AMD Rembrandt CPUFreq vs. AMD P-State Linux Testing
For the developers out there, here are some code compilation benchmarks with this Lenovo ThinkPad X13 Gen3 powered by the Ryzen 7 PRO 6850U.
The amd-pstate schedutil configuration again was the outlier with delivering much lower performance than the rest...
Though if wanting to extend your battery life, the amd-pstate schedutil had an average battery power draw while compiling the kernel of 16.5 Watts compared to 24 Watts with the other configurations. A 23% longer build time for a 32% reduction in battery power use.
Surprisingly with the Godot and Mesa timed compilation benchmarks, amd-pstate schedutil matched the leading performance of amd-pstate with the performance governor.
For some Node.js testing from the laptop, using the amd-pstate performance and acpi-cpufreq schedutil governors was leading to the best performance-per-Watt.
