For the second time in two years, AMD blows up its laptop CPU numbering system

this again —

AMD reverses course on “decoder ring” numbering system for laptop CPUs.

AMD's Ryzen 9 AI 300 series is a new chip and a new naming scheme.

AMD

Less than two years ago, AMD announced that it was overhauling its numbering scheme for laptop processors. Each digit in its four-digit CPU model numbers picked up a new meaning, which, with the help of a detailed reference sheet, promised to inform buyers of exactly what it was they were buying.

One potential issue with this, as we pointed out at the time, was that this allowed AMD to change over the first and most important of those four digits every single year that it decided to re-release a processor, regardless of whether that chip actually included substantive improvements or not. Thus a “Ryzen 7730U” from 2023 would look two generations newer than a Ryzen 5800U from 2021, despite being essentially identical.

AMD is partially correcting this today by abandoning the self-described “decoder ring” naming system and resetting it to something more conventional.

For its new Ryzen AI laptop processors, codenamed “Strix Point,” AMD is still using the same broad Ryzen 3/5/7/9 number to communicate general performance level plus a one- or two-letter suffix to denote general performance and power level (U for ultraportables, HX for higher-performance chips, and so on). A new three-digit processor number will inform buyers of the chip’s generation in the first digit and denote the specific SKU using the last two digits.

AMD is changing how it numbers its laptop CPUs again.

In other words, the company is essentially hitting the undo button.

Like Intel, AMD is shifting from four-digit numbers to three digits. The Strix Point processor numbers will start with the 300 series, which AMD says is because this is the third generation of Ryzen laptop processors with a neural processing unit (NPU) included. Current 7040-series and 8040-series processors with NPUs are not being renamed retroactively, and AMD plans to stop using the 7000- and 8000-series numbering for processor introductions going forward.

AMD wouldn’t describe exactly how it would approach CPU model numbers for new products that used older architectures but did say that new processors that didn’t meet the 40+ TOPS requirement for Microsoft’s Copilot+ program would simply use the “Ryzen” name instead of the new “Ryzen AI” branding. That would include older architectures with slower NPUs, like the current 7040 and 8040-series chips.

Desktop CPUs are, once again, totally unaffected by this change. Desktop processors’ four-digit model numbers and alphabetic suffixes generally tell you all you need to know about their underlying architecture; the new Ryzen 9000 desktop CPUs and the Zen 5 architecture were also announced today.

It seems like a lot of work to do to end up basically where we started, especially when the people at AMD who make and market the desktop chips have been getting by just fine with older model numbers for newly released products when appropriate. But to be fair to AMD, there just isn’t a great way to do processor model numbers in a simple and consistent way, at least not given current market realities:

  • PC OEMs that seem to demand or expect “new” product from chipmakers every year, even though chip companies tend to take somewhere between one and three years to release significantly updated designs.
  • The fact that casual and low-end users don’t actually benefit a ton from performance enhancements, keeping older chips viable for longer.
  • Different subsections of the market that must be filled with slightly different chips (consider chips with vPro versus similar chips without it).
  • The need to “bin” chips—that is, disable small parts of a given silicon CPU or GPU die and then sell the results as a lower-end product—to recoup manufacturing costs and minimize waste.

Apple may come the closest to what the “ideal” would probably be—one number for the overarching chip generation (M1, M3, etc.), one word like “Pro” or “Max” to communicate the general performance level, and a straightforward description of the number of CPU and GPU cores included, to leave flexibility for binning chips. But as usual, Apple occupies a unique position: it’s the only company putting its own processors into its own systems, and the company usually only updates a product when there’s something new to put in it, rather than reflexively announcing new models every time another CES or back-to-school season or Windows version rolls around.

In reverting to more traditional model numbers, AMD has at least returned to a system that people who follow CPUs will be broadly familiar with. It’s not perfect, and it leaves plenty of room for ambiguity as the product lineup gets more complicated. But it’s in the same vein as Intel’s rebranding of 13th-gen Core chips, the whole “Intel Processor” thing, or Qualcomm’s unfriendly eight-digit model numbers for its Snapdragon X Plus and Elite chips. AMD’s new nomenclature is a devil, but at least it’s one we know.

    AMD

  • A handful of architectural highlights from Zen 5.

    AMD

  • The performance improvements with Zen 5 are occasionally quite impressive, but on average we’re looking at a 16 percent increase over Zen 4 at the same clock speeds. That’s decent, but not as good as the move from Zen 3 to Zen 4.

    AMD

It’s been almost two years since AMD introduced its Ryzen 7000 series desktop CPUs and the Zen 4 CPU architecture. Today, AMD is announcing the first concrete details about their successors. The Ryzen 9000 CPUs begin shipping in July.

