Official HD 2900 Discussion Thread

Dont expect anything but around 1950pro performance +DX10. 8600GTS didn´t show wonders either. And it will have the same 128bit bus as the 8600GTS, while the x1950Pro got 256.

If the x2600 uses a similar ring-bus as the x2900, and has 4 memory chips rather than 8, and still uses one ring-stop for 2 memory chips, it would be more efficient than the x2900, thus making up for the large drop in bus-width.

I wouldn't hold your breath on it tough.

There is another difference between 8600-8800 and the 2600-2900 relation. The 8800 has 6 shader clusters of 16 shaders each (96 shaders). The 8600 has 2 shader clusters of 16 shaders each (32 shaders). However the 2900 has 4 shader clusters of 16 shaders each (64 shaders), but the 2600 has a total of 24 shaders total. Apparently it has 2 shader clusters of 12 shaders each, or possible even 4 shader cluster of 6 each. The reduction of shaders in the shader cluster has an impact on the performance, positive or negative I do not know. It could also be so small it's unnoticeable....
