Here is a (semi)recent paper in Science about the end of Moore's law. As I understand it (but I'm not an expert), Figure 2 seems to give pretty compelling evidence that Dennard scaling (i.e, the phenomenon that historically allowed for smaller chips to run at higher clock speeds without an increase in power usage) seems to have stopped around 2005, and that subsequent speed ups have largely come from in-chip parallelism.

That’s what I was taught back in school, the end of Dennard scaling pushed the industry to multi-core, as well as huge temporary power limits to race to the finish as needed for better average efficiency. IIRC the current power density for modern chips is near that of a nuclear reactor.

Edit: yep, this was the source of the claim, slide 4: https://www.glsvlsi.org/archive/glsvlsi10/pant-GLSVLSI-talk.... A 3090 will spike to 500W+ which ends up being ~80W/cm2
