AMD Blows Up Its Laptop CPU Numbering System

AMD is reverting to a simpler, more traditional numbering scheme for its laptop processors, abandoning its recent complex "decoder ring" system. The new system for Ryzen AI laptop processors will use a three-digit model number to denote generation and SKU, aligning more closely with industry norms. Ars Technica reports: 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. 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 [...].

The highlight of AMD's presentation Sunday at Computex 2024 was "the introduction of AMD's Ryzen AI 300 Series processors for laptops and the Ryzen 9000 Series for desktops," writes Slashdot reader BrianFagioli (sharing his report at Beta News): AMD's Ryzen AI 300 Series processors, designed for next-generation AI laptops, come with AMD's latest XDNA 2 architecture. This includes a Neural Processing Unit (NPU) that delivers 50 TOPS of AI processing power, significantly enhancing the AI capabilities of laptops. Among the processors announced were the Ryzen AI 9 HX 370, which features 12 cores and 24 threads with a boost frequency of 5.1 GHz, and the Ryzen AI 9 365 with 10 cores and 20 threads, boosting up to 5.0 GHz... In the desktop segment, the Ryzen 9000 Series processors, based on the "Zen 5" architecture, demonstrated an average 16% improvement in IPC performance over their predecessors built on the "Zen 4" architecture. The Ryzen 9 9950X stands out with 16 cores and 32 threads, reaching up to 5.7 GHz boost frequency and equipped with 80MB of cache... AMD also reaffirmed its commitment to the AM4 platform by introducing the Ryzen 9 5900XT and Ryzen 7 5800XT processors. These models are compatible with existing AM4 motherboards, providing an economical upgrade path for users. The article adds that AMD also unveiled its Radeon PRO W7900 Dual Slot workstation graphics card — priced at $3,499 — "further broadening its impact on high-performance computing... "AMD also emphasized its strategic partnerships with leading OEMs such as Acer, ASUS, HP, Lenovo, and MSI, who are set to launch systems powered by these new AMD processors." And there's also a software collaboration with Microsoft, reportedly "to enhance the capabilities of AI PCs, thus underscoring AMD's holistic approach to integrating AI into everyday computing."

AMD Core Performance Boost For Linux Getting Per-CPU Core Controls

An anonymous reader shared this report from Phoronix: For the past several months AMD Linux engineers have been working on AMD Core Performance Boost support for their P-State CPU frequency scaling driver. The ninth iteration of these patches were posted on Monday and besides the global enabling/disabling support for Core Performance Boost, it's now possible to selectively toggle the feature on a per-CPU core basis... The new interface is under /sys/devices/system/cpu/cpuX/cpufreq/amd_pstate_boost_cpb for each CPU core. Thus users can tune whether particular CPU cores are boosted above the base frequency.
