The ATI Radeon HD 3870 X2 wins even more confidently than in 3DMark05. And like in 3DMark05, the pre-overclocked version of GeForce 9800 GTX from Zotac is but slightly better than the reference card.
There are no speed benefits in the groups of tests, either. The Radeon HD 3870 X2 is not far ahead of Nvidia’s solutions in the first group, but leaves them behind in the second group that uses Shader Model 3.0 and HDR lighting.
The individual tests that we run with 4x FSAA show an effect from the overclocking of GeForce 9800 GTX. The performance gain is about 7%, which agrees with what we’ve seen in the gaming tests. The ATI Radeon HD 3870 X2 is inferior to Nvidia’s flagship single-chip solutions in the first test that depends on the texture processor performance, but leaves no chance to its opponents in the second test.
The Zotac card has a similar performance gain in the first SM3.0/HDR test. In the second test, the gap is only 4%. The Radeon HD 3870 X2 is far in the lead in both tests.
