while it is double the price of an RTX 5080, you also get double the GPU cores and double the RAM and nearly double the memory bandwidth. Even more than the 4090, it’s being positioned head and shoulders above the rest of the GPUs in the family, and the 5080’s performance won’t come remotely close to it.

Although $1,999 is a lot to ask for a graphics card, if Nvidia can consistently make the RTX 5090 available at $2,000, it could still be an improvement over the pricing of the 4090, which regularly sold for well over $1,599 over the course of its lifetime, due in part to pandemic-fueled GPU shortages, cryptocurrency mining, and the generative AI boom. Companies and other entities buying them as AI accelerators may restrict the availability of the 5090, too, but Nvidia’s highest GPU tier has been well out of the price range of most consumers for a while now.

Despite the higher power budget—as predicted, it’s 125 W higher than the 4090 at 450 W, and Nvidia recommends a 1,000 W power supply or better—the physical size of the 5090 Founders Edition is considerably smaller than the 4090, which was large enough that it had trouble fitting into some computer cases. Thanks to a “high-density PCB” and redesigned cooling system, the 5090 Founders Edition is a dual-slot card that ought to fit into small-form-factor systems much more easily than the 4090. Of course, this won’t stop most third-party 5090 GPUs from being gigantic triple-fan monstrosities, but it is apparently possible to make a reasonably sized version of the card.

Moving on to the 5080, it looks like more of a mild update from last year’s RTX 4080 Super, with a few hundred more CUDA cores, more memory bandwidth (thanks to the use of GDDR7, since the two GPUs share the same 256-bit interface), and a slightly higher power budget of 360 W (compared to 320 W for the 4080 Super).

Having more cores and faster memory, in addition to whatever improvements and optimizations come with the Blackwell architecture, should help the 5080 easily beat the 4080 Super. But it’s an open question as to whether it will be able to beat the 4090, at least before you consider any DLSS-related frame rate increases. The 4090 has 52 percent more GPU cores, a wider memory bus, and 8GB more memory.

5070 Ti and 5070

RTX 5070 Ti RTX 4070 Ti Super RTX 5070 RTX 4070 Super
CUDA Cores 8,960 8,448 6,144 7,168
Boost Clock 2,452 MHz 2,610 MHz 2,512 MHz 2,475 MHz
Memory Bus Width 256-bit 256-bit 192-bit 192-bit
Memory Bandwidth 896 GB/s 672 GB/s 672 GB/s 504 GB/s
Memory size 16GB GDDR7 16GB GDDR6X 12GB GDDR7 12GB GDDR6X
TGP 300 W 285 W 250 W 220 W

At $749 and $549, the 5070 Ti and 5070 are slightly more within reach for someone who’s trying to spend less than $2,000 on a new gaming PC. Both cards hew relatively closely to the specs of the 4070 Ti Super and 4070 Super, both of which are already solid 1440p and 4K graphics cards for many titles.

Like the 5080, the 5070 Ti includes a few hundred more CUDA cores, more memory bandwidth, and slightly higher power requirements compared to the 4070 Ti Super. That the card is $50 less than the 4070 Ti Super was at launch is a nice bonus—if it can come close to or beat the RTX 4080 for $250 less, it could be an appealing high-end option.

The RTX 5070 is alone in having fewer CUDA cores than its immediate predecessor—6,144, down from 7,168. It is an upgrade from the original 4070, which had 5,888 CUDA cores, and GDDR7 and slightly faster clock speeds may still help it outrun the 4070 Super; like the other 50-series cards, it also comes with a higher power budget. But right now this card is looking like the closest thing to a lateral move in the lineup, at least before you consider the additional frame-generation capabilities of DLSS 4.

DLSS 4 and fudging the numbers

Many of Nvidia’s most ostentatious performance claims—including the one that the RTX 5070 is as fast as a 4090—factors in DLSS 4’s additional AI-generated frames. Credit: Nvidia

When launching new 40-series cards over the last two years, it was common for Nvidia to publish a couple of different performance comparisons to last-gen cards: one with DLSS turned off and one with DLSS and the 40-series-exclusive Frame Generation feature turned on. Nvidia would then lean on the DLSS-enabled numbers when making broad proclamations about a GPU’s performance, as it does in its official press release when it says the 5090 is twice as fast as the 4090, or as Huang did during his CES keynote when he claimed that an RTX 5070 offered RTX 4090 performance for $549.

