AMD Cayman info (or rumor)

[Lightman]

So the 6870 seems maxed around 950ish same with the 6850 clocks high to 900ish, so what are they doing to this chip is it going to be the same size or are they adding things to it? I'm curious

There was a rumor Caymann is the biggest GPU AMD has ever made. If you include 420mm2 R600 then it will be close to 2xBarts size.
On top of that it seems like Cayman has a lot more architectural changes compared to Cypress than Barts! Most people are expecting new shader organization + number of other novelties.
