Relax folks, this is nVidia that we're talking about, they're full of win.
Whatever architectural changes were applied in Cayman, those don't matter, since it was still made on 40 nm process, we have come to conclusion that it can never be called a generational change. And regarding the renaming or rebranding game, nVidia is innocent since it was AMD who instigate this round of renaming & rebranding. No matter that the chips were having some architectural changes & priced to compete + offering great value to consumers, they have to bear the brunt of original renaming sin.
