AMD P-State vs. ACPI CPUFreq Testing With Ryzen Laptops On Linux 5.17
For most of the content creation workloads there wasn't a measurable difference for cases where the benchmarks go on for an extended period of time and tend to ramp up all the CPU cores to their maximum performance state.
AOM-AV1 led to a situation like some of the gaming tests where AMD P-State Schedutil was the notable outlier and led to slower performance on both laptops than all other tested combinations.
The rest of the benchmarks weren't particularly eventful but for those interested can find them on this OpenBenchmarking.org result page.