At a high level, the Ryzen 9000 series and Zen 5 architecture offer mostly incremental improvements over Ryzen 7000 (Ryzen 8000 on the desktop is used exclusively for Zen 4-based G-series CPUs with more powerful integrated GPUs). AMD says that Zen 5 is roughly 16 percent faster than Zen 4 at the same clock speeds, depending on the workload—certainly not nothing, and there are some workloads that perform much better. But that number is far short of the 29 percent jump between Zen 3 and Zen 4.

AMD and Intel have both compensated for mild single-core performance improvements in the past by adding more cores, but Ryzen 9000 doesn’t do that. From the 9600X to the 9950X, the chips offer between 6 and 16 full-size Zen 5 cores, the same as every desktop lineup since Zen 2 and the Ryzen 3000 series. De-lidded shots of the processors indicate that they’re still using a total of two or three separate chiplets: one or two CPU chiplets with up to 8 cores each, and a separate I/O die to handle connectivity. The CPU chiplets are manufactured on a TSMC N4 process, an upgrade from the 5nm process used for Ryzen 7000, while the I/O die is still made with a 6nm TSMC process.

Ryzen 9000 has the same layout as the last few generations of Ryzen desktop CPU—two CPU chiplets with up to eight cores each, and an I/O die to handle connectivity.

These chips include no Zen 5c E-cores, as older rumors suggested. Zen 5c is a version of Zen 5 that is optimized to take up less space in a silicon die, at the expense of higher clock speeds; Zen 5c cores are making their debut in the Ryzen AI 300-series laptop chips AMD also announced today. Boosting the number of E-cores has helped Intel match and surpass AMD’s multi-core performance, though Ryzen’s power consumption and efficiency have both outdone Intel’s throughout the 12th-, 13th-, and 14th-generation Core product cycles. Apple also uses a mix of P-cores and E-cores in its  high-end desktop CPU designs.

Ryzen 9000 doesn’t include any kind of neural processing unit (NPU), nor does AMD mention whether the Ryzen 7000’s RDNA 2-based integrated GPU has been upgraded or improved.

AMD is also announcing new X870 and X870E motherboard chipsets to accompany the new processors; as with the X670, the E-series chipset is actually a pair of chipsets on the same motherboard, boosting the number of available USB ports, M.2 slots, and PCIe slots.

The only real improvement here seems to be that all X870-series boards support USB4 and higher EXPO memory overclocking speeds by default. The chipsets also support PCIe 5.0 speeds for the main PCIe slot and M.2 slot, though the X670 chipsets already did this.

The processors’ power requirements aren’t changing, so users with 600-series motherboards ought to be able to use Ryzen 9000 CPUs with little to no performance penalty following a BIOS update.

  • AMD plans to keep the AM4 socket around as a budget platform until at least 2025, according to this slide.

    AMD

  • To that end, it’s announcing a couple more riffs on the old Zen 3-based Ryzen 5000 series, to entice budget builders and upgraders. Pricing hasn’t been announced.

    AMD

Ryzen 9000 doesn’t seem likely to resolve the biggest issues with the AM5 platform, namely the high costs relative to current-gen Intel systems, the high cost relative to AM4-based systems today, and even the high cost relative to AM4-based systems at the same point in the AM4 socket’s lifespan. Motherboards remain more expensive, DDR5 memory remains more expensive, and there are still no AM5 processors available for significantly less than $200.

According to AMD’s own timeline, it plans to keep the AM4 socket around until at least 2025. AM4 is still a surprisingly decent budget platform given that the socket was introduced eight years ago, and AMD does, in fact, continue to trickle out new Ryzen 5000-series CPUs to give buyers and upgrades more options. But it still means that system builders either need to choose between an expensive platform that has a future or a cheaper platform that’s more or less a dead end.

Ryzen 8000G review: An integrated GPU that can beat a graphics card, for a price

The most interesting thing about AMD's Ryzen 7 8700G CPU is the Radeon 780M GPU that's attached to it.

Enlarge / The most interesting thing about AMD’s Ryzen 7 8700G CPU is the Radeon 780M GPU that’s attached to it.

Andrew Cunningham

Put me on the short list of people who can get excited about the humble, much-derided integrated GPU.

Yes, most of them are afterthoughts, designed for office desktops and laptops that will spend most of their lives rendering 2D images to a single monitor. But when integrated graphics push forward, it can open up possibilities for people who want to play games but can only afford a cheap desktop (or who have to make do with whatever their parents will pay for, which was the big limiter on my PC gaming experience as a kid).

