According to rumors, ATI is working on a dual version of the Radeon HD 5870, but the biggest obstacles to creating a video card Radeon HD 5870 X2 are the power of this card and its cooling system.

Power consumption of current engineering version HD 5870 X2 is 376Vt, and now AMD is actively working on this problem. Perhaps the manufacturer will have to slow down the graphics core is quite in order to reduce the heat to an acceptable level.

Even when using the Radeon HD 5850 cores with a low frequency, which work on 725MGts, energy consumption will fall only on 36W to 340Vt (2x170Vt). Currently, the hottest graphics cards on ATI chips is the HD 4870 X2, which is energy 286Vt. To release a video card Radeon HD 5870 X2, ATI need to reduce energy consumption to at least 300W. But who knows, perhaps, ATI will dare to release hot model 300W.
