I wouldn't hold your breath that AMD will be leagues better on this front. For instance, the power specs for AM5 don't bode well in this regard when 16C is the top-end for this platform.
As I've probably said elsewhere, this thing called
Dennard Scaling, where like Moore's Law, was an observation that as transistors get smaller, their power density remains constant (meaning more transistors for the same power). And like Moore's Law (at least in its original form), it broke down in the 2010s. I wouldn't be surprised if AMD's next flagship GPU gets a 50W TBP bump.
There's also the issue that most cards are shipped with efficiency thrown out the window anyway in the name of good reviews and stroking e-peens.
