A few days earlier, AMD's Matt Skynner displayed the company's newest graphics card that seeks to extend the performance leadership currently held by Radeon HD 5970. The dual-GPU AMD Radeon HD 6990, codenamed "Antilles", makes use of two 40 nm "Cayman" GPU, which powers the single-GPU HD 6950 and HD 6970. The core configuration of Cayman in Antilles is not known. The card itself keeps up with the product styling that all Radeon HD 6000 series carry, it's about as long as the HD 5970.
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. AMD is expected to release the new enthusiast graphics card in this quarter.
