ATI is working on a brand new set of a mainstream chips that should be based on the R700 design. We don’t know much about them, but according to current plans, ATI plans to make the R730 a mainstream part and the RV710 an entry level part and these chips should be ready by Q4 2008.
We are still a year away from these products, but bear in mind that ATI plans a February refresh with the RV635 and RV620 and the brand new RV7X0 designs should come out in some six months after the new refreshed mainstream cards.
The game is on.
