The sixth-generation ATI Radeon series has mirrored the release of the third-generation Nvidia GeForce – having been scheduled for a Q4 2006 release, the highly anticipated R600 is coming out in Q2 2007, half a year after its main opponent. Will the R600 be a new R300 or follow the fate of the NV30? Let’s check it out right now!
Performance in Theoretical Tests
Scene Fill Rate
ATI Radeon HD 2900 XT behaves just according to theory: its scene fillrate is a little higher compared to Nvidia GeForce 8800 GTS due to increased clock-speed, however, it cannot compare to the 8800 GTX model, as the latter has 24 render back ends, whereas ATI’s new solution only sports 16 of them. Obviously, the R600 cannot match G80’s capabilities when it comes to Z pixel rate, as it only can compute 32 pixels with Z-value per clock.
