Although the single Radeon X1950 XTX is a little slower than the single GeForce 7950 GX2, the multi-GPU systems based on these graphics cards behave differently: the GeForce 7950 quad-SLI is again worse than the Radeon X1950 XTX CrossFire by an impressive 1189 points.
The quad-SLI gets closer to the CrossFire platform in the SM2.0 tests – the gap is only 383 points. This agrees with the results of the single cards and is indicative of the fact that the pixel processor performance is not a decisive factor for the SM2.0 tests.
The SM3.0/HDR tests are quite a different story: the Radeon X1950 XTX CrossFire is suddenly ahead here, increasing the lead over the quad-SLI to 1167 points. This is a gap of about 25%!
Once again the quad-SLI system works incorrectly, performing much slower than the single card. There are no problems in SLI AA mode and the quad-SLI platform, as usual, outperforms the Radeon X1950 XTX CrossFire at 8x FSAA but loses to it at 16x FSAA. It must be due to full-screen antialiasing that the data do not agree with the overall scores for the SM2.0 tests.
The same is true for the second test. The only difference is that the single Radeon X1950 XTX equals the performance of the single GeForce 7950 GX2 because the second SM2.0 test doesn’t require a high fill rate as the first test does.
