RV770 comes in GDDR3 and 5!
 

 
We can now confirm that ATI's single chip RV770 will come in two different versions, the slower of the two being the 770 PRO and the faster being dubbed XT. There is a huge difference between the two as the PRO will be coupled with GDDR3 memory whereas the XT will have the new GDDR5.
 
ATI's partners will be the ones to manufacture the PRO version but the XT will be manufactured by ATI itself and will end up very much the quickest of the two. The new Rx7x0 generation will consist of two single-chip cards and are most likely be called something like 4xxx.
 
But at the moment ATI has yet to decide the official name.
