while the yields seam low, this is the should be the 1st batch, and it dosnt say what they wanted. while it sounds like and i would guess is BS, they could have wanted a fully working chip in 40nm and that clocks vary high for a top tier, then that would make sense that they have a reported 2% yeild. NV basses the gpu tiers or getting fully working, and partially working chips, so lets say that they got 2% of the top chip the 1st try that seams good to me.

charlie spins things so if u look at it how i suggest as the logical way for it to be true then it could make sense, there could be the reported 30% or whatever it was then the top chip gets 2%.
