Radeon HD 3870 X2

ATI R680: the Rage Fury MAXX 2?

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 our Radeon HD 3850 and 3870 review->,2-447.html]). 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 then 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.

Its weight breaks new records, going a little over the kg and yet, AMD thinks it’s good to highlight in its documents the weight optimizations brought by the use of a hybrid copper - aluminum sink.
