As AMD's new flagship, we see that this is not the HD3870 X2 version of the card, but by the manufacturers Shuangmin pathway offered by Promise high-end graphics, Shuangmin abandon the whole public review board cooling design, but chose to install two separate open-core radiator and thus better cooling effect:
NVIDIA and the 7950 GX2 different HD3870 X2 is not a pair of PCB design, and graphics length is not an exaggeration, and the size of its opponent's top graphics 8800GTX/Ultra is almost the same, so you need not worry about whether installed in the chassis of problems.
Dual fan can easily solve two core of 16 memory and a PCI-E chip heat control, and noise than the high-power version of the single turbofan lower, but shortcomings in the residue is still hot air chassis, the chassis This gamers to a higher cooling ventilation requirements.
Basically, it is fitting the two HD3870, independent power supply modules, needs two 6 Pin PCI-E power supply interface, occupying two PCI slots, as this high-end graphics card is not an exaggeration.
From this perspective, we can see clearly that R680 with a modern 0.8 ns GDDR4 memory, each core opposed to 512 MB 256Bit, the card is 1 GB 512Bit. In addition the center of the card is PCI-E controllers, two RV670 core through its link up to share data and exchange PCI-E 2.0 X16 interface.
