We have examined that as well, last week we tried a AMD 5950X which has half the amount of cores but much better single core performance - the result was still at 60% of the Epyc performance
- gjsman-1000 5y agoWhat was the M1 % relative to your Epyc?
- groundthrower 5y agoRoughly 10% faster
- gjsman-1000 5y agoHN makes us wait for replies… so if we need to continue this further I’m open at muse.theses-0z@icloud.com . My next question would be if you ran the 12900K in dual-channel memory.
- CobaltFire 5y agoHave 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.
