With some benchmarks the EPYC 7773X with its large cache really still performs great in relation to Genoa, but with Sapphire Rapids HBM2e SKUs it's where these benchmarks would be very interesting as well, but unfortunately none on hand currently for testing.
In addition to the significant raw performance improvement generationally, the performance-per-Watt was also coming out better with Sapphire Rapids over Ice Lake. However, the Xeon Platinum 8490H was consistently pulling more power than the AMD Genoa processors.
