Chipguy -

The Madison is a large chips (about 2x bigger than Opteron) but most of the area is L3 cache (~60% IIRC) and is protected by redundancy. And it is manufactured in a mature 130 nm bulk CMOS process so I have little doubt that Intel can turn these puppies out with good yield and in whatever quantities the market will absorb.

Good observation. And because so much area is sram the normal defect density predictions are likely to be too conservative. Intel will likely get higher yield than predicted by die size alone.
