The Impact Of The CPU Frequency Scaling Governor On AMD Threadripper 2990WX Linux Performance

First up was the TTSIOD multi-threaded renderer. Powersave was the slowest to no surprise followed by conservative and schedutil. When switching from ondemand (the Ubuntu default) to the performance governor yielded a 5% improvement in performance thanks to the more aggressive performance state changes.

While in a case like VP9 video encoding, there wasn't a large impact on performance besides powersave leading to noticeably lower performance.

But for x264 video encoding, switching from ondemand to performance governors yielded a 9.7% increase in performance.

Or in the case of x265 video encoding, switching from ondemand to performance led to an extra frame per second.
