Halo: Combat Evolved
Halo is all brimming with pixel shaders, but is using rather simple textures (this shooter comes to the PC from the Xbox console where the amount of graphics memory is limited and complex textures just cannot be stored). Due to these reasons the GeForce 6800 and the ASUS V9999 Gamer Edition deliver about the same speed. Higher GPU clock rates are most rewarding in this game – just take a look at the results of the overclocked ASUS. All in all, the graphics card from ASUS is about as fast as the RADEON X800 PRO in this test.
Effectively executing pixel shaders and complex geometry, the RADEON X800 PRO is considerably faster than the ASUS V9999 Gamer Edition in this game. This is not crucial, though, as the ASUS V9999 notches a result of 180fps in the highest resolution, which is more than enough to play any game. This game also shows the effect of fast memory on performance in high resolutions.
When anti-aliasing and anisotropic filtering are enabled, the memory speed starts to matter even more. The ASUS V9999 Gamer Edition sports GDDR3 memory clocked at 500 (1000DDR) MHz, which allows it going on at the same pace with the RADEON X800 PRO.
