if you can power them, cool them, and connect them up in a useful way.
Good luck with that. Power costs go up linearly at best with cores if you don't have any more transistor scaling.
- sbierwagen 9y agoPower will always scale linearly with cores, of course, but you could make cores less power-hungry with reversible computing: https://en.wikipedia.org/wiki/Reversible_computing https://en.wikipedia.org/wiki/Reversible_computing Actually useful reversible logic is, as they say, an open problem.
- akuma73 9y agoMy point was that a new transistor shrink would give you lower power vs. the same transistor in previously larger node. You get more compute-per-watt with small transistors. If scaling stops, then all kinds of things get more difficult.
