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. 256-bit data path vs. AVX-512 disabled. That was interesting for showing the benefits of Zen 5's full 512-bit data path support compared to the "double pumped" approach with Zen 4 or optionally used via a BIOS option on Zen 5. AVX-512 continues to prove to be very performant and power efficient with AMD Zen 5 processors unlike with the early generations of AVX-512 on Intel processors. Here is a fresh look at the AVX-512 performance on a Supermicro server with an AMD EPYC 9655 processor.
