Why would I want this? With a properly configured kernel, Intel chips can downclock to somewhere in the 400-800mhz range when idle.

iirc a lot of Intel chips (12th gen+ esp) can be slightly undervolted to achieve better power efficiency and lower temperatures with negligible impact to clock speeds. particularly useful on laptops, mini PCs, and desktops that spend a lot of time at idle.

Where can I find out more about this? Just picked up an i5 13500 and my primary concern is low power usage.

Basically the same as overclocking; set, test, reset, retest ….

Be careful with the verification runs as they can easily eat up the energy savings that you are trying to archive

Check here:

it seams -100mv - -150mv is the maximum (maybe not stable) undervolting.
