Why do they not make a giant cpu with 10b transistors?

sandybridge-e will have 2.2b transisters, source: http://www.anandtech.com/show/5091/intel-core-i7-3960x-sandy-bridge-e-review-keeping-the-high-end-alive

since it's a tiny chip, and they pack that much into it, why don't they just make a chip say.. 2x as big and pack 4x as much into it?

Maybe because it would be ****-off expensive?

+1 for first post brilliancy.

sure you'd have to watercool the top and air cool the bottom of them, but think about the speeds! Besides, it's only a stupid idea, it took long enough to get processors to a nice tiny manageable size now, why would we want to take a step back?
