AMD Radeon HD 6990 dual-GPU Antilles shown off

AMD's Matt Skynner showed off the dual-GPU Radeon HD 6990 at a recent press event. The card uses two 40nm Cayman GPUs and is equipped with a new cooler design that makes use of a cylindrical blower to draw air from the rear portion of the cooler and circulate it through a vapor-chamber enhanced heatsink. The launch of the Radeon HD 6990 is expected later this quarter.

This time, AMD is toying with a revolutionary new cooler design that makes use of a cylindrical blower (like ones used in air-curtains, on a much smaller scale) to draw air from the rear portion of the cooler, and circulate through the complex vapor-chamber enhanced heatsink inside. In other words, the card lacks a fan intake hole where it's typically located, but the rear portion serves that purpose. Power is drawn in from two 8-pin PCI-E power connectors.
