Report: Final AMD Radeon HD 7990 Specifications

By - Source: ChinaDIY | B 22 comments

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.

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.

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

    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.

    Considering that Titan is slower than two HD7970s in CFX and cost as much as 3 HD7970s, it will be.

    If AMD keeps working on the latencies in their drivers, hopefully. They have made great progress but haven't even done a beta driver since 3/19 which worries me.

    Another weird tid bit here, the Pixel fill rate and the Texture fill rate are wrong for the HD7970 GHz editrion. The GHz Edition does 32 GPixels/s and 128GTexels/s. My Vapor-X does 33.6GPixels/s and 134.4GTexels/s so it makes me want to not truly trust the source.

    typo in the first sentence: "ChinaDIY has exposed the final specifications of AMD's upcoming Malta HD 7790 graphics card." .....thought this was the 7990?

    The latency fixes are not what worries people. It is the lack of frame metering in crossfire which makes their multiple-GPU setups stuttery unless you use a FPS limiter of some sort.

    That is cool and all but what about game that bug out or don't work with/like Crossfire?

    I could have swore that pre-launch AMD stated that the MSRP was going to be around $750 - ~$800. Things may have changed, but I hope not.

    For reference..a PS4 = 1.84 compared to the AMD 7990 = 8.2

    People say the card is too expensive, but they will sell as many as they manufacture. You can be sure of that. This is gfx card porn.