DLSS Frame Generation is an AI feature that builds on what DLSS is already doing. Where DLSS uses AI to fill in gaps and make a lower-resolution image look like a higher-resolution image, DLSS Frame Generation creates entirely new frames and inserts them in between the frames that your GPU is actually rendering.

DLSS 4 now generates up to three frames for every frame the GPU is actually rendering. Used in concert with DLSS image upscaling, Nvidia says that “15 out of every 16 pixels” you see on your screen are being generated by its AI models. Credit: Nvidia

The RTX 50-series one-ups the 40-series with DLSS 4, another new revision that’s exclusive to its just-launched GPUs: DLSS Multi Frame Generation. Instead of generating one extra frame for every traditionally rendered frame, DLSS 4 generates “up to three additional frames” to slide in between the ones your graphics card is actually rendering—based on Nvidia’s slides, it looks like users ought to be able to control how many extra frames are being generated, just as they can control the quality settings for DLSS upscaling. Nvidia is leaning on the Blackwell architecture’s faster Tensor Cores, which it says are up to 2.5 times faster than the Tensor Cores in the RTX 40-series, to do the AI processing necessary to upscale rendered frames and to generate new ones.

Nvidia’s performance comparisons aren’t indefensible; with DLSS FG enabled, the cards can put out a lot of frames per second. It’s just dependent on game support (Nvidia says that 75 titles will support it at launch), and going off of our experience with the original iteration of Frame Generation, there will likely be scenarios where image quality is noticeably worse or just “off-looking” compared to actual rendered frames. DLSS FG also needed a solid base frame rate to get the best results, which may or may not be the case for Multi-FG.

Enhanced versions of older DLSS features can benefit all RTX cards, including the 20-, 30-, and 40-series. Multi-Frame Generation is restricted to the 50-series, though. Credit: Nvidia

Though the practice of restricting the biggest DLSS upgrades to all-new hardware is a bit frustrating, Nvidia did announce that it’s releasing a new transformer module for the DLSS Ray Reconstruction, Super Resolution, and Anti-Aliasing features. These are DLSS features that are available on all RTX GPUs going all the way back to the RTX 20-series, and games that are upgraded to use the newer models should benefit from improved upscaling quality even if they’re using older GPUs.

GeForce 50-series: Also for laptops!

Nvidia’s laptop GPU announcements sometimes trail the desktop announcements by a few weeks or months. But the company has already announced mobile versions of the 5090, 5080, 5070 Ti, and 5070 that Nvidia says will begin shipping in laptops priced between $1,299 and $2,899 when they launch in March.

All of these GPUs share names, the Blackwell architecture, and DLSS 4 support with their desktop counterparts, but per usual they’re significantly cut down to fit on a laptop motherboard and within a laptop’s cooling capacity. The mobile version of the 5090 includes 10,496 GPU cores, less than half the number of the desktop version, and just 24GB of GDDR7 memory on a 256-bit interface instead of 32GB on a 512-bit interface. But it also can operate with a power budget between 95 and 150 W, a fraction of what the desktop 5090 needs.

RTX 5090 (mobile) RTX 5080 (mobile) RTX 5070 Ti (mobile) RTX 5070 (mobile)
CUDA Cores 10,496 7,680 5,888 4,608
Memory Bus Width 256-bit 256-bit 192-bit 128-bit
Memory size 24GB GDDR7 16GB GDDR7 12GB GDDR7 8GB GDDR7
TGP 95-150 W 80-150 W 60-115 W 50-100 W

The other three GPUs are mostly cut down in similar ways, and all of them have fewer GPU cores and lower power requirements than their desktop counterparts. The 5070 GPUs both have less RAM and narrowed memory buses, too, but the mobile RTX 5080 at least comes closer to its desktop iteration, with the same 256-bit bus width and 16GB of RAM.

