In 2013 Nvidia plans to launch a Maxwell chip and Jensen just told at the press conference that the new chip is 40 times faster than Fermi and that it will get up to 10 to twelve times faster than Kepler.
The manufacturing process of choice is 22nm, something that TSMC hopes to have in 2013 but it still leaves quite a gap in 2012 when there won’t be anything really new, just maybe a tweak in Kepler.
This is a long time to wait for a new architecture, but at the same time it's all about the FABS that simply won’t be ready. 28nm only comes in 2011 and until 2013 we will be stuck with it.
