I'm not claiming anything controversial. Power not having scaled as well as area recently is often referred to as the end of Dennard scaling:

That can be true despite the fact that power hasn't scaled as well as area.

Yep, just not as much as they improved area.
That is simply not true. You can run the 64 Core on EPYC 2 all at once at 3Ghz all with Air Cooling.
At every node they have reduced power consumption that is also one reason you see continuous performance improvement.
