According to reports that have cropped up over the past few weeks, AMD is prepping a high-end card dubbed the Radeon HD 3870 X2 for a launch early next year. The card is expected to feature dual RV670 graphics processors—the very same featured in Radeon HD 3870 and 3850 cards—with clock speeds of 750MHz or more and a total of 1GB of GDDR4 memory, all running on one circuit board. In much the manner as Nvidia's old dual-GPU GeForce 7950 GX2 delivered SLI on a stick, AMD's rumored card should allow users to opt for CrossFire on a stick.
A new report over at Legit Reviews now suggests the 3870 X2 will resemble its Nvidia precursor in more ways than one: the report shows a shot of two cards working in tandem in a physical CrossFire configuration. That means users will be able to pair up 3870 X2s to form a quad-RV670 setup—even if they have only two PCI Express x16 slots. Of course, the performance of such a configuration should largely hinge on AMD's drivers, but Legit Reviews says it was able to test Unreal Tournament 3 on a quad-RV670 setup and that "stability and performance were impressive."
