Combjelly, Re: "In general, the more layers, the more compact things can be. With modern chips, wiring everything together becomes a massive chore. If they had used less metal layers, then they would have had to make the die larger so that there was room to route everything..."

Extra layers also means extra steps in the fab, which increases manufacturing time, limits total capacity, and increases cost.
