The Tahiti XT graphics processor is currently the fastest GPU on the market, but all signs are pointing to this being a short lived victory for AMD. The word is Nvidia’s Kepler architecture is going to handily outperform any Tahiti based graphics cards, and even two to three months prior to launch the GK104 chip, is looking very polished, though there could be some issues with availability at launch.
The news comes way of SemiAccurate, who got their hands on two Kepler based graphics cards. While was sparing on the details, what we do know is the video configuration consists of dual DVI links, one HDMI output, and a single DisplayPort connector. Additionally, the PCB includes eight on-board memory chips, giving the card a 256-bit memory bus; each memory module is 256MB, which equates to 2GB total.
Other than these rumors, little is known about the graphics card, but more details should trickle out as we get closer to the March/April launch.
