AMD on Wednesday bragged of the graphics performance crown with the launch of the ATI Radeon HD 5970. The card uses two 5800 series chipsets on one card to provide the most performance possible. While each has the speed of a 5850 with a 725MHz primary clock speed and 1GHz GDDR5 memory, the 3,200 stream (effects) processors, 160 texture units and 2GB of memory give it as much performance as two 5850s but in half the space.
