Testing The New ASUS Platform Profile Support In Linux 5.15

It tended to just be in the heavily threaded workloads was there any measurable difference from the ACPI Platform Profile modes but for single or only lightly threaded workloads including games there was minimal difference to the raw performance or power efficiency.

Looking at the CPU power consumption across the span of the dozens of benchmarks carried out, running in the quiet profile mode did lead to a 47 Watt average for the Ryzen 9 5900HX compared to 59 Watt average in the default balanced mode or 62 Watts in the performance mode.

When looking at the CPU temperature overall for the course of all the runs, there wasn't too much of a difference on average.

Other component temperatures like the GPU and NVMe drive were warmer in the quiet mode due to keeping the fan speeds lower.

For those interested in seeing more of the individual raw performance benchmark results and all of the other per-test thermal and power monitoring, see this OpenBenchmarking.org result file for the look at the data from this ASUS ROG Strix G15 Ryzen 9 5900HX laptop on Linux 5.15. Hopefully this testing from the modern AMD laptop offers some insight for those wondering whether it's worthwhile messing around with ACPI Platform Profile settings on Linux but of course the actual effectiveness is highly variable upon the particular laptop model and various design factors.
