All about the return
Going off the numbers in my second post. That would mean that Nvidia could have around a total of $564,200,000 in total sales for GK110. That would mean that given a 50% failure rate, they'd be losing out on only $20,832,000 in die costs. That's not factoring in that AMD is going to be running into close to the same problem. And a 50% yield per wafer is quite low estimate in terms of yield per wafer. Most of the time, from what I've been reading around, its generally hitting the 65-75% mark, even with larger dies. Yeah, at 50% yield, that is a loss of $560,200,000 in total sales, but they never were going to sell them, since those were defunct dies that were destined for the trash, and are never going to be used in making a GPU. AMD will run into the same problem.
You are very true in that every GPU counts, but both sides have to make contingency for yields in selling dGPUs. And that is generally factored in already. And what goes for Nvidia in terms of die yields, is going to be nearly the same as AMD. So its really, in the long run, is a negligible difference between the two.
