24 March 2011
Excerpt: Put on the kettle, make yourself comfortable, because you're about to find out which is the fastest graphics card in the world, dear reader. NVIDIA and AMD know all too well that the path to performance domination of the consumer PC graphics market can only be trod if two high-end GPUs are placed onto one board and set to communicate with one another via established multi-GPU technology.
Excerpt: AMD's current flagship graphics card, the Radeon HD 6990, consists of two slightly underclocked 6870 graphics chips on one card. Nvidia's answer is the GeForce GTX 590, which similarly has a pair of underclocked processors in it – two GTX 580 chips running at 607 rather than 772MHz. Nvidia's latest cards are based around clusters of shader processors that Nvidia calls streaming multiprocessors.
