We already told you a few times that ATI's next generation graphics will be two chips on single card but ATI has two codenames for it. One and most commonly used was R670 but in the last few months ATI started using R680 codenames.
R680 is nothing else than a different codename for R670 or should we say dual chip card. In middle 2008 ATI plans to introduce R700 a brand new marchitecture so this will be the new chip and not the R680 as some people thinks.
We just wanted to get that behind us.