That, plus an unrelated but accordant interest in building small mini-ITX-based desktops, has kept me interested in AMD’s G-series Ryzen desktop chips (which it sometimes calls “APUs,” to distinguish them from the Ryzen CPUs). And the Ryzen 8000G chips are a big upgrade from the 5000G series that immediately preceded them (this makes sense, because as we all know the number 8 immediately follows the number 5).

We’re jumping up an entire processor socket, one CPU architecture, three GPU architectures, and up to a new generation of much faster memory; especially for graphics, it’s a pretty dramatic leap. It’s an integrated GPU that can credibly beat the lowest tier of currently available graphics cards, replacing a $100–$200 part with something a lot more energy-efficient.

As with so many current-gen Ryzen chips, still-elevated pricing for the socket AM5 platform and the DDR5 memory it requires limit the 8000G series’ appeal, at least for now.

From laptop to desktop

AMD's first Ryzen 8000 desktop processors are what the company used to call

Enlarge / AMD’s first Ryzen 8000 desktop processors are what the company used to call “APUs,” a combination of a fast integrated GPU and a reasonably capable CPU.

AMD

The 8000G chips use the same Zen 4 CPU architecture as the Ryzen 7000 desktop chips, but the way the rest of the chip is put together is pretty different. Like past APUs, these are actually laptop silicon (in this case, the Ryzen 7040/8040 series, codenamed Phoenix and Phoenix 2) repackaged for a desktop processor socket.

Generally, the real-world impact of this is pretty mild; in most ways, the 8700G and 8600G will perform a lot like any other Zen 4 CPU with the same number of cores (our benchmarks mostly bear this out). But to the extent that there is a difference, the Phoenix silicon will consistently perform just a little worse, because it has half as much L3 cache. AMD’s Ryzen X3D chips revolve around the performance benefits of tons of cache, so you can see why having less would be detrimental.

The other missing feature from the Ryzen 7000 desktop chips is PCI Express 5.0 support—Ryzen 8000G tops out at PCIe 4.0. This might, maybe, one day in the distant future, eventually lead to some kind of user-observable performance difference. Some recent GPUs use an 8-lane PCIe 4.0 interface instead of the typical 16 lanes, which limits performance slightly. But PCIe 5.0 SSDs remain rare (and PCIe 4.0 peripherals remain extremely fast), so it probably shouldn’t top your list of concerns.

The Ryzen 5 8500G is a lot different from the 8700G and 8600G, since some of the CPU cores in the Phoenix 2 chips are based on Zen 4c rather than Zen 4. These cores have all the same capabilities as regular Zen 4 ones—unlike Intel’s E-cores—but they’re optimized to take up less space rather than hit high clock speeds. They were initially made for servers, where cramming lots of cores into a small amount of space is more important than having a smaller number of faster cores, but AMD is also using them to make some of its low-end consumer chips physically smaller and presumably cheaper to produce. AMD didn’t send us a Ryzen 8500G for review, so we can’t see exactly how Phoenix 2 stacks up in a desktop.

The 8700G and 8600G chips are also the only ones that come with AMD’s “Ryzen AI” feature, the brand AMD is using to refer to processors with a neural processing unit (NPU) included. Sort of like GPUs or video encoding/decoding blocks, these are additional bits built into the chip that handle things that CPUs can’t do very efficiently—in this case, machine learning and AI workloads.

Most PCs still don’t have NPUs, and as such they are only barely used in current versions of Windows (Windows 11 offers some webcam effects that will take advantage of NPU acceleration, but for now that’s mostly it). But expect this to change as they become more common and as more AI-accelerated text, image, and video creating and editing capabilities are built into modern operating systems.

The last major difference is the GPU. Ryzen 7000 includes a pair of RDNA2 compute units that perform more or less like Intel’s desktop integrated graphics: good enough to render your desktop on a monitor or two, but not much else. The Ryzen 8000G chips include up to 12 RDNA3 CUs, which—as we’ve already seen in laptops and portable gaming systems like the Asus ROG Ally that use the same silicon—is enough to run most games, if just barely in some cases.

That gives AMD’s desktop APUs a unique niche. You can use them in cases where you can’t afford a dedicated GPU—for a time during the big graphics card shortage in 2020 and 2021, a Ryzen 5700G was actually one of the only ways to build a budget gaming PC. Or you can use them in cases where a dedicated GPU won’t fit, like super-small mini ITX-based desktops.

The main argument that AMD makes is the affordability one, comparing the price of a Ryzen 8700G to the price of an Intel Core i5-13400F and a GeForce GTX 1650 GPU (this card is nearly five years old, but it remains Nvidia’s newest and best GPU available for less than $200).

Let’s check on performance first, and then we’ll revisit pricing.
