Provided that the 7800 GTX is in a comfortable environment, it´s able to express its full potential in Half Life 2 even without AA 4x or Aniso 8x. Compared to the 6800 Ultra gains increased logically with the resolution at +33.8% in 1280*1024, +53.6% in 1920*1200, and +46.7% in 1600*1200. Performances were only 17% higher than the X850 XT in the best case. Whether it´s with these adjustments or with AA 4x + Aniso 8x, we can see that the 6800 Ultra SLI is approximately at the same level as the 7800GTX.
With the final adjustments ATI reached the same level of performance as the 7800GTX in 1920*1200. Of course the 7800 GTX SLI can do even better, but we wouldn’t expect any less from this product.
Doom 3
There is no surprise that Doom 3 (here in Ultra mode, with anisotropic filtering 8x) runs much faster with the GeForce 6800 than the Radeon X850. The release of the 7800 GTX helps NVIDIA to go even further with up to 53.7% higher performances. The 6800 Ultra SLI is still superior to a single 7800 GTX because of important performance gains due to this type of technology in Doom3. Results are equivalent after FSAA activation, but it allows NVIDIA to reduce the difference in performance.
