The Leadtek is closer to the RADEON X800 XL in the second test: they already have almost the same speeds in 1280x1024. The overclocked PX6800 GT keeps on the level of performance of the two senior RADEON models.

After we enable full-screen anti-aliasing and anisotropic filtering, the WinFast PX6800 GT is again slightly slower than the RADEON X800 XL in the first two resolutions. In 1600x1200, however, its performance degenerates dramatically. Overclocking isn’t as profitable as in the “pure speed” mode, save for 1600x1200 where it’s important to have a high memory frequency.

Supporting Shader Model 3.0, the WinFast PX6800 GT is a mere 1-2fps behind the RADEON X800 XL. The overclocked Leadtek rivals the RADEON X850 XT. The advanced NV4x architecture shows its benefits here.

The WinFast PX6800 GT isn’t far behind the RADEON X800 XL, its main market rival, in the “eye candy” mode, either. The latter, however, has an advantage in higher resolutions due to its advanced memory controller. Overclocking is profitable in this test: the overclocked Leadtek is almost as fast as the RADEON X850 XT Platinum Edition.

Thus, the results of the Leadtek card in both versions of 3DMark seem on the whole correct.
