TDP rating != wattage consumed. In an ideal world it would, but it has long since stopped meaning that generally. This includes the M1, which will happily exceed 15W of power consumption, and the 5850U almost certainly does as well since AMD's previous generation CPU in that class happily exceeded 15W.

You'll have to wait for a proper review that does power measurements to get a sense for how they actually compare on that front.

I agree, it'd be fairer to compare wattage at peak load. Notebookcheck indicates 40W for AMD and 30W for M1, so I guess the perf/watt is closer between the 2 chips.

One could perhaps conclude from those stats though that if it were limited to 30w (i.e. same as M1), that it would still edge out on performance.

My only question is what it's idle power consumption is like.

https://singhkays.com/blog/apple-silicon-m1-video-power-cons... has a writeup of power consumption for certain tasks on the Mac Mini M1 (not written by me).
