AMD EPYC 9965 "Turin Dense" Delivers Better Performance/Power Efficiency vs. AmpereOne 192-Core ARM CPU
The AmpereOne A192-32X is bound to eight channels with DDR5-5200 memory where as AMD EPYC Turin allows 12 channel memory at DDR5-6000 speeds. Ampere Computing supposedly this quarter will ship AmpereOne M with 12 channel DDR5 memory support but the memory speeds have yet to be confirmed. The greater memory bandwidth for EPYC Turin benefits workloads like AMG.
The greater memory bandwidth and Zen 5 advantages helped the EPYC 9965 perform much better than AmpereOne. This EPYC 9965 run is also in a sub-optimal configuration due to DDR5 memory throttling in this benchmark due to an overheating issue with one of the DIMMs. But even with this subpar EPYC 9965 WRF run, it's still coming out well ahead of the AmpereOne CPU in this 192 core battle.
The AMD EPYC 9965 Turin Dense processor was delivering dominating performance in most of the HPC benchmarks tested compared to the AmpereOne A192-32X flagship ARM server processor.
