Cpu and GPU technology

Once we reach the smallest possible nm and optimized the ipc as much as we could, pushed GHz to the limit, how do we improve cpu performance besides adding more cores?

 

About GPU, can you add just a very large number of stream processors? Lets say you double the rtx 3080 stream processors, how far will performance scale?

If we knew, we'd already be doing that. In other words, we don't know yet.

Quantum computing is a thing...it's been a thing for a number of years now.

That goes beyond silicon nm sizes...

 

Companies like D-Wave exists.

EDIT: 

Forgot about IBM, too...and a few other big names.

Quantum-computing isn't a replacement for traditional computing. Quantum-computers are good at quickly finding all the possible solutions to a maths problem, but they are not good for executing logic in the way traditional computers are, so no, that's not an answer.

Yes, and quantum computing is still a bit immature, it'll take a long time before we find quantum proccessors in any home.

Various ways to improve performance even without a die shrink.

 

Look at how long Intel has dragged out 14nm :P
