ATI Radeon HD 3870 X2 - Fastest Yet!

The R680 designates, in reality, the Radeon HD 3870 X2, which is based on two RV670 GPUs. As we've seen, the history of multi GPU cards is pretty diverse and if this HD 3870 X2 represents a departure from the concepts behind the Voodoo 5500 (the VSA 100 having been conceived to be grouped at least in twos, from the beginning, to produce an efficient card), its goal is reminiscent of the Rage Fury MAXX in 1999; to offer a product to place in front of the high end models of its Californian competitor.

AMD has decided to integrate two RV670s on the same PCB (for more information on the chip refer to the Radeon HD 3850 and 3870 review). This is, without a doubt, to allow the installation of a imposing cooling system and to facilitate the interconnections between the two graphical sub systems. The result is a monster of 26.7 cm in length (longer than the width of a motherboard). This value is identical to what we have on a GeForce 8800 GTX and Ultra, which holds only one chip.
