I asked someone who worked on chips a similar question. The density helps connecting the parts. If the nodes aren't near each other, they have to move through other nodes to get from one to the other, and that process is "slow" in the world of chips. I guess it's like trying to get from LA to SF. You could get to SF of you 10x'd the size of earth, but it would still more than 10x as long despite having the same connections because you'd need to stop for some extra connections to even make it.
