       QUALCOMM and ATI Join Forces to Create Wireless 3D Gaming Platform

         -- Industry Leaders Unleash the Power of Wireless 3D Gaming --

ATLANTA -- March 22, 2004 -- QUALCOMM Incorporated (Nasdaq: QCOM), pioneer and
world leader of Code Division Multiple Access (CDMA) digital wireless
technology, and ATI Technologies Inc. (TSX: ATY, Nasdaq: ATYT), the global
leader for mobile graphics, today announced a strategic technology collaboration
to create the next-generation wireless 3D gaming platform. As part of the
collaboration, QUALCOMM's industry-leading Mobile Station Modem(TM) (MSM(TM))
baseband solutions will include ATI's highly optimized IMAGEON(TM) architecture
to provide a fully featured, high-performance 3D gaming solution for 3G
CDMA2000(R) and WCDMA (UMTS) devices.

QUALCOMM will license and integrate the IMAGEON technology for its
next-generation MSM7xxx(TM) family of chipsets, and will enable ATI to interface
IMAGEON Application Specific Integrated Circuits (ASICs) to QUALCOMM's
MSM6xxx(TM) chipsets -- providing QUALCOMM's manufacturing partners with a fully
tested 3D multimedia hardware solution.





                                                                         4 of 8


This collaboration creates a rich 3D graphics and development environment which
includes QUALCOMM's BREW(TM) solution, industry standard APIs, ATI's PC-level
performance, and well established developer programs. This enables the
development of value-added games for the mobile environment and easy porting to
mobile devices, of some of the world's most popular PC and console-based games,
resulting in new revenue generating opportunities for wireless operators and
content providers.

"QUALCOMM and ATI have joined forces to deliver a superior 3D graphics solution
to the wireless industry, furthering QUALCOMM's commitment to continually
developing new uses for wireless," said Dr. Sanjay K. Jha, president of QUALCOMM
CDMA Technologies. "Combining our leadership in wireless communications with
ATI's leading graphics expertise establishes a new standard of excellence for
wireless 3D graphics applications and devices."

"ATI is pleased to partner with QUALCOMM as the wireless industry leader to
increase the commercial availability of 3D gaming and multimedia devices and
services for 3G CDMA," said Dave Orton, president and chief operating officer,
ATI Technologies Inc. "We are leveraging many years of expertise in graphics and
3D gaming across all platforms as well as our vast and strong relationships with
content providers to offer an outrageous 3D graphics experience for wireless
consumers in a very low power environment."

"ATI and QUALCOMM, through the BREW solution, will assist Verizon Wireless to
deliver an extreme 3D gaming experience to our customers," said James Straight,
vice president of wireless data and multimedia services for Verizon Wireless.
"The combination of the BREW system and ATI's graphics solution, will enable
publishers and developers to push the envelope with their exciting mobile
offerings, giving our customers a superior gaming experience."







                                                                         5 of 8

This collaboration will leverage the revenue-generating opportunities of the
rapidly growing wireless gaming industry. IDC estimates that wireless gaming
revenue could generate USD $1 billion by 2006 for wireless carriers in the
United States.

QUALCOMM will showcase a variety of 3G CDMA wireless products and solutions at
CTIA Wireless 2004 in Atlanta, March 22-24 in booth number 3931 (hall B4) at the
Georgia World Congress Center. QUALCOMM will hold a press conference on
"Multimedia Convergence" on Monday, March 22 from 2-2:30 p.m. in the CTIA 2004
press conference facilities. ATI executives will be available to provide
additional details on this collaboration.

QUALCOMM's chipsets include access to QUALCOMM's BREW solution. The BREW system
enables the development and monetization of advanced applications and content,
allowing operators and OEMs to differentiate their products and services and
increase revenues. QUALCOMM's chipsets are also compatible with the Java runtime
environment; J2ME(TM) can be built entirely on the chipset as an extension to
the BREW solution.

ATI Technologies Inc. is the world leader in the design and manufacture of
innovative 3D graphics and digital media silicon solutions. An industry pioneer
since 1985, ATI is the world's foremost visual processor unit (VPU) provider.
ATI is dedicated to delivering leading-edge performance solutions for the full
range of PC and Mac desktop and notebook platforms, workstations, set-top and

Americas, Europe and Asia. ATI common shares trade on NASDAQ (ATYT) and the
