AMD launches Radeon HD 6990 'world's fastest'

If you are scoring at home, NVIDIA currently has the lead in single-GPU graphics cards with GeForce GTX 580, but ATI's dual-chip Radeon HD 5970 is the absolute speed crown for a good long time to maintain. Now, with the name of AMD's Radeon HD 6990, steals the heir apparent and demands attention as the fastest single expansion card, you can hook up your shiny new motherboard. The 6990 has a massive 4GB GDDR5, 3072 stream processors, 64 ROPS, and a 830MHz core clock. A dual-BIOS switch, you can crank the clock to 880MHz with a corresponding increase inof the voltage ,but do not expect too much space above overclocking to see .

Critics note, in addition to their fawning review of the world's best performance, the HD 6990 a massive power-hungry card (375W TDP) and that a lot of noise, while Hercules through their tasks. This is despite a new steam room cooling system that supposedly supports up to 450W heat output. If all this suggests a somewhat weak performance, maybe you will join us NVIDIA will offer answers soon, as the GTX 590 in a position to present a clean, efficient attack on the peaks of the extreme graphics performance.
