1.42857... squared is 2.0408... so you can get a double the number of transistors in the same space moving from 40 to 28nm. That's just over 6.4 billion transistors unless my maths is completely off.

The reduction has to be squared to make it work for a square chip doesn't it?
Yes, you're correct. The other guy's 60% calculation is wrong - you square the ratio, not multiply by two. Learn to trust yourself more
