The top-end graphics cards have the same speeds in the second test. The GeForce 7900 GTX isn’t much worse than the Radeon X1900 XT; the gap isn’t bigger than 10% at worst.

The multi-GPU tandems behave much alike to themselves in the first test, but the GeForce 7900 GTX SLI looks somewhat more confident in the 8x FSAA + 16x AF mode when earlier. It even overtakes the opponent in 1024x768 and is no farther than 9-10% behind it in 1600x1200. It’s logical to assume that such results are due to the small size of the scene that puts a smaller load on the memory subsystem.

In the third test, on the contrary, the Radeon X1900 XTX and the Radeon X1900 XT CrossFire claim a victory among single-card and multi-GPU solutions, respectively. Note that it’s in the third test that the difference between the GeForce 7900 GTX and the GeForce 7800 GTX 512 is the smallest, so once again the unknown factor we have referred to above is at work again, limiting the performance of the new graphics card. Moreover, the third test scene is large, so its speed depends more on the graphics memory performance than in the two previous tests.

The results of the new graphics card from Nvidia are confirmed in each separate test even with enabled full-screen antialiasing. The GeForce 7900 GTX is nowhere in the lead, but never falls too far behind the ATI Radeon X1900 XTX, either.
