CPUFreq Governor Tuning For Better AMD Ryzen Linux Performance

And lastly a look at the AC system power consumption through the entire duration of testing:

While the performance governor had the best results, it had the highest power use with an average of 120 Watts and a peak of 359 Watts. The ondemand governor had an average of 117 Watts and the schedutil governor came in at 116 Watts. Meanwhile, the conservative governor had an average of 101 Watts and a peak of 180 Watts while the powersave governor had an average of just 87 Watts with a peak of 346 Watts.

So if you care about performance with an AMD Ryzen box, the performance governor (to no surprise) works the best but at the cost of greater energy use. But the schedutil and ondemand governors tend to be quite close to the performance levels. Powersave really just works out well if you care about reducing energy use such as if running on battery power or looking to conserve heat output.
