I am wondering what can be done in Linux to reduce CPU power consumption. In Windows, I’m familiar with setting and testing power limits and undervolting using Throttlestop (amazing tool), but to my knowledge no such tool (command line or otherwise) exists for Linux.
I’ve recently acquired an HP Mini G6 with a full fat i7 10700, which came as a surprise as it was advertised as 10700T when I went to pick it up.
I was after the T CPU due to the lower power consumption for an always on home server that sees occasional use (media server, file sharing, image backup, etc)
Also, I don’t actually know if the idle power consumption between the 10700 and the 10700T is actually any different, or if the T only prevents the CPU from boosting as hard - if anyone could clear that up! Cheers.
Install powertop. It will allow you to tune the power consumption.
There is intel-undervolt which might already do what you need.
There is also the cpupower utility which works with the pstate driver which allows you to tune the frequency.
