Nvidia has serious yield problems with the GT200.

He doesn't have one, he just defends Nvidia whether right or wrong.

Dude, seriously though, you might be right about some things, but you're trying to argue against people who have real world experience in this field and have spent years studying it? Nvidia doesn't always make the right decision! This is why Intel pays top money for fab experts to improve yields even slightly because the difference is HUGE between a few defects per die area and that means huge differences in profits and margins. Laws of physics are laws of physics and when you manufacture off a wafer, often the same procedures are used. I'm sure they did this analysis before hand, and since TSMC doesn't state their defects per area its speculation, but it's probably pretty safe to say they aren't doing better than Intel and even in that best scenario, the yields are still < 40&#37;. A doubling of defects / cm^2 and you can see yields drop into the 10% or so. Things are exponential when you deal with area, so its not just 1-2% differences we're talking about here.
