The AVX-512 Performance Advantage With AMD EPYC Bergamo

Phoronix - Thu, 07/27/2023 - 00:18
While this week was the surprise announcement of Intel AVX10 and with that taking the super-set of AVX-512 to both E and P core processors in the future, for next year's Xeon "Sierra Forest" server processors at up to 144 cores, it appears they will lack AVX-512/AVX10. Intel's AVX10 announcement noted initial support with Granite Rapids processors that will debut next year but no mention of the E-core-only Sierra Forest. With the AVX10 only coming to P/E core client processors after Granite Rapids, it would appear the high density Sierra Forest generation will miss out on AVX10/AVX-512 and not appear until Clearwater Forest. Meanwhile with the 128-core AMD EPYC "Bergamo" processors now shipping, there is AVX-512 with the Zen 4C cores. Here are some benchmarks looking at the AVX-512 impact for Bergamo.

NVK as the open-source NVIDIA Vulkan driver being developed for Mesa has to this point been developed out-of-tree as it's been in its early stages, depends upon Nouveau DRM kernel driver improvements, and ultimately isn't too useful until the Nouveau GSP/re-clocking situation is sorted out upstream. But overnight the merge request was opened to introduce NVK to mainline Mesa...
