One of the German internet services came to information on the new ATI graphics processor, for which they are to be based new, high-endow graphics cards from this company. Announced the RV770 Pro GPU and RV770 XT, and will be on board the Radeon HD 4850 and 4870.

RV770 Pro will likely strong 650 MHz clock from shading units operating at a speed of 850 MHz and 1728 MHz memory GDDR5. The RV770 XT are to have strong GPU at 850 MHz (shadery @ 1050 MHz), and memory – 1935 MHz GDDR5. It is interesting, because so far the ATI graphics chips have the same strong GPU and shader. Now clocks will be distributed, just as is the case with NVIDIA graphics processor.

RV770 Pro and XT will have 32 units teksturującymi (TMU) and 16 units of ROP. As for the TDP, in the case of HD 4850 has it out 110W, and more effective in 4870 – 150W.

Prices of new models will probably amounted to 270 U.S. dollars for a Radeon HD 4850 and 350 U.S. dollars for the HD 4870. At the moment, they are difficult to comment as he did not know what will be the performance of these cards.
