Phoronix: AMDGPU Linux Gaming Tests With P-State vs. CPUFreq Scaling Drivers

The latest batch of open-source Linux benchmarks to share this weekend are doing some P-State and CPUFreq scaling driver benchmarks and also trying each driver's different CPU scaling governor options when using the AMD Radeon R9 285 graphics card on the AMDGPU kernel driver of Linux 4.5...

Michael any chance that you'll provide a similar benchmark (powersafe vs performance vs ondemand) for AMD CPU in future?

How much power was used in each test? I'd be interesting to know if the powersave options actually increased play time on a laptop running on battery for instance

Once Zen is out I'll probably do some CPUfreq tests if Zen lives up to the hype.

I have some of those numbers in another one of my CPUfreq vs. Pstate articles, but with only having one WattsUp Pro that's often being used, it's not done in all the CPU scaling driver/governor articles.

Great info, thanks

Looks like P-State performance is probably the best default setting for best overall performance.
