ATI and its board partners continue to be the only source
for DirectX® 9 graphics solutions

MARKHAM, ON, March 3, 2003 - ATI Technologies Inc. (NASDAQ: ATYT; TSX: ATY) today reached a remarkable milestone, shipping its one millionth DirectX® 9 compliant cinematic visual processing unit (VPU). One million users are now able to experience cinematic-quality graphics and blistering performance with RADEON(tm) 9700- and RADEON(tm) 9500-based products powered by the world's fastest and most advanced VPUs. ATI and its board partners continue to be the only source for DirectX® 9 graphics products.

Most, if not all, DirectX® 9-class games currently on the market or in development have used ATI products as the development platform. ATI has seeded the game development community with thousands of RADEON 9700 and RADEON 9500 products. With stable hardware and software, the products have provided an excellent platform for development of DirectX® 9 games in many game studios. Game developers are also excited about the install-base this has provided, creating a strong market for DirectX® 9 games.

"We congratulate ATI on shipping one million units. We're pleased to see that all of ATI's DirectX® 9 graphics products, from the RADEON 9500 to the RADEON 9700 PRO, provide the same advanced feature-set," said Mark Rein, Vice President, Epic Games Inc.

ATI's DirectX® 9 rollout was well timed and executed, delivering high-end, mainstream and multimedia products based on the RADEON 9700 and 9500 chips beginning in August 2002, hitting key OEM and retail inflection points. ATI delivered CATALYST(tm), a suite of software including a unified DirectX® 9 driver for its entire range of RADEON products concurrent with Microsoft's release of DirectX® 9 in November 2002.

"ATI promised and delivered when it came to our RADEON 9700 and RADEON 9500 products. The performance, features, stability and availability all met or exceeded the expectations of the market," said Rick Bergman, Senior Vice President of Marketing and General Manager, Desktop, ATI Technologies Inc. "I'm confident that ATI will continue to lead the market with DirectX® 9 solutions. As we have said already, we are on the brink of expanding our offering of DirectX® 9-class products at a variety of price points to satisfy the market, broadening our install base of DirectX® 9 products from one million to millions."
