One thing to note is that the benchmark is running on a Skylake Platinum chip which has two AVX512 FMAs.
You need a Gold 6000 series and above to see any benefit from AVX512. In most other cases the CPU throttles down some insane amount and there’s no to little benefit.
- nextos 9y agoIn this particular AVX512 use case or in most?
- jandrewrogers 9y agoThe much cheaper Xeon W-series, such as those in the iMac Pro, also have two AVX-512 FMAs.
- thecompilr 9y agoYou don't use FMA (or any multiplication) for SHA2. The throttling is a big issue.
- foobarbazetc 9y agoTrue. Did you guys get to test Epyc at CloudFlare? The 7401P seems pretty special. Like really great $ per perf. I think SuperMicro are coming out with 1 socket Epyc boards/servers.
