The Compelling AVX-512 Performance Advantage On AMD EPYC 9005 "Turin"
Back in October following the launch of the EPYC 9005 'Turin' processors I ran an AVX-512 performance comparison for the EPYC 9755 with 512-bit data path vs.
They also don't offer any prior versions of their BIOS on the Supermicro website, so I am still waiting to hear back from them with a solution for getting EPYC Zen 4 booting with this motherboard. Another caveat is that with the original AVX-512 benchmarks from October, the AMD Volcano BIOS allowed changing between the 256-bit and 512-bit data path for AVX-512. In any case these EPYC 9655 results are interesting on their own for a fresh look at the AVX-512 performance benefits and impact on CPU power consumption / thermals / clock frequency.
