Report: Final AMD Radeon HD 7990 Specifications

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.

    It will likely have the same memory clock as the GHz edition 7970s. I still don't see myself paying 1k for this card though. It should be priced around $800

    Yeah but the real question is, will this be the Titan killer?! Let's see, it's obviously cheaper, BUT more fps!? Stay tuned..!!

    It should be able to produce more fps but whether that will translate to smooth gameplay is another matter altogether.

    first off the guy in the picture looks like a D@()che I3ag...secondly this angers me that AMD waited so long to do what Asus did 6 months ago. I understand that AMD is at a point where they are massively at innovation anything new, now they have ppl who want to show off an already obsolete piece of hardware.....Shame on Nvidia andAMD at this point...Since Nvidia can innovate but charges arm and a leg (GTX titan)...and AMD for not even keeping competitive.....sad...very sad..

    New trend of GPU makers charging $1000 for their highest-end offering is a bit disappointing to say the least.
