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 arrives.
