LegionOfHell,

Since you need to ask, I'll tell you that performance is like switching them both off.
Your CPU will run at its maximum clock frequency all the time and no decisions to limit power use will be made..

Research them both.
Determine where your use case fits in then set them accordingly

well for the ENERGY_PERF_BIAS , the motherboard has it set to performance but the kernel changes it to normal...I guess going with the motherboards option would be a better idea...


As for CPUFreq's performance governor, here is a line I read on Arch's wiki...

"Note: The intel_pstate driver supports only the performance and powersave governors, but they both provide dynamic scaling. The performance governor should give better power saving functionality than the old ondemand governor."

LegionOfHell,

You need to take into account your use case too.

On my own systems I use On demand. On rented servers, in a data centre, I use performance.
