First-Person 3D Shooters
The speed of the GeForce 7800 GTX is so high in Doom 3 that the SLI configuration based two such cards hits against the 100fps frame limiter this game imposes on single-player maps. In higher resolutions, however, we can see that the new graphics card is ahead of its predecessor, probably due to higher frequencies.
The GeForce 6800 Ultra SLI configuration is faster than the single GeForce 7800 GTX just because it has more texture-mapping units.
There are no changes in the ranks after we enable anisotropic filtering and full-screen antialiasing: graphics configurations with more ROP units and with a higher memory bandwidth look better in this test.
Even though deathmatch maps for Doom 3 don’t have any frame-rate limiter, the fastest graphics solutions seem to be limited by the performance of the system at large in 1024x768. The multi-GPU configurations are leaders in both “pure speed” and “eye candy” modes, but the GeForce 7800 GTX is always ahead of the GeForce 6800 Ultra.
