28nm vs 5nm, is what, 3 generations with a 20-30% power saving at each step. ~50% power reduction is something.

Nope, if you compare theoretical Gflops/watt it's probably 30%, but in practice you'll only get maybe 15%. Memory speed is the bottleneck and you cannot get around that. DDR3 had lower latency than DDR6 and only bandwidth is increasing, and you have to ask bandwidth for what?

Sorry, I don't follow. Why would anything be getting faster if we are talking about hypothetically utilising (just) the power-saving gains from newer nodes?

Basically Gflops/watt is not going north of 1 for 32-bit CPUs, so humanity is completely out of growth. This is the end. Game Over!
