The Doom3-based Quake4 benchmark runs do an excellent job of showcasing our previous point of how favorably NVIDIA hardware runs on this engine. Much like the advantage the ATI cards held in Half-Life 2, the NVIDIA cards run away with this benchmark at 1280x1024. Here, the cheaper GeForce 7600 GT commands almost 20fps of headroom over the Radeon X1800 GTO. The more expensive GeForce 7900 GT goes a few steps further by nearly doubling the score of ATI's latest card. Adding FSAA and AF brings an enormous performance hit for all cards and levels the playing field between the GeForce 7600 GT and the Radeon X1800 GTO.
With a higher resolution of 1600x1200, we witness one of the rare occasions where the Radeon X1800 GTO is unable to surpass the GeForce 7600 GT and is still well behind the slightly cheaper card. Again, adding FSAA and AF levels the playing field and the two return nearly identical results. Once more, the GeForce 7900 GT's $50 price premium seems to pay off in spades as its scores are always 15fps or more beyond the other contenders.
