Computex Taipei 2013 - We took a closer look at Sapphire's beautiful Atomic HD 7990 GPU in their room at Computex, and wow does it look great. Not only does it feature two Tahiti XT2 cores, but the cooling system on it is really something else.
There's six miniDisplayPort outputs, for some serious multi-monitor work and the power going into it is quite insane: 12 Phase/50 amp per phase to provide 600 amps total. This is provided by three 8-pin PCI Express power connectors. The water cooling on the Atomic HD 7990 is great, too, with a full copper water block on offer, with an ultra low noise pump and for the reservoir we have a front 5.25-inch reservoir with one pump pre-installed with the option of upgrading to a dual pump system.
The radiator is 240mm and fan wise we have two 120mm fans capable of 1200 RPM.
