Compiling the Linux kernel while toggling the EPP values didn't help gain any faster build performance but the power-saver mode did lead to around 10 Watts less on average during the code compilation process.

Programmers on the go frequently compiling code may want to try the EPP power-saver when on battery to extend the Meteor Lake laptop battery life.

For those using the FFmpeg multi-media library for live-streaming or other purposes can get some nice performance gains from EPP adjustments or extending the battery life nicely otherwise.
