Let’s take a look at the results obtained in 3DMark 2001 and 2003 benchmarking sets.

The relatively simple shader 1.1 test indicates an indisputable victory of the ATI RADEON X800XT and even RADEON X800 PRO. They both outpace GeForce 6800 Ultra here.

Here the situation got somewhat worse, I should say. But even here RADEON X800 XT doesn’t yield to GeForce 6800 Ultra.

During shader 2.0 processing in 3DMark03, the leadership goes to RADEON X800 XT and GeForce 6800 Ultra, which run almost equally fast here. A little below is the graph for 12-pipeline RADEON X800 PRO, while the previous generation solutions are all at the very bottom of the diagram.

Well, the first part of our synthetic test session is over. We are through with the tests devoted to texturing speed and pixel shader efficiency.

According to the results of 3DMark test set, the newest ATI and NVIDIA solutions are equally fast, but the more detailed investigation of the matter shows that ATI VPUs, RADEON X800 XT and RADEON X800 PRO, are beyond any competition in shaders involving a lot of mathematical calculations. However, as the texturing complexity of the shader increases, as well as in case of the simple multi-texturing the laurels go over to GeForce 6800 Ultra from NVIDIA.

Now let’s take a closer look at the vertex processors performance of RADEON X800 XT/PRO.
