MARKHAM, CANADA – May 23, 2006 – ATI Technologies Inc. (TSX:ATY, NASDAQ:ATYT) is bringing its technology leadership to a new generation of AMD PC users with the introduction of the CrossFireT Xpress 3200 chipset and the ATI RadeonR Xpress 1100 series of chipsets, all compatible with socket AM2. The CrossFire Xpress 3200 is the top-performing enthusiast chipset available today and the Radeon Xpress 1100 prepares users for Windows VistaT with ATI’s fastest integrated graphics ever.

The feature-rich platforms employ ATI’s new southbridge technology, the SB600 series. The SB600 series provides the most connectivity options available today, including 10 USB 2.0 ports, 4 SATA Generation II ports, RAID support, high-definition audio, and support for established connectivity options, such as parallel ATA. The SB600 also makes use of disk controller technologies such as the Advanced Host Controller Interface (AHCI) with native command queuing (NCQ) to provide super-fast access to data storage, making games, applications, and files load faster. In Windows Vista, the new controller also ensures blazing disk performance on AMD systems using the native AHCI driver – something that’s only supported today on ATI platforms.
