Intel is very likely still the IdleM@ster[1][2].

Also, most CPUs spend most of their time idling or very low load, not belching hellfire upon the scorched earth. Efficiency at idle/low power is far more significant than efficiency at flame belching if power consumption over time is concerned.

Idle power consumption is all over the place with AMD taking the lowest and highest spots on this chart: https://www.reddit.com/r/Amd/comments/10evt0z/ryzen_vs_intel...

Who wins depends on both the system and how it’s used.

I recall this blog post[1], discussed here[2] at the time, discussing how a SATA chip driver prevented the CPU from going to sleep state C6, instead keeping it at C3, leading to higher power consumption.

Switching the SATA card to one with a different chip fixed that.

There were other surprising factors which affected power draw.

My takeaway was that as in real life, sleeping can be hard.

In fact, you linked the exact thing I linked. :P

Oh lol. Opened the links in new tab but didn't read before commenting, classic n00b fail. The "visited" look didn't phase me since I had, as mentioned, read it here before.

How big is the difference on a regular setup? And is it a same kind of cpu, with integrated graphics? One of the example you linked says 7 watt, which is impressive, but I think you could achieve similar optimizations on an amd system. Let's say I install windows or some linux desktop and don't do any optimizations, how big is the difference?
