MARKHAM, ON - September 21, 2004 - ATI Technologies Inc. (TSX:ATY, NASDAQ:ATYT) today introduced the RADEON(r) X700 family of visual processors. The RADEON X700 delivers excellent graphics performance for gaming and visual processing, at a price suited to a broad range of customers. Delivering a gaming experience that is anything but mainstream, the RADEON X700 visual processing units (VPUs) include the advanced, cutting-edge features previously introduced in ATI's RADEON X800 family of VPUs and a higher level of performance than some of last year's high-end visual processors, but for less than $200.
