Performance in Semi-Synthetic Benchmarks
Half-Life 2 Stress Test
This test in fact serves to benchmark the shader pixel performance. The RADEON X800 family GPUs are faster than the GeForce 6800 series chips at executing pixel shaders, so the results are natural. The ASUS V9999 Gamer Edition is but slightly slower than the RADEON X800 Pro, though – about 6-10fps with overall high absolute fps rates. This suggests that the ASUS card excellently handles this shaders-rich test. Overclocking the ASUS card produces a small effect – no wonder, considering the specifics of this test. (One comment: the test doesn’t use Shader Model 3.0, but will probably do in the future, allowing the NV4x architecture to show better results).
The RADEON X800 PRO comes ahead in the eye candy mode, once again confirming its suitability to hard operational modes. Its advantage over the ASUS V9999 Gamer Edition is the biggest in 1024x768 resolution.
There are few sophisticated shaders in Aquamark3, but the scene geometry is complex and the overdraw coefficient is high. Thanks to its fast memory, the ASUS goes neck and neck with the RADEON X800 PRO in the pure speed mode. Overclocking pushes the V9999 Gamer Edition to the level of the 16-pipelined GeForce 6800 GT.
After we have enabled full-screen anti-aliasing and anisotropic filtering, the situation becomes more favorable for the RADEON X800 PRO. The ASUS V9999 Gamer Edition falls far behind the competitor. Overclocking puts the ASUS card higher than the GeForce 6800 GT in the results table.
