I was just reading the news and I came across this article about the new 45nm Intel Penryn.

Two-Storey building eh?
Well the gate size on the penryn is 45nm, and the chip is 107mm^2 (approx 1cm by 1cm).
If we look at what chips were in production 20 years ago (1987).
You'll see that a 1988 486 had a 1um gate size (1000nm).
So the gates were 22x bigger. So the die would be roughly 22cm x 22cm.
Hardly the size of a house
