Benchmark Results: Metro 2033 And F1 2010
At high details, the CrossFire-based solution has a clear advantage. But with Very High details applied (in addition to 4x anti-aliasing), the dual Radeon HD 6850 setup struggles to achieve parity with the Radeon HD 6950, and the single card leaps far ahead at 2560x1600.
In this case, we can see 2 GB of graphics memory clearly mattering, although the single card is unable to deliver smooth frame rates at the higher resolution anyway.
At High detail settings, F1 2010 prefers the previous build and its single Radeon HD 6950. At Ultra High quality with 8x anti-aliasing applied, the CrossFire configuration wins the race.
