ATI FirePro V9800 workstation graphics card drives 6 HD monitors with 4GB frame buffer
AMD rolled out the ATI FirePro V9800 which features a 4GB GDDR5 frame buffer and six mini DisplayPorts to drive up to six HD displays. AMD is clearly targeting a new market focused on low-cost video walls for design/review, large volume data sets (medical, oil/gas) digital mockups, 4k video compositing, and client presentations. Unlike a multi-card GPU solution, the FirePro using Eyefinity has all memory in the same memory block, so almost any CAD or DDC software offers high performance across all of the displays out of the box (See Develop3D story).
Of course the FirePro V9800 offers full DX11, OpenGL 4.X and OpenCL 1.X support, as well as stereo3D.
