ATI Radeon X1800 review: ATI Radeon X1800

As to performance, the ATI Radeon X1800 XL does not differentiate itself as much as the Radeon X1800 XT did from its direct Nvidia competitor. Where ATI's and Nvidia's highest-end cards differ by 22 percent in frame rate scores on our highest-resolution 1,600x1,200 Half-Life 2 test (in ATI's favor), the Radeon X1800 XL separates itself by only 12 percent from its counterpart, the Nvidia GeForce 7800 GT . That's still a decisive victory, but given that the Doom 3 scores at 1,600x1,200 differ by 22 percent to the GeForce 7800 GT's advantage, it's harder to recommend the ATI Radeon X1800 XL specifically for the Direct3D tasks that it excels at than it is to recommend the GeForce 7800 GT for OpenGL games such as Doom 3. All of the frame rates are playable, of course, and if you're willing to dial down the resolution to 1,280x1,024 or 1,024x768, you should even be able to leave antialiasing and anisotropic filtering on and still achieve smooth frame rates with the Radeon X1800 XL.
