The Epic Gains Made In 5 Years For AMD EPYC 7601 Naples vs. Newest 4th Gen EPYC Genoa

As what should be no surprise to anyone following AMD's epic strides the past five years with each succeeding Zen generation, it's a dramatic difference from the EPYC 7601 2P "Naples" processors to the new Genoa processors... With the EPYC 7601 2P providing a combined 64 cores / 128 threads, it was being slaughtered in heavy HPC workloads by a single EPYC 9374F 32-core / 64-thread CPU/

Or in the case of the NAMD molecular dynamics software, the EPYC 7601 2P managed to only match that EPYC 9374F CPU at half the core/thread count. If comparing flagship SKUs from Naples to Genoa, it's multiple times faster.

For those on EPYC Naples processors still that are hitting the five year mark, upgrading to Genoa can mean either going for 2P system and seeing dramatically better performance or if jaw-dropping performance isn't needed can instead mean condensing your server(s) down to 1P platforms for power / space gains and enjoying lower TCO.

With the demanding WRF weather forecasting benchmark, a single EPYC 9374F was twice as fast the two socket EPYC 7601... With the new flagship Genoa EPYC 9654 2P it ran the conus 2.5km model in just 19% the time it took the original EPYC Naples flagship hardware. Of course, if going for the power determinism mode with Genoa it can be even faster.

It was very entertaining to see how far the EPYC performance has evolved over the past five years since launch. It's too bad though the RAPL power monitoring Linux driver wasn't working correctly for Zen 1 for showing off the performance-per-Watt gains too.
