And I don't necessarily agree to your examples in 1 & 2 either. Fermi had 1 or more hw bugs, but it wouldn't had been manufacturable in late 2009 due to crappy yields and in extension too high costs anyway and it's not like R600 had a joyride with 80nm@TSMC which NV for some weird reason avoided completely.
Well my conclusions were based on how well the follow ups fared. Fermi was eventually vindicated, R600 was still slow in RV670 guise.
It's my understanding that their original plan for Kepler was for quite some time to go with the performance part first and later on to go for the top dog.
If that really was their plan I hope they aimed higher this time else they won't have anything to face Tahiti. That's also doubtful because Titan was supposed to get daddy Kepler by the end of 2012 - I assume for that to happen the chips have to be ready well before then.
One message that might be of some value is "earlier than expected". So when was GK104 really expected after all, since no next generation 28nm GPU made it on shelves in 2011?
Summerish?
