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

It's been a while since last running any P-State/CPUFreq frequency scaling driver and governor comparisons on Intel desktop systems, so given the recent release of Linux 5.0 I ran some tests for looking at the current state of affairs. Using an Intel Core i9 9900K I tested both the P-State and CPUFreq scaling drivers and their prominent governor options for seeing not only how the raw performance compares but also the system power consumption, CPU thermals, and performance-per-Watt.
