DDR5 Memory Channel Scaling Performance With AMD EPYC 9004 Series
For those eyeing AMD EPYC Genoa server processors for use in a build farm / CI or other frequent code compilation environments with its up to 96 cores / 192 threads, there wasn't a measurable difference in build speed at 6 memory channels or higher -- even with using 384 parallel jobs for the EPYC 9654 2P server.
The Graph500 HPC benchmark obviously enjoyed the additional memory channels found with EPYC Genoa CPUs...
