Intel P-State vs. CPUFreq Frequency Scaling Performance On The Linux 5.0 Kernel

CPUFreq powersave yields much slower performance as well in non-gaming workloads, which most of you should know by now. As for the most optimal choices, P-State in either performance/powersave continues running nicely and similar to CPUFreq performance.

P-State continues working quite well, unlike many kernels ago where in some instances CPUFreq performance was much better off... The Intel driver is very mature these days and delivering great power efficiency.

In most workloads, P-State powersave vs. performance doesn't mean much of a difference, if at all.

CPUFreq's schedutil governor sadly is still pretty disappointing and doesn't offer too much value as the newest governor, at least on the Intel (and AMD) systems we frequently test.
