Performance in Synthetic Benchmarks
The RADEON X800 XL is 868 points behind the GeForce 6800 GT in the overall score, but that’s not too much. Let’s see where this result comes from.
NVIDIA’s cards quite expectedly win the first test – it is free from pixel shaders and uses only DirectX 7 functions. The GeForce 6800 GT is 10-15% percent faster than the RADEON X800 XL.
With enabled full-screen antialiasing and aniso-filtering the RADEON X800 XL overtakes the GeForce 6800 GT.
The second test (and the third one, too) prefers NVIDIA’s cards: the GeForce 6800 GT goes neck and neck with the RADEON X800 XT, the RADEON X800 XL following them about 10% behind.
The RADEON X800 XT and XL have nearly the same frame rates in the “eye candy” mode, but they are both find themselves behind the GeForce 6800 GT. The more advanced memory controller of ATI’s cards helps to improve the situation in higher resolutions.
