There's still a big problem with just upping the speed. If we have a chip running at 1THz then in each clock cycle light can only travel 3mm.
Moving to more complex 3d chips could help improve performance, but there are limits to the number of dimensions we have too.
- eloff 12y agoYeah, I don't think 1 THz is achievable, but we can likely do substantially better than 4 Ghz, even when we can't go smaller. Then there are also gains to be made from building bigger, building in 3 dimensions, decreasing waste heat, etc. I suspect that innovation with chips will get bumpier, but likely overall maintain the pace of innovation for a couple decades more - which is all we need to get into really interesting territory re AI and other things.