Lenovo laptop’s rollable screen uses motors to grow from 14 to 16.7 inches

CES, CES 2025, foldable, laptops, Lenovo, oled, Tech / /

Lenovo announced a laptop today that experiments with a new way to offer laptop users more screen space than the typical clamshell design. The Lenovo ThinkBook Plus Gen 6 Rollable has a screen that can roll up vertically to expand from 14 inches diagonally to 16.7 inches, presenting an alternative to prior foldable-screen and dual-screen laptops.

Here you can see the PC’s backside when the screen is extended. Lenovo

The laptop, which Lenovo says is coming out in June, builds on a concept that Lenovo demoed in February 2023. That prototype had a Sharp-made panel that initially measured 12.7 inches but could unroll to present a total screen size of 15.3 inches. Lenovo’s final product is working with a bigger display from Samsung Display, The Verge reported. Resolution-wise you’re going from 2,000×1,600 pixels (about 183 pixels per inch) to 2,000×2,350 (184.8 ppi), the publication said.

Users make the screen expand by pressing a dedicated button on the keyboard or by making a hand gesture at the PC’s webcam. Expansion entails about 10 seconds of loud whirring from the laptop’s motors. Lenovo executives told The Verge that the laptop was rated for at least 20,000 rolls up and down and 30,000 hinge openings and closings.

The system can also treat the expanded screens as two different 16:9 displays.

This is a clever way to offer a dual-screen experience without the flaws inherent to current dual-screen laptops, including distracting hinges and designs with questionable durability. However, 16.7 inches is a bit small for two displays. The dual-screen Lenovo Yoga Book 9i, for comparison, previously had two 13.3-inch displays for a total of 26.6 inches, and this year’s model has two 14-inch screens. Still, the ThinkBook, when its screen is fully expanded, is the rare laptop to offer a screen that’s taller than it is wide.

Still foldable OLED

At first, you might think that since the screen is described as “rollable” it may not have the same visible creases that have tormented foldable-screen devices since their inception. But the screen, reportedly from Samsung Display, still shows “little curls visible in the display, which are more obvious when it’s moving and there’s something darker onscreen,” as well as “plenty of smaller creases along its lower half” that aren’t too noticeable when using the laptop but that are clear when looking at the screen closely or when staring at it “from steeper angles,” The Verge reported.

“I’m getting dizzy”: Man films Waymo self-driving car driving around in circles

Cars, Policy, self-driving, waymo / /

Waymo says the problem only caused a delay of just over five minutes and that Johns was not charged for the trip. A spokesperson for Waymo, which is owned by Google parent Alphabet, told Ars today that the “looping event” occurred on December 9 and was later addressed during a regularly scheduled software update.

Waymo did not answer our question about whether the software update only addressed routing at the specific location the problem occurred at, or a more general routing problem that could have affected rides in other locations.

The problem affecting Johns’ ride occurred near the user’s pickup location, Waymo told us. The Waymo car took the rider to his destination after the roughly five-minute delay, the spokesperson said. “Our rider support agent did help initiate maneuvers that helped resolve the issue,” Waymo said.

Rider would like an explanation

CBS News states that Johns is “still not certain he was communicating with a real person or AI” when he spoke to the support rep in the car. However, the Waymo spokesperson told Ars that “all of our rider support staff are trained human operators.”

Waymo told Ars that the company tried to contact Johns after the incident and left him a voicemail. Johns still says that he never received an explanation of what caused the circling problem.

We emailed Johns today and received a reply from a public relations firm working on his behalf. “To date, Mike has not received an explanation as to the reason for the circling issue,” his spokesperson said. His spokesperson confirmed that Johns did not miss his flight.

It wasn’t clear from the video whether Johns tried to use the “pull over” functionality available in Waymo cars. “If at any time you want to end your ride early, tap the Pull over button in your app or on the passenger screen, and the car will find a safe spot to stop,” a Waymo support site says.

Johns’ spokesperson told us that “Mike was not immediately aware of the ‘pull over’ button,” so “he did not have an opportunity to use it before engaging with the customer service representative over the car speaker.”

While Waymo says all its agents are human, Johns’ spokesperson told Ars that “Mike is still unsure if he was speaking with a human or an AI agent.”
