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.
There are a lot more DDR5-4800 ECC RDIMMs available at major Internet retailers than DDR5-6000 if in a crunch or not running very memory bandwidth constrained workloads and trying to maximize your TCO savings. No other changes were made to this AMD EPYC 9755 server running Ubuntu 24.04 LTS besides comparing the memory speed in this article across dozens of workloads.
