Just some quick amateurish quetions from a long time lurker:
Given
(a) the current market situation (i.e. AMD still holding the most porfitable and competitive GPUs in most of the market segments) and
(b) the recent reports of GloFo's 28nm process being just a few more months away
Why would AMD not just want to skip their tweeked 40nm architecture in favor of concentrating their engineering resources on designing/building new chips on the 28nm node? Weren't there complex test-structures (early pipe-cleaners?) around for a few months now? What's the point in releasing a half-step 6xxx family in Q4 2010 when you could very well just spend the winter on (cheap-to-develop) 5*90 tweaks - and announce your entirely new 28nm family in Q1 2011 (with availability targeted for Q2 2011)?
I just don't get the point in doing a half-gen upgrade that late in the R8xx lifecycle (or, for that matter, that near to the alleged start of the new 28nm process)? Maybe AMD are just fooling around with us - and are shooting for their real-deal-2400-shaders-28nm-chip directly? What would be the probabilities of this?
As I said: I'm just a naive amateur in this field so I might not get a lot of important points - but all those rumours of AMDs new R9xx family still being produced on the 40nm process don't seem to add up very well in my eyes.
Hell, they could probably even start their new lineup with a not-that-complex 28nm 67xx chip to "get used" to the new process - and it would still be better than most stuff they could possbily come up with using the old 40nm node?
