AMD P-State v4 Linux Testing On A Ryzen 5 5500U
Written by Michael Larabel in Software on 24 November 2021. Page 5 of 5. 14 Comments

Across dozens of benchmarks, here is the geometric mean for all the raw benchmark figures conducted from this Ryzen 5 5500U laptop. The amd-pstate driver with the performance governor was ever so slightly faster than acpi-cpufreq, but when it came to the ondemand and schedutil governors that are often the default on Linux distributions, amd-pstate was still leading to slightly lower raw performance than acpi-cpufreq.

When looking at the CPU power consumption across the entire span of benchmarks conducted, the Ryzen 5 5500U was saving about 0.4 Watts on average with amd-pstate during the ondemand/schedutil governor runs.

The amd-pstate driver did lead to a lower SoC temperature in this Lenovo IdeaPad laptop by about one degree Celsius across the different governors benchmarked.

Those wishing to go through all of the raw benchmark results for the many different tests conducted as well as all of the individual power consumption and thermal numbers can go to this result file.
