It looks like the monolithic silicon that succeeds "Phoenix," codenamed "Strix Point," will finally introduce an increase in CPU core counts for the thin-and-light and ultraportable mobile platforms. "Strix Point" is codename for the next-generation APU die being developed at AMD, which, according to a leaked MilkyWay@Home benchmark result, comes with a 12-core/24-thread CPU.

The silicon is identified by MilkyWay@Home with the OPN "AMD Eng Sample: 100-000000994-03_N," and CPU identification string "AuthenticAMD Family 26 Model 32 Stepping 0 -> B20F00." The "Strix Point" CPU could be the second time AMD has increased CPU core-counts per CCX. From "Zen 3" onward, the company increased the cores per CCX from 4 to 8, allowing a single "Zen 3" CCX on the "Cezanne" monolithic silicon to come with 8 cores. It's highly likely that with "Zen 5," the company is increasing the cores/CCX to 12, and that "Strix Point" has one of these CCXs.

As reported by Phoronix—references to GFX1150 & GFX1151 targets have been added to the AMDGPU LLVM backend/compiler, which seems to indicate that these are upcoming AMD APU models. AMD engineers have made to reference to GFX1150 as "Strix1" (full codename: Strix Point) in the past according to several sites, but the recent leak has GFX1151 mentioned for the first time.

Previous reports suggest that Team Red could be developing two Strix/Zen 5/RDNA 3.5 APUs with AI engine enhancements for laptops—a discovery of two separate GFX targets suggests that we are likely looking at different 12-core and 16-core models. The former is said to be a monolithic design with a TDP going up to 54 W. The 16-core "Strix Halo" (also known as "Starlak") is a very different type of product with leaks suggesting that it will have a maximum TDP of 120 W, and be based on a chiplet design. Zen 5 processor products are expected to arrive in the second half of 2024—with Granite Ridge filling in the desktop platform segment.

AMD in its 2022 Financial Analyst Day presentation announced the codename for the second generation of Ryzen desktop processors for Socket AM5, which is "Granite Ridge." A successor to the Ryzen 7000 "Raphael," the next-generation "Granite Ridge" processor will incorporate the "Zen 5" CPU microarchitecture, with its CPU complex dies (CCDs) built on the 4 nm silicon fabrication node. "Zen 5" will feature several core-level designs as detailed in our older article, including a redesigned front-end with greater parallelism, which should indicate a much large execution stage. The architecture could also incorporate AI/ML performance enhancements as AMD taps into Xilinx IP to add more fixed-function hardware backing the AI/ML capabilities of its processors.

The "Zen 5" microarchitecture makes its client debut with Ryzen "Granite Ridge," and server debut with EPYC "Turin." It's being speculated that AMD could give "Turin" a round of CPU core-count increases, while retaining the same SP5 infrastructure; which means we could see either smaller CCDs, or higher core-count per CCD with "Zen 5." Much like "Raphael," the next-gen "Granite Ridge" will be a series of high core-count desktop processors that will feature a functional iGPU that's good enough for desktop/productivity, though not gaming. AMD confirmed that it doesn't see "Raphael" as an APU, and that its definition of an "APU" is a processor with a large iGPU that's capable of gaming. The company's next such APU will be "Phoenix Point."

The recently leaked Windows 11 build appears to include certain optimizations for hybrid architecture processors. The developer preview provides a small improvement to Intel Lakefield processors and that boost will likely increase when Windows 11 officially launches. The Intel Lakefield processor family features a hybrid core design with 1 big core and 4 small cores, this is similar to the Apple M1 and similar hybrid designs are expected from AMD in the future. The Intel Lakefield Core i7-L16G7 CPU was tested by HotHardware and they measured performance improvements of 2% - 8% in various synthetic benchmarks including GeekBench 5, Cinebench R23, and PCMark 10. These performance improvements will benefit Intel's upcoming 12th generation Alder Lake processors and their Raptor Lake successors along with AMD's rumored Strix Point APUs.

Today, we have talked about AMD's upcoming Raphael lineup of processors in the article you can find here. However, it seems like the number of leaks on AMD's plans just keeps getting greater. Thanks to the "itacg" on Weibo, we have learned that AMD's Ryzen 8000 desktop series of processors are reportedly codenamed as Granite Ridge. This new codename denotes the Zen 5 based processors, manufactured on TSMC's 3 nm (N3) node. Another piece of information is that AMD's Ryzen 8000 series APUs are allegedly called Strix Point, and they also use the 3 nm technology, along with a combination of Zen 5 and Zen 4 core design IPs. We are not sure how this exactly works out, so we have to wait to find out more.
