Performance in First-Person 3D Shooters
Battlefield 2 still does not support extreme full-screen antialiasing modes, so we limited ourselves to the 4x FSAA + 16x AF mode.
Just as we expected, the GeForce 7900 GT is about as fast as the GeForce 7800 GTX. And this is true for the single cards as well as for the SLI couples. Well, the G70 and G71 chips are architecturally identical whereas the difference in clock rates between the old and new cards from Nvidia isn’t so big as to lead to a significant difference in their performance. Even in 1600x1200 the newer card is only 5% faster.
Curiously enough, the single GeForce 7900 GT is considerably slower than the single Radeon X1800 XT, but two such cards in multi-GPU mode aren’t any worse than the two Radeon X1800 XT and provide over 110fps in the highest resolution.
The Chronicles of Riddick
The GeForce 7900 GT isn’t far ahead of the GeForce 7800 GTX at 4x FSAA, but the gap grows bigger when we switch to the more resource-consuming antialiasing modes – most likely due to the higher memory frequency of the new graphics card. In the SLI AA 8x mode the GeForce 7900 GT SLI is faster than the Radeon X1800 XT CrossFire platform which features better technical characteristics but is far less economical. Anyway, 1280x1024 remains the maximum resolution for all the multi-GPU configurations in which the game runs at an acceptably high speed.
