ATI RV770 GPUs have 256-bit memory bus

FUD Zilla heard the ATI RV770XT won't have a 512-bit memory bus, the site says it will be 256-bit.
We've posted that RV770XT will be 512 but our usually very reliable sources misinterpreted some parts of the information. The card is 512bit internally as ATI has its internal ring buss memory interface but externally we are talking about the 256bit card.

Both RV770XT and PRO will be the same and they will work with 256bit memory. The RV770XT pairs with 512bit memory and the ultra high speed should help the card improving the performance but from what we know Nvidia’s GT200, Geforce GTX 280 will work with the real 512bit memory controller.
FUD Zilla believes NVIDIA's GT200 GPUs will likely offer big performance gains over ATI's new GPUs but they will cost a lot more.
