Close development between ATI and software partners provides best of breed solutions for professional users while ensuring stability, compatibility and performance

Markham, Ontario - Monday, May 05, 2003 - Industry leading vendors of over 30 workstation software applications have certified the FireGL(tm) X1 and
FireGL(tm) Z1 workstation graphics accelerator cards from ATI Technologies Inc. (TSX: ATY, NASDAQ: ATYT). The FireGL certification by CAD, DCC, AEC, GIS and visual simulation application vendors assures professional engineers, designers and animators that the FireGL line delivers a stable and high performance workstation graphics environment on both Windows and Linux platforms.

The rigorous and exacting certification processes, conducted by software
vendors, puts ATI's FireGL graphics accelerators up against a battery of
simulations and real-world scenarios, ensuring compatibility and stability required by workstation users. ATI's quality assurance engineers also carry out comprehensive compliance, performance and functionality verification tests, and work closely with application and workstation vendors to refine the FireGL products, thereby creating the highest level of reliability and performance.

"Leading manufacturers around the globe rely on PTC's Pro/ENGINEER* to provide the best solution to fit their product development needs," commented Jon Beaulier, Alliance Manager for PTC. "After extensive testing of the FireGL, we can certify that ATI's latest workstation solutions give our customers the reliability and performance they have come to expect from both PTC and ATI."

"SolidWorks® software users demand that their workstation platform executes flawlessly in their production environments," stated Antony Hervo, Solution Partner Marketing Manager for SolidWorks Corporation. "By certifying ATI's FireGL accelerators, we attest that these innovative graphics cards excel in the day-to-day rigors of complex modeling and production work that our customers perform."

"Professional 3D users expect the most robust and feature-rich solutions from Alias|Wavefront and our hardware partners," said Rob Hoffmann, senior Maya product manager, Alias|Wavefront. "By running ATI's new FireGL through a rigorous and thorough testing process on both Windows and Linux platforms, we ensured that the combination of the FireGL accelerators with Maya and StudioTools gives users an extremely powerful and stable work environment."

"The SOFTIMAGE|XSI, SOFTIMAGE|3D and SOFTIMAGE|BEHAVIOR production environments running on Windows and Linux offer digital content creators a valuable choice when selecting an operation system," said Alan Waxenberg, business manager of third party programs for Softimage. "The certified FireGL for Linux and Windows from ATI gives Softimage users powerful, cross-platform graphics solutions that deliver the features, precision and brute-force power to blaze through even the most challenging projects."
