3DMark05 differs dramatically from the earlier version of Futuremark’s benchmarking suite as it uses sophisticated pixel shaders in each game test, along with some other advanced graphical technologies. The Sapphire RADEON X1800 XL being based on an appropriate architecture, it enjoys a considerably higher overall score than the GeForce 7800 GT has.
The Sapphire RADEON X1800 XL is a little ahead of the GeForce 7800 GT at first, but the gap between these two graphics cards diminishes to zero in higher resolutions. The load in this test scene comes mainly from the models of the soldiers and from the eight light sources. But maybe the Sapphire card can do better in the other tests?
