As expected AMD today released the dual-GPU Radeon HD 3870 X2 graphics card. This card features two 55nm Radeon HD 3870 GPUs on a single board and is available in retail stores for $449.
The ATI Radeon HD 3870 X2 is the first enthusiast graphics processors to use TSMC’s 55nm process technology. The smooth transition to 55nm has allowed for a 2X increase in performance-per-watt over the previous generation. Through an elegant board design, the ATI Radeon 3870 X2 delivers exceptional acoustics that are roughly equivalent to a single ATI Radeon HD 3870. When combined with ATI PowerPlay technology, the ATI Radeon 3870 X2 delivers exceptional idle power efficiency with the ability to dynamically raise or lower GPU power depending on the usage scenario.
AMD also said that CrossFire X drivers have been delayed to late Q1 2008.
