Shader Model 3.0 Game 1

Both a high scene fill rate and a high speed of execution of numerous pixel shaders is important for the first SM3.0/HDR test, and it’s here that the advantage of the Radeon X1900 XT CrossFire is well outlined. The gap diminishes in higher resolutions, from about 30% to 20%. So, the four chips of the GeForce 7900 quad SLI platform obviously have a lower efficiency than the two chips of the Radeon X1900 XT CrossFire in this test.

Shader Model 3.0 Game 2

The second SM3.0/HDR test isn’t as difficult as the first one, focusing on realistic dynamic shadows and HDR lighting. Anyway, the Radeon X1900 XT CrossFire outperforms the GeForce 7900 GTX in all the resolutions here.
