  AVX-512 Performance Comparison: AMD Genoa vs. Intel Sapphire Rapids & Ice Lake
  https://www.phoronix.com/review/intel-sapphirerapids-avx512/3

  Gaming:
  "For the LeelaChessZero chess engine powered via neural networks, Sapphire Rapids enjoyed a larger relative performance boost with AVX-512 enabled than Ice Lake or Genoa. In this case it was also enough to push the Xeon Platinum 8490H 2P ahead of the EPYC 9654 2P."

  "
  When taking the geometric mean of all the raw AVX-512 benchmark results in this article, the Xeon Platinum 8380 2P "Ice Lake" performance went up by 34% with the AVX-512 enabled run where as the Xeon Platinum 8490H 2P "Sapphire Rapids" AVX-512 performance improved by 44% and the EPYC 9654 2P "Genoa" performance was up by 21% with AVX-512. Sapphire Rapids not only enjoyed much larger uplift from AVX-512 compared to with Ice Lake, but also a big win for power efficiency.
  
  The geometric mean also shows how important AVX-512 is for the success of 4th Gen EPYC Genoa in being competitive against 4th Gen Xeon Scalable for HPC workloads. Had Zen 4 not added AVX-512, the EPYC 9654 2P AVX-512-disabled results came out just behind the Xeon Platinum 8490H 2P with AVX-512 enabled. A Zen 4 server processor without AVX-512 would have been a neck-and-neck race between Sapphire Rapids and Genoa in more workloads. But instead the EPYC 9654 2P with AVX-512 came out 19% faster than the Xeon Platinum 8490H processors in this set of benchmarks."
