AMD EPYC 9554 & EPYC 9654 Benchmarks - Outstanding Performance For Linux HPC/Servers

In a single-threaded Node.js benchmark, Genoa was now able to come out ahead of Ice Lake thanks to the Zen 4 architectural improvements.

The simdjson JSON parsing benchmark normally isn't interesting for large server performance, but it is now that simdjson has an AVX-512 optimized path. The EPYC 9004 series processors were well ahead of Ice Lake now thanks to the Zen 4 AVX-512 support.

The power consumption also was comparable to Ice Lake with the CPUs not being fully saturated for the JSON parsing benchmark.

The EPYC 9554 was delivering the best performance-per-Watt for this AVX-512-capable parsing test for gigabytes of JSON data.

The single-threaded Python performance tests also showed the nice advancements with Zen 4.

And some very nice improvements for Numpy.

The single-threaded PHP performance of Genoa was now in a state only comparable to that of Ice Lake, but for a fully-loaded web server of course there is more capacity to be found with the Genoa and its higher core/thread counts.
