They are more efficient for sure, but whether or not they overheat is a matter of how much passive cooling that box really has, e.g. the Macbook Airs still have some issues with throttling, I haven’t looked at the specs but maybe they power limit the chips in the imacs at the cost of some performance in order to not hit TJ max, but if that’s the case why not just buy a higher end mbp?
The m series processors don’t really overheat
