Radeon HD 4870 X2: The Fastest Single Slot Graphics Card!
The guys at Rage3D have spent a lot of time to test the Radeon HD 4870 X2 with around 16 different games. The 4870 X2 is based on the the R700 GPU (actually two RV770). And their conclusion is clear: the Radeon HD 4870 X2 is the fastest card at this point in time. They also recommend, if you have the choice, to buy a Radeon HD 4870 X2 than two Radeon HD 4870 in Crossfire. And last point, an important advice is to have a fast, very fast CPU in order to fill the 4870X2′s command buffer (read send enough graphics data to the card).
Good things come in pairs
This test is focused on DirectX 10 and DirectX 9 titles and it’s a pity that Rage3D has not tested the 4870 X2 with OpenGL applications.
