What was the M1 % relative to your Epyc?

Have you investigated memory constraints?

Ryzen is 2 channels; Epyc is 4-8 (depending on CPU). M1 has that stupidly fast/wide setup.

If your Epyc is one of the 4 channel optimized SKUs or is only running in 4 channel mode, you would get pretty close to the quoted ratios on a memory bandwidth test.

Correlation, not causation, but worth looking into.

Also check Node per Socket (NPS) settings on EPYC

HN makes us wait for replies… so if we need to continue this further I’m open at [email protected] .

My next question would be if you ran the 12900K in dual-channel memory.
