ATI Radeon HD 4870 X2 graphics card is the fastest solution in the market these days. However, it is pretty expensive and the card itself is so large that may not fit in some system cases. Today we decided to discuss the performance of two ATI Radeon HD 4870 solutions - from VisionTek and Club 3D - in order to determine if a CrossFire tandem like that could become an alternative to the top-of-the-line ATI Radeon solution.

We minimize the CPU’s influence by using the Extreme profile (1920x1200, 4x FSAA and anisotropic filtering).
2 gigabytes of onboard memory are a factor, and the Radeon HD 4870 X2 performs better than the Radeon HD 4870 CrossFire.
Thanks to fast memory the Radeon HD 4870 CrossFire is superior in the first test, enjoying a 20% lead and leaving no chance to the GeForce GTX 280. The gap grows wider, to 35%, in the second test due to the higher efficiency of ATI’s texture processors that are also clocked at a much higher frequency than those of the Radeon HD 4850 CrossFire.
