The final specifications of AMDs soon-to-be-released Radeon HD 7990 graphics card have come onto the stage.
ChinaDIY has exposed the final specifications of AMD's upcoming Malta HD 7990 graphics card. None of the specifications are particularly surprising, as from the beginning it was already a certainty that the graphics card was essentially two HD 7970s slapped onto a single PCB. Any specifications that have come to light have already been leaked more than once, so the convenience of a repeated sample had us all arrive at conclusions rather swiftly.
First, the card features two Tahiti XT cores that are built on 28 nm lithography. As a result, the total transistor count reaches 8.6 billion. The HD 7990 features 4096 Stream processors, 256 TMUs, and 64 ROPs, all seated half-half on each of the two GPUs. The GPUs' clock speeds will be exactly 1 GHz. The only specification that remains unknown is what the Boost clock speed will be, or whether there will be a Boost clock in the first place. The graphics card also features 6 GB of GDDR5 memory, with 3 GB assigned to each GPU. The memory runs over two 384-bit memory interfaces at 6 GHz.
With these specifications, the graphics card plows through an impressive 8.2 TeraFlops, and the memory carries a shocking 576 GB/s bandwidth. To make all this computing power happen, the card has been equipped with two 8-pin PCIe power connectors, resulting in a maximum total power consumption of 375 watts. It would also support DirectX 11.1.
