Such video card will likely require a 6pin+8pin power connector. What’s interesting, new Radeon is believed to consume only ~300W of power, while its older brother 6990 consumes up to 450W. The card will possibly utilize Tahiti GPUs, but it’s not certain which model to be exact: XT(2) or Pro. Packed with 3200 stream processors units and 256 texture units supported with 384bit wide memory interface, combined with 6GB GDDR5 RAM, makes this video card quite a performance monster. AMD Radeon HD 7990 (Malta) AMD is also preparing a counterpart for the GeForce GTX Titan and its true direct competitor, the GTX 690. 6400 stream processors allow for this brute power. Compared to the Radeon HD 6990 represents an increase of approx 58%. Nameįocusing on the technical data Radeon HD 7990 video card will provide the computing power of up to 12.16 TFLOPS double precision computing and 3.04 TFLOPS in a single-precision. But will the next generation of graphics cards offer even more power than the 40nm process gpus? As already known, the Radeon HD 7000 series will be manufactured in 28nm building process. The next flagship of top AMD graphics card planned for 2nd Quarter of next year, AMD Radeon HD 7990 is called after the current Radeon HD 6990 which was a great success. Decide for yourself if this is a deal-breaker.Almost all technical data of the next DualGPU graphics card Radeon HD 6990 has likely been unofficialy available. Igor in our German office created some video and performed frequency analysis that you’ll be looking at shortly. I don’t think it’s particularly ideal to have to use v-sync, but there it is. The solution is to turn on v-sync, capping the frame rate and preventing those highly variable loads. The volume and tone of this phenomenon vary according to the task you’re performing, but it was noticeable enough during our real-world game testing with Bakersfield-based volunteers that several asked me to explain what was happening. AMD explained it to me as an artifact of oscillation between heavy and light workloads, where current draw spikes and dips, causing ceramic capacitors and the PCB itself to vibrate. To a lesser degree, the Radeon HD 7990 runs into something similar.
But I was surprised at just how much noise the card’s inductors generated-like, I couldn’t believe an engineer would kick something like that out the door and expect someone to pay a grand for it. Previously, PowerColor sent in its AX7990 6GBD5-A2DHJ Devil13 for us to look at. The Radeon HD 7990’s cooling fans spin quietly-something I was so happy AMD addressed.
Given that the first fan’s blades protrude up above the plastic shroud a tad, you won’t want to put two 7990s right next to each other in a quad-CrossFire configuration. There’s also a metal plate on the back of the PCB. Fortunately, both of its eight-pin power connectors are up on top of the board, so you don’t have to worry about leads extending another inch or two behind the already-long add-in. That’s an inch longer than GeForce GTX 690. Physically, the Radeon HD 7990 measures the same 12-inches long as Radeon HD 6990.
