Powerful visual processors featuring desktop class 3D acceleration

and industry-leading power management available in the award-winning

Apple designs

ATI's (NASDAQ:ATYT) (TSE:ATY) award-winning, industrial-strength mobile visual processor, the MOBILITY(TM) RADEON(TM) 9000 with up to 64MB of integrated DDR RAM is now available in Apple's elegant and powerful Titanium PowerBook G4 notebook, and the powerful MOBILITY(TM) RADEON(TM) 7500 with up to 32MB DDR RAM is now available in the world's most popular consumer and education portable, the Apple iBook.

"The MOBILITY RADEON 9000's version 1.4 pixel shaders bring exciting new special effects to Apple's mobile users, while the MOBILITY RADEON 7500 accelerates 3D visual effects and enables crisp full frame-rate DVD video to deliver a truly immersive multimedia experience to consumers" said Reuven Soraya, Director of Marketing, Mobile Business Unit, ATI Technologies Inc. "ATI is delighted to be working closely with Apple to deliver impeccable 3D graphics and an outstanding overall visual experience to Apple's PowerBook G4 and iBook customers."

"The Titanium PowerBook G4 and the new iBook deliver cutting-edge features in stunning, thin and light portable designs," said Greg Joswiak, vice president of Hardware Product Marketing. "By choosing the world's fastest, most feature-rich mobile graphics processors for both the PowerBook and iBook, we're delivering best-in-class graphics performance to our professional and consumer portable customers."

The MOBILITY RADEON 9000 is the world's most powerful mobile visual processor, and is the first and only mobile visual processor to support version 1.4 pixel and vertex shaders, which deliver breathtaking realism to the latest 3D games. The MOBILITY RADEON 7500 graphics processor brings all the features and performance of a desktop PC to the notebook space, including lightning-fast 3D acceleration, superior video editing capability, smooth DVD (digital versatile disc) playback, integrated TV-out, multi-monitor support, and the ability to run the industry's most graphics-intensive applications.

All of the new Titanium PowerBook G4 and iBook models take advantage of Quartz(TM) Extreme in Mac OS X Jaguar. Quartz Extreme uses the OpenGL-based graphics engine rather than the G4 processor to accelerate the compositing and rendering of 2D, 3D, and QuickTime content. The entire desktop becomes a fully accelerated OpenGL scene to dramatically improve overall system performance and make the graphical user interface more responsive. For all-day mobile use, the new notebooks also offer industry-leading battery life.
