AMD Ryzen 3 CPUFreq Governor Benchmarks On Linux 4.13
Using the Linux 4.13 Git kernel atop Ubuntu 17.04 with the AMD Ryzen 3 1200, I tested CPUFreq's ondemand, performance, powersave, schedutil, and conservative governors. As a reminder, Ubuntu defaults to CPUFreq's "ondemand" governor for AMD processors while the Intel CPUs using the P-State driver use "powersave" as their default.
All of these benchmarks were facilitated in a fully-automated and reproducible manner using the open-source Phoronix Test Suite.
In light tests like SQLite, the governor can make a small impact on the overall performance.
While for Linux gaming it tends to depend upon the title for how much of an impact the governor makes on the overall performance.
