AMD’s next-gen Zen 5 processors have been spotted in the MilkyWay and Eienstien Home databases. The first chip is the 8-core Ryzen 7 8700X (or 8800X) with 16 threads. It’s an engineering sample from Family 26 (Zen 5), part of Stepping 0. The CPU is paired with 1,024KB of cache, which I suspect refers to the L2 cache per core. It is coupled with 32GB of DDR5 memory and nets a floating point/integer speed of 1000 million ops per sec.
The other SKU is part of the Strix Point family. The high-end mobile processor features a hybrid-core architecture comprising 8 high-performance “P” Zen 5 cores and 8 low-power “E” Zen 5c cores. Zen 5 and Zen 5c are based on the same ISA (Instructure Set Architecture) with support for the same set of instructions, including AVX-512. The only difference is in terms of the L3 cache, which has been trimmed to save die space. The rest of the components have also been repacked for a denser design.
Strix Point will succeed Phoenix Point sometime in late 2024. Leveraging the Zen 5 core architecture and the RDNA 3.5 graphics engine, it will power mainstream and upper midrange notebooks. The engineering sample spotted features 12 Zen 5 cores and 16 RDNA 3.5 Compute Units (CUs). In addition to the 12 Zen 5 cores and 16 graphics units, Strix Point will have a dedicated AI engine based on the XDNA architecture.
The iGPU will feature 768 stream processors with a boost clock of 2.5GHz to 3GHz. Strix Point will be joined by Strix Halo, which, as the name suggests, will be a Halo product. It’ll be a chiplet design with 16 Zen 5 cores across two CCDs and up to 40 Compute Units (debatable) or 2,560 stream processors. Strix Point has already been confirmed as the successor to Phoenix Point with Zen 5 CPU cores and an RDNA 3+ iGPU engine.
