Has a new memory controller ATI's upcoming high end card codenamed R7xx, the one that we call R700 is codenamed Wekiva. We don’t know what that actually means but according to google this can be a town or a river in some national park in Florida.
ATI was known by very funky codenames including R520 aka Fudo and R600 without a proper codename but properly delayed.
Wekiva from all we know has a multi chip approach and has a new better memory controller. We can also add that it comes in Q2 2008 so we still have some time to enjoy until it comes.
