AMD Ryzen 7 PRO 6850U: ACPI Platform Profile Low-Power vs. Balanced vs. Performance

For the most part, the results are exactly as one would expect... Setting the low-power mode will lower the power draw but at much reduced performance. The performance mode delivered some uplift over the out-of-the-box balanced mode.

For scenarios where the low-power mode is sufficient, the performance-per-Watt advantages can be compelling.

In this Xonotic test case, the Ryzen 7 PRO 6850U SoC power draw dropped from a 18.7 Watt average down to 11.7 Watts, a peak of 12 Watts compared to 25 Watts in the balanced mode.

So on a performance-per-Watt basis, the low-power mode can look very good assuming the performance isn't impaired too much that it reduces your productivity or makes games unplayable, etc.

Obviously this helped the thermals too....

it was similar across all of the gaming and graphics benchmarks carried out.
