ASUS Zenbook S 16 UM5606WA Platform Profile Impact On Performance & Power
With Google Chrome web browser use the performance mode didn't help increase the performance in JetStream 2, but the power saver mode did lower the performance...
But as you can see from the results, the power-saver results saved around two Watts on the SoC power use and in turn led to a nice bump in power efficiency.
This also led the Ryzen AI 9 HX 370 to running significantly cooler than the default (balanced) or performance modes.
For code compilation work there wasn't a big difference but with slightly faster build times in the performance mode and slightly longer build times in power saver mode... Still the power saver mode can be worthwhile if running frequently off battery life.
For demanding multi-threaded workloads like Blender the different options didn't equate to much of a difference.
