Nothing, I'm making this up, except it's been confirmed by pretty much all desktop Zen users:

https://www.reddit.com/r/Amd/comments/1brs42g/amd_please_tac...

I don't bloody care that AMD CPUs seem to be more power efficient than Intel's. For most people their CPUs are completely idle most of the time and Zen CPUs on average idle at 25W or MORE.

Many Zen 4 and Zen 5 owners report that their desktop CPUs idle at 40W or more even without the 3D cache.

I can't confirm the 40W, my Ryzen 9 7900 (non-X) consumes 1W to 3W at idle on Windows 10.

Please post a HWiNFO64 screenshot.

I have reasons to believe you're making this up.

Not a single user has seen such low idle power consumption for desktop Zen AMD CPUs.

Could it be that that some cores are constantly being waked up by something?

I mention that since you seem to be on Windows, which itself has a hard time to just shut up, but that is also easily paired with bad drivers, stupid software and bad peripherals.

I happen to be on Fedora Linux 42 and Windows 11 but my primary OS has been Linux for almost 30 years now.

Idle power consumption under Windows and Linux is exactly the same. Linux doesn't have any magical tricks to make it lower.

Windows has more services running in background but they don't meaningfully affect idle power consumption at all.

The entire Reddit topic confirms my statement, multiple over hundreds of reviews confirm what I said, yet it's

It's kinda hard to be an AMD fan when you live in an alternative reality, huh?

		`> It's kinda hard to be an AMD fan when you live in an alternative reality, huh?` I don't know, as I am not too much intimate with both concepts. I meant to say if both measure idle power but come with different results, are they measuring the same? Could hardware and software differences influence idle power? What values does an "idle power reading" measure actually?

Sure, it's reported by the Radeon Software, but I'll check HWiNFO64 soon and post a screenshot.

52 minutes to post a screenshot?

Guess someone doesn't want to be embarrassed.

Someone flag this comment for insult. I was at work, was taking a break, I wasn't on my personal computer.

		I am treated so unfairly, it's unbelieavable. People with insults get away without punishment, but my innocent screenshot is invisible.

		I posted my screenshot yesterday but it's not visible. I don't care anymore.
