Answer 1

While some comments touch on the topic of distance and latency, I really want to press the importance of this point. If you get too large then the latency gets to the point where it’s difficult to synchronise across the chip. If things aren’t in sync then it’s not going to function.

Answer 2

bigger chips would mean the sizes of certain other parts in a PC needs to be changed as well.

i already had a hard time when switching my 1060 to a 2080 due to their size difference

Answer 3

Costs and distance.

The closer 2 parts of physically the faster it can be which is something people forget.
