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

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.
