AMD World's Fastest Graphics Card HD 6990 AMD HD 6990 Specs | Full Details and Reviews

Video game console developers have the luxury of limiting their avenues of competition to peripherals and first-party/exclusive releases, at least until a new generation of hardware is released. Graphics card manufacturers aren’t quite so lucky, caught as they are in a constant race to one-up competitors with products that offer more visual bang than what’s on the market.
AMD takes the lead today with the release of its Radeon HD 6990 graphics card, the world’s fastest… until the next “world’s fastest” is released, that is. The beastly new video adapter offers plenty more of that visual bang, though it comes at a considerable cost: $699. Yes, you could buy one of the market’s top-shelf tablets for around the same price. That tablet won’t run Grand Theft Auto IV with its settings juiced to the max though, will it?
The HD 6990 is a dual-chip card, featuring two powerful GPUs crammed together onto a single circuit board along with 4GB of GDDR5 memory. It has massive power needs as you might expect, and some reviews call it out for being noisy — this is true of many high-end graphics card, which require constant cooling to prevent overheating — but the card itself is quite powerful, with a built-in switch that boosts the clock speed up from 830MHz to 880MHz.
