re: <GDPW reduction vs. die size>
It's a simple matter of probability. If the probability of an area of the wafer of size X having no defects is 70%, the same probability for an area 2X is only 49%. So the good die go down by more than a factor of 2 as the die size doubles.

Or to put it another way, yes, there are exactly as many defects on the Smithfield die as on the Prescott die. The first order assumption is that each defect kills 1 CPU. But the Smithfield die has <50% as many CPUs on it to begin with, so a greater percentage of CPUs are killed.
