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.
Performance in Third-Person 3D Shooters
Lost Planet: Extreme Condition
Alas, CrossFireX technology doesn’t show good scalability here. The 4870 CrossFire subsystem and the 4870 X2 card are hardly any better than the single Radeon HD 4870. You can see that the 4870 CrossFire is even slower than the single card at 2560x1600 (but not at the other resolutions) whereas the Radeon HD 4870 X2 is exactly as fast as the single-chip solution then.
Tomb Raider: Legend
Graphics subsystem with two Radeon HD 4870 graphics cards maintains slightly higher minimal fps rate, which means that Tomb Raider: Legend may be using additional onboard memory to its benefit. A pair of ATI Radeon HD 4870 cards as well as 4870 X2 model are slightly ahead of Nvidia GeForce GTX 280.
