14 DAY TRIAL // Graphics cards based on AMD's upcoming Radeon HD 6990 GPU really seem to abound at this year's CeBIT as after Gigabyte, MSI and Sapphire, XFX is also showcasing a system that is powered by the soon-to-be-released dual-GPU gaming monster.
Not so many pictures of the card are available right now, but, form the pictures provided by Hardware Luxx, it seems like XFX's version of the HD 6990 is identical to the reference card officially presented just a few days ago.
However, this doesn't mean that the final version won't differ from AMD's reference solutions, but the odds are rather slim as redesigning such a card takes quite some time as well as some pretty advanced engineering.
As you probably know by now, the HD 6990 is based on two Cayman XT cores that are installed on the same printed circuit board and connected via CrossFireX.
This means that the graphics card packs no less than 3072 stream processors, 192 texturing units and 64 ROPs as well as dual 256-bit memory buses with a total memory bandwidth of 307.2GB/s.
The reference frequencies are set at 830MHz for the GPUs and 1,250MHz (5GHz effective) for the 4GB of GDDR5 memory, but AMD's latest creation also boasts a special OC mode that can be selected by simply flipping a switch placed on the board itself.
Activating this mode raises the GPU clock to 880MHz, and AMD says the card has even more left in it as it promises that the cores can go over 900MHz while the memory can exceed 6GHz.
According to the same leaked presentation slides that we detailed just two days ago, the card is cooled by a dual vapor chamber setup and uses a specially designed VRM.
The AMD Radeon HD 6990 will be made official on March 8. A few days later, during the PAX East game conference, Nvidia is expected to launch the dual-GPU GTX 590.
