AMD used CeBIT 2008 as an opportunity to formally announce the release of its ATI Catalyst 8.3 set of drivers for its line of Radeon graphics cards. While this release has long been expected and is no surprise, AMD said the drivers will be available for download beginning March 5. What is significant about this release beyond the usual bug fixes and enhancements is support for CrossfireX and ATI Hybrid Graphics. CrossfireX is ATI's new technology allowing the use of three or four GPUs in a single system. That can translate up to 3.2 times the performance over a single graphics processor under certain scenarios. CrossfireX allows the mixing and matching of ATI's 3850, 3870 or 3870 X2 cards in any combination. ATI Hybrid Graphics allows the use of a single discrete videocard in combination with an onboard graphics processor to achieve up to 70% performance boost without having to purchase a second card. In addition ATI Catalyst 8.3 will offer DirectX 10.1 support for the ATI Radeon HD 3000 series, various anti-aliasing enhancements, HydraVision support for Windows Vista and GPU scaling for widescreen monitors.
