I read to "if all goes really well we could" then stopped.
Don't get disheartened, if you read "if all goes really well we could" out of Nvidia's CEO's gob then you can be sure whatever he's promising won't happen... ie "if all goes really well Fermi will be available 23rd November"......
For AMD "if all goes really well we could" has generally turned out to be the case for 30months or so
Its always going to be a hard ask to get some decent parts out for a trade show 2-3 months in advance of retail release, more so on a dodgey 40nm process, AMD will likely be increasing Shader count, meaning a most likely bigger core, which means running into yield problems because of TSMC being such complete turd.
As they increase core size, knowing exactly what clock speed/shader counts they'll get the best yields with today, will be very hard.
Its a tough call on performance, being that they simply know manufacturing better than Nvidia, and have tweaked their design to suit the process unlike Nvidia, they "could" go for a same sized core and get higher yields. But even at 30-35% over Nvidia's 20ish %, price would be significantly increased over 58xx series costs.
I reckon they'll go for something about midway between current 58xx size and Fermi size, slightly tweaked shader, better performing uncore that hopefully takes a little space leaving room for a 20-25% bump in shaders would increase its size but not to disasterous Fermi yield proportions.
I doubt they'd want to go beyond 2.5billion transistors, up fro 2.15, short of Nvidia's 3.1billion transistors. THeres not a huge amount of room for increasing performance.
A "refresh" would be the same core at higher clocks, its not a refresh, its getting significant but not massive changes, even with a massive architecture change, if they stay around 2.15billion transistors they aren't likely to gain more than 5-10% efficiency, more performance costs more transistors.
If TSMC had their 32nm on time then they'd have room from the shrink to go to 4billion transistors and be close to the same size as a 58xx core, at 40nm, they are massively limited on transistor increases.
28nm is a huge drop from 40nm though, and even bigger when you move from a crap TSMC 40nm, to a excellent GloFo 28nm, it looks set to be maybe 2nd quarter next year before GloFo is up and running with bulk 28nm, TSMC is supposedly due for 2nd quarter, but most analysts and industry people think thats BS, TSMC haven't hit a release target for a process in 5 years, and often miss them by 6-12 months, often not getting good yields for a further 6-12 months.
EDIT:- Are we sure the Nvidia CEO promised stock before Xmas and on 23rd November, and also said 2009 when he said that? Maybe he meant 2010
