AMD Radeon HD 5870 X2 Pictured
Behold AMD's, and soon aimed to be the industry's most powerful graphics accelerator: Radeon HD 5870 X2 "Hemlock". Armed with two "Cypress" Radeon HD 5870 graphics processors, this dual-GPU monstrosity packs twice the shader compute power. From the looks of it, the card is slightly longer than its single-GPU sibling from the series, and is better ventilated, although the cooler design more or less resembles it. It draws its power from one 6+2 pin and one 6 pin PCI-E power connectors, just like two of its ancestors in the R700 and R680. Listed for pre-order on a European online store, a Radeon HD 5870 X2 by Club3D is priced at 677 EUR (incl. applicable taxes, 568.9 EUR excluding).
