CPUFreq Governor Tuning For Better AMD Ryzen Linux Performance
GraphicsMagick was also the slowest on the Ryzen 7 1800X when using the powersave governor. Ondemand and performance were doing the best for GraphicsMagick's OpenMP workload.
John The Ripper was in similar shape.
Powersave does go through the least amount of power compared to the other governors, so its performance-per-Watt is close, but at the cost of raw performance.
