Default ATI Radeon HD 4670 CrossFireX Performance Review

The CrossFireX tandem boasts superb scalability: the average performance gain over the single Radeon HD 4670 is 85%. The frame rate even occasionally grows up by 100% and more, like in Devil May Cry 4, Prince of Persia and Mass Effect – without any degradation in image quality! The only exception is Red Alert 3 where the performance gain is only 15%.

Comparing it with more advanced single-chip graphics cards, the Radeon HD 4670 CrossFireX enjoys an average advantage of 7.7% over the Radeon HD 4850 and 14.5% over the GeForce GTX 9800+. It loses but few tests to them and by no more than 9%, excepting Red Alert 3 where the CrossFireX tandem has serious problems with scalability. On the other hand, it is not as much faster than the mentioned single cards as to justify your replacing them with two Radeon HD 4670 cards, especially as the new recommended price of the Radeon HD 4850 is a mere $129. However, purchasing a second Radeon HD 4670 for your graphics subsystem is a good and inexpensive way of increasing your computer’s graphics performance if your mainboard supports CrossFireX technology.

excellent review, but recommending SLI/CF is never good, especially performance/price wise; only 7% faster than HD 4850 in best case? no thanks
