power I believe uses the powersave governor, which will limit max all cores sustained cpu frequency to ~1600MHz from what I’ve seen. This is also what the battery saver profile on Windows does, from what I’ve seen.
Up to the individual on what they value, though, and one can create a toggle to switch between governors or install one, or use something like auto-cpufreq, etc.
