Actually AMDs mobile parts are pretty good at idle power consumption and so are their desktop APUs. Their normal CPUs, which use the chiplet design are rather poor when it comes to idle power consumption. Intel isn’t really any better when compared to the monolithic parts at idle and Intel CPUs have horrible power consumption under load. Their newest CPUs are better when it comes to efficiency than 13th and 14th gen CPU, bus still don’t match or even exceed AMD.

MW/h

Why? Even 1080p is more than what is usually needed for such a KVM solution. It is not like this is meant for doing remote work on a computer or anything like that.

I wouldn’t run it as a router due to its high power consumption, but it would be a fine computer for retro gaming for games up until ~2005 if you add a graphics card.
