Moore's Law is with respect to transistor counts and has nothing at all to do with performance. Historically speaking transistors and performance were coincidentally related: More transistors helped do more things at once, and tinier transistors ran faster than bigger ones. Now we're at a different inflection point where the transistors aren't shrinking as quickly, but the dies themselves are getting bigger and the chips are growing more complex in terms of 3D structure. There's more transistors in there, but the easy gains in terms of pitch reduction leading to higher clock-speeds are gone. If we'd been on the same track as before you'd have a ~140GHz CPU. Instead you have a 2.9GHz one because physics is a buzzkill. Here's an older article discussing the problem from 2012 but the same trend has held: https://www.extremetech.com/computing/116561-the-death-of-cpu-scaling-from-one-core-to-many-and-why-were-still-stuck https://www.extremetech.com/computing/116561-the-death-of-cp... Transistor counts continue to climb but power consumption, clock speeds and performance per clock have all hit a wall.
