AMD claims 'fastest graphics card in the world'
Two Cayman GPUs, no waiting
AMD has unveiled a dual-GPU, easily overclockable, 3D-capable, DirectX 11–supporting consumer graphics card that it claims is "the fastest graphics card in the world".
Spec-wise, the 6990 is impressive. A few of the gnarly bits: a stock engine clock running at 830MHz, overclockable to 880MHz; a memory clock of 1.25GHz; 4GB of GDDR5 memory, addressable at 5Gbps; a max of 320GBps of memory bandwidth; and a raft of processing muscle in its TeraScale 3 architecture, including – counting both Cayman cores – 3,072 stream processors, 192 texture units, 128 Z/Stencil raster operator units, 64 color raster operator units, and dual geometry and rendering engines.
