Back in the late 90s at Intel, one of the component engineers on our project, who later became an engineering Fellow, had a presentation he was taking around the company explaining the physics of frequency on power density and what this meant for the future. He had a slide with a graph of clock rates (x) and power (y) projections for process roadmaps, with a line going up to a point of practical max of 5Ghz, and then continuing on to the top-tight of his graph where there was a point labelled—in all seriousness!—"Surface of the Sun".
I never saw the whole presentation but when I recall that slide, I laugh at the goofball antics of extreme overclocking with these super-cooling gimmicks and how nonsensical these games are. The industry understood all the tradeoffs long ago, and there's no sane belief that some as-yet undiscovered property of the universe is gonna break the rules of power density.
These physics are why component power stabilized generations ago, with all the new gains coming from clever rearrangement of the core/cache logic. And let's not put them down: these gains have been substantial! But don't keep hoping for any free lunch.
I can't say loudly enough that Apple deeply internalized all these understandings with AppleSi and is taking very meaningful and intelligent steps to arrange how power gets applied to work that product buyers care about.
Intel and AMD are still beating an older drum of sheer gains to be relevant. Intel understands these games very well, and the PC market is structured to play them. The business back-end/server space speaks a completely different language of performance, which any systems enthusiast is wise to investigate.
If you want to see a case study, look into how the server market regards SSD Trim. It will expand your mind about the true properties of this niggling, weird, little storage feature.
To understand 13th gen, note that today American muscle cars still sell, but all the manufacturers know that EV are the future. And what's most notable about Teslas is how they're trying to get rid of the driver!
