It’s somewhat different in the third test where the GeForce 7800 GTX SLI gains the lead in the 4x FSAA + 16x AF mode. This graphics subsystem is thereafter not as far behind the CrossFire platforms as in the previous case, probably because of a higher geometry-processing efficiency (the geometry of the third test scene is more complex than of the second one).

The Radeon X1900 XT CrossFire proves its superiority over the Radeon X1800 XT CrossFire in the fourth test which provides some room to showcase the increased math1ematical performance, even though the employed shaders aren’t too complex by today’s standards.

As a result, the Radeon X1900 XT CrossFire scores more points overall than the Radeon X1800 XT CrossFire mostly due to the results of the fourth game test. In the other tests the two CrossFire platforms have near the same performance.
