|Re: At that die size the cost is about $3 on 45nm. But you were noting the difference between 45nm and 32nm so the difference would still be under a dollar. Test and packaging are mostly indifferent to feature size.|
Premium pricing for 32-nm Atom wouldn't have come from saving $1 on production costs. At 32-nm Intel could have added two more cores and still had a smaller processor than 45-nm 87mm^2 Atom, or they could have added more speed grades while keeping TDP constant, or they could have charged a premium for lower TDP versions of the same speed grades. But as I said before, apparently AMD and Intel feel that whatever pricing premium they could have collected from cutting edge budget processors wasn't worth the cost of doing so.
