SLI vs. Crossfire: High Resolution Comparison

jmke · 30th August 2006, 16:17

We're primarily concerned with extreme hi-res gaming here, so we're going to benchmark these cards at two resolutions: 1600x1200 and 2560x1600. We'll test them both raw, and then again with 4x anti-aliasing and 8x anisotropic filtering enabled.

For comparison's sake, we're going to include ATI's Radeon X1900 Crossfire, their previous best configuration, along with a pair of GeForce 7900 GTX cards in SLI. We used two different brand 7900 GTX cards—XFX's overclocked XXX model and eVGA's less-aggressively overclocked version. To maintain stability, we had to clock them at the slower of the two cards' settings: 675GHz for the core and 1.63GHz for the RAM. This is still slightly faster than the reference clock speed of 650GHz and 1.6GHz.
