AMD EPYC Turin Power Profile Selection Impact On Performance & Efficiency
Those wanting to see even more data from more than 170 benchmarks ran for this comparison, see this result file page for all of the raw data I collected during this round of benchmarking on the EPYC 9655 + Supermicro H13SSL-N server.
When taking the geometric mean of all the raw performance results, the default "high performance" power profile yielded the best performance with the ACPI CPUFreq performance governor. That though shouldn't be much of a surprise. Running in the Efficiency Mode with the ACPI CPUFreq schedutil configuration led to 75% the performance overall of the defaults.
Here is a look at the AC "wall" system power consumption of this EPYC Turin 1P server across all of the benchmarks conducted. The total server power consumption was 70% that of the highest Balanced Memory Performance mode.
The CPU power consumption in the Efficiency Mode was at 64% the highest average, which is a significant savings while enjoying ~75% the performance.
For those curious what the peak CPU frequency looked like across the duration of all the benchmarks conducted.
Going in-step with the power savings, the CPU thermals were also lower in the Efficiency Mode and other tuned Power Profile states.
That's the breakdown of data for those curious about AMD EPYC Turin with the Power Profile Selection options and using the ACPI CPUFreq driver. Again if you want to see even more workloads covered, there are 170+ benchmarks via this result file with all of the raw data collected. See last week's article for numbers with AMD P-State using completely different processors and server platform.
