Sapphire wants to show off, it appears, with its new Radeon HD 7990 Atomic graphics card. It was first unveiled at Computex, but the details were scarce at the time. Now, however, there is more information on the graphics card, and it seems that Sapphire has put all its knowledge into designing this graphics card.
The card use have two 28 nm Tahiti XT2 GPUs that will be hooked up to a total of 6 GB of GDDR5 memory. The processors will be placed on a black, custom 12-layer PCB that will house an impressive 18-phase VRM that gets its power from three 8-pin PCI-Express connectors. Each of the two processors will have its own 6+2+1 phase power supple for Vcc, VDDCI and MVDD, along with two sets of BIOS' for each of the processors. The PCB will also house six mini-DisplayPorts, which should be sufficient for pretty much anyone. Sapphire claims that the card will be able to run a CrossfireX configuration with any 7900 series card aswell.
The cooling will be provided by a full-cover water block that is hooked up to a 240 mm radiator, which is cooled by two 120 mm 1200 RPM fans, and a reservoir+pump combo to get the water flowing.
There are currently no details on clock speeds, pricing or a launch date, but I will keep my eyes and ears open in case Sapphire announces anything new about the Radeon HD 7990 Atomic.
