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.
Previously, we had informed you that the card is set to have a paper launch April 24, and in all likelihood the card will cost around $1,000, though no official MSRP has been released.
