AMD EPYC 9755 DDR5-4800 vs. DDR5-6000 Memory Performance

With the newly-launched AMD EPYC 9005 series processors continuing to use Socket SP5, there is drop-in upgrade compatibility for existing EPYC 9004 series motherboards/servers. That's assuming, of course, the vendor provides a BIOS update for enabling the EPYC 9005 series "Turin" support and there may be limitations on the maximum CPU/TDP supported given power/thermal constraints. But in going from EPYC 9004 to EPYC 9005 is also upping the maximum memory speed from DDR5-4800 to DDR5-6000 (or DDR5-6400 in validated configurations). For those trying to weigh the benefits of also upgrading your memory if on an existing EPYC 9004 Genoa/Bergamo server to DDR5-6000, here are some memory performance comparison benchmarks for some reference points.
