    Skylake-X AVX-512 Throughput

    avxthrowaway

      There are conflicting reports regarding AVX-512 ability/throughput on the new Skylake-X processors. It is being reported that all non i9 Skylake-X processors only have half the AVX-512 "FMA units" of the i9 variants. However, several benchmarks are showing AVX-512 performance is comparable on the i7-7800X and i9-7900X, (links: http://forum.hwbot.org/showthread.php?t=170550&page=2 and http://www.pcgameshardware.de/Skylake-X-Codename-266252/News/Core-i7-7800X-AVX512-Durchsatz-1232713/ )

       

      Is it possible to comment on this discrepancy? If not, is there documentation on the Skylake-X processors which would resolve this?

       

      Thanks in advance!
