RADEON® X800 XL and RADEON® X850 XT now available for AGP customers

MARKHAM, ON/ Munich, Germany - February 28, 2005 - ATI Technologies Inc. (TSX: ATY, NASDAQ: ATYT) today enhanced its family of graphics products for gamers and enthusiast PC users by announcing and shipping AGP versions of its popular RADEON® X800 XL graphics cards and RADEON® X850 XT graphics processors.

The RADEON X800, X800 XL and X850 Series visual processors originally debuted in December for PCI Express based systems. PCI Express is rapidly replacing AGP in new PC's as the primary interconnect technology between the main processor and the graphics subsystem. These new AGP variants will allow users who have not yet upgraded to PCI Express to experience the same great performance and image quality.

"The RADEON X800 XL and RADEON X850 products are perfect for gamers looking to upgrade their AGP systems to play the latest games," said Peter Edinger, Vice President and Managing Director, ATI Technologies (Europe) GmbH. "ATI will continue to deliver leading-edge graphics solutions like these for AGP as well as PCI Express to support the large install base."

The RADEON X850 is a native AGP visual processor family featuring the RADEON X850 XT and other models. The RADEON X800 XL uses ATI's PCI Express to AGP Bridge chip, which allows PCI Express graphics processors to be used in AGP-based computers. RADEON X800 XL and RADEON X850 AGP products from ATI and ATI board partners are available through a variety of retail and e-tail outlets as well as through OEMs and system builders.
