VR Zone shot pictures at CeBIT of a pair of Radeon HD 7970 graphics cards with 6GB GDDR5 memory. This design may be used for the company's next Toxic branded model, and the GPU core clockspeed is anticipated to be 1200MHz or more.
We highly doubt that there's any reason whatsoever to make a graphics card with 6GB's of GDDR5 memory on a 384-bit wide bus, but hey, someone's going to buy it, as more is always better, right? Beyond sporting an insane amount of onboard memory, Sapphire has also designed a different looking cooler and shroud for these cards as you can see in the pictures.
On the top edge of the cards is a re-designed BIOS switch, which is now a push button with a nice blue LED in it. The cards also feature a few diagnostics LEDs spread across the top edge of the card. The power input is via a pair of 8-pin power connectors, so overclockers should hopefully be satisfied as well.
