With Windows 11 23H2 setting the stage for increased prevalence of AI in client PC use cases, the new hardware battleground between AMD and its rivals Intel, Apple, and Qualcomm, will be in equipping their mobile processors with sufficient AI acceleration performance. AMD already introduced accelerated AI with the current "Phoenix" processor that debuts Ryzen AI, and its Xilinx XDNA hardware backend that provides a performance of up to 16 TOPS. This will see a 2-3 fold increase with the company's 2024-25 mobile processor lineup, according to a roadmap leak by "Moore's Law is Dead."

At the very top of the pile, in a product segment called "ultimate compute," which consists of large gaming notebooks, mobile workstations, and desktop-replacements; the company's current Ryzen 7045 "Dragon Range" processor will continue throughout 2024. Essentially a non-socketed version of the desktop "Raphael" MCM, "Dragon Range" features up to two 5 nm "Zen 4" CCDs for up to 16 cores, and a 6 nm cIOD. This processor lacks any form of AI acceleration. In 2025, the processor will be succeeded with "Fire Range," a similar non-socketed, mobile-friendly MCM that's derived from "Granite Ridge," with up to two 4 nm "Zen 5" CCDs for up to 16 cores; and the 6 nm cIOD. What's interesting to note here, is that the quasi-roadmap makes no mention of AI acceleration for "Fire Range," which means "Granite Ridge" could miss out on Ryzen AI acceleration from the processor. Modern discrete GPUs from both NVIDIA and AMD support AI accelerators, so this must have been AMD's consideration to exclude an XDNA-based Ryzen AI accelerator on "Fire Range" and "Granite Ridge."

In recent developments, Linux's open-source graphics ecosystem is making significant strides to accommodate AMD's upcoming RDNA3.5 architecture, also known as RDNA3+ or GFX11.5. Mesa 23.3, a library in the Linux graphics software stack, is now being updated for RDNA3.5, marking a substantial milestone. This upcoming update is particularly tailored for the impending Ryzen 8000 "Strix Point" APU series, which will incorporate the Navi 3.5 architecture. While AMD has maintained secrecy regarding specific enhancements accompanying this refresh, we expect decent performance improvements. This includes the anticipation that the Ryzen 8000 APUs will feature an increased number of Compute Units (CUs), where the current highest number is 12 CUs, and the increase could bump that figure to 16 CUs. The official announcement of the Ryzen 8000 series is expected in early 2024 when we will learn more about its GPU configuration and performance.

"Strix Point" is the codename for AMD's next-generation mobile processor succeeding the current Ryzen 7040 series "Phoenix." More details of the processor emerged thanks to "All The Watts!!" on Twitter. The CPU of "Strix Point" will be heterogenous, in that it will feature two different kinds of CPU cores, but with essentially the same ISA and IPC. It is rumored that the processor will feature 4 "Zen 5" CPU cores, and 8 "Zen 5c" cores.

Both core types feature an identical IPC, but the "Zen 5" cores can hold onto higher boost frequencies, and have a wider frequency band, than the "Zen 5c" cores. From what we can deduce from the current "Zen 4c" cores, "Zen 5c" cores aren't strictly "efficiency" cores, as they still offer the full breadth of core ISA as "Zen 5," including SMT. In its maximum configuration, "Strix Point" will hence be a 12-core/24-thread processor. The two CPU core types sit in two different CCX (CPU core complexes), the "Zen 5" CCX has 4 cores sharing a 16 MB L3 cache, while the "Zen 5c" CCX shares a 16 MB L3 cache among 8 cores. AMD will probably use a software-based solution to ensure the right kind of workload from the OS is processed by the right kind of CPU core.
