I don't believe that's true, regardless of what you mean by "can run at a power envelope". The M1/M2/M3 use 20-25 Watt at peak, but only 10% of that when idle.

I don't believe that's true, regardless of what you mean by "can run at a power envelope". The M1/M2/M3 use 20-25 Watt at peak, but only 10% of that when idle. (But that's only in the notebooks – it goes beyond that in the Mac mini.) The M3 Pro is basically 50% more of everything than the M3, so I'd reuse that multiplier to guess its power levels.
