> but it can't get out of it quickly for some reason As overclockers are aware, to achieve higher frequencies but keep CPU stable, one gonna need higher CPU voltage. Works other way too, lowing frequency allows to lower voltage, and that’s what mostly delivers the power saving from these low-power states. These chips can’t adjust voltage instantly because wires inside them are rather thin, and there’s non-trivial capacity everywhere. This means CPUs can drop frequency instantly, then decrease the voltage over time. However, if they raise frequency instantly without first raising the voltage, the chip will glitch. That’s AFAIK the main reason why increasing the clock frequency takes time. The chips first raise the voltage which takes time because capacity, and only then they can raise the frequency which is instant.
