Interesting point there. The question is, could AMD react? I expect GK110 to be at least 40% faster than GK104. According to some it will be a bit above 500mm2 and pack 6bn transistors. Bandwidth would also be considerably higher. It would be a bit like GF114 vs GF110.

But I admit that it takes time to get a product ready for launch, even if the chip is ready. Maybe Nvidia wants to be first with this "refresh". However, they could just clock GK104 higher, they have more headroom in regard to TDP.
