It’s hard to tell which card is better in the “pure speed” mode, yet the members of the RADEON X850/X800 families seem to be somewhat faster than the GeForce 6800 Ultra/GT. As usual, the GeForce 6600 GT achieves a win for NVIDIA in the mainstream sector, having higher frequencies than its immediate opponent.
The overall standings remain the same in the “eye candy” mode, but we can now evaluate the performance of the ultra-high-end products. The SLI platforms with GeForce 7800 GTX and 6800 Ultra and the single GeForce 7800 GTX are competitor-less, of course, and the latter isn’t much slower than the GeForce 6800 Ultra SLI. Note also that the RADEON X700 PRO overtakes the GeForce 6600 GT in 1600x1200 resolution.
The previous test scene contained a trip on a speedboat along the Half-Life 2 world, but the d3_c17_02 record shows a battle of Gordon Freeman’s robot companion the Dog with a squad of Syndicate soldiers in one of the narrow streets of City 17. The character of the scene being different, the results of the test are nonetheless similar to what we’ve seen above.
The speed ceiling goes at about 88fps here and is easily achieved in all resolutions by the SLI pair of two GeForce 7800 GTX cards. The single GeForce 7800 GTX spots a little short of that mark in 1600x1200. As for the rest of the participating cards, ATI RADEON cards enjoy a bigger advantage over the same-class GeForce cards in the “eye candy” mode than at the “pure speed” settings. Even the GeForce 6600 GT doesn’t make an exception.
