Fudo reports that AMD's upcoming RV770PR will only support a 256-bit memory interface, and GDDR3. The RV770XT will have a full 512 bit memory interface and support GDDR5.

It looks that the current GDDR5 design sticks with 512-bit memory interface and that RV770PRO will use 256-bit GDDR3 memory. The RV770PRO will need a smaller cooler, as it is definitely going to end up the cheaper of two, and you can bet on a sub-$200 price.

 
RV770 1.5 Times Faster Than RV670? PDF Print E-mail

Fudo says that the RV770 will be up to 1.5 times faster than the RV670. That is quite a bit.

In the real world, this should mean that if one game gives 50FPS with RV670 that the new chip should be able to get you around 75FPS at the same settings. On average, the new chip will have to be at least 30 percent faster than the old one to make you even consider it, but at least specification-wise there is not anything that you might miss.

Fudo says that the RV770 based GPUs are mostly simple die shrinks with minor changes to the design. There should be pretty good power improvements.

The new GPUs are 55nm and they are actually an architecture shrink chip with minor architectural changes. Of course, just as RV670, they do support DirectX 10.1 and at the same time, they will bring some significant performance improvements compared to the previous RV670 generation.

Fudo talks about the RV770 supporting both GDDR5 and GDDR3.

We’ve learned that ATI's single chip RV770 card comes in two flavors. The first and slower one is branded as RV770PRO, and it will be using GDDR3 memory. ATI will let its partners build them and, of course, these will be the more affordable of the two.
