AMD AND ATI ANNOUNCE MERGER CONTROL CLEARANCES IN
CONNECTION WITH PROPOSED ACQUISITION

SUNNYVALE, CALIF. and MARKHAM, ONTARIO — Sept. 6, 2006 — Advanced Micro Devices, Inc. (NYSE: AMD) and ATI Technologies Inc. (TSX: ATY, NASDAQ: ATYT) today announced that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, relating to the proposed acquisition of ATI by AMD, has expired. In addition, the Commissioner of Competition issued an advance ruling certificate in connection with the proposed acquisition under the Canadian Competition Act, and the German Federal Cartel Office likewise has cleared the transaction. As a result, the conditions to the acquisition relating to U.S., Canadian and German antitrust approvals are now satisfied.

The proposed acquisition was announced on July 24, 2006 and remains subject to the approval of ATI shareholders, court approval of the plan of arrangement, and certain other regulatory approvals, including approval by the Minister of Industry under the Investment Canada Act and prior clearance under competition laws in Taiwan, as well as other customary closing conditions. The transaction is expected to be completed during ATI’s first quarter of fiscal 2007, which ends November 30, 2006.

A special meeting of ATI shareholders to approve the transaction is scheduled to be held on October 13, 2006 in Toronto. A court hearing to confirm, among other things, the mechanics of the mailing of the Notice of Special Meeting and Management Information Circular, and the meeting date, has been scheduled for September 13, 2006.

“We are pleased to pass through the HSR waiting period and receive clearance from the Canadian Competition Bureau and the German Federal Cartel Office,” said AMD Chairman and CEO Hector Ruiz. “We look forward to the October 13th ATI shareholder vote and additional regulatory approvals, and to merging the companies to drive growth, innovation and choice for our customers, partners and the industry.”

“Our integration planning is underway and the more closely we get to know the team at AMD, the more excited we are about the opportunities and potential for the combined organization and our customers once the deal is completed,” said David Orton, President and Chief Executive Officer of ATI.

ATI Announces Preliminary Revenue Estimate for Fourth Quarter

MARKHAM, Ontario – September 6, 2006 – ATI Technologies Inc. (TSX: ATY, NASDAQ: ATYT) today announced that consolidated revenue for the fourth quarter of fiscal 2006 is currently expected to be approximately $520 million(1). This is below the low end of the revenue range provided on June 29, 2006, before the announcement of the acquisition agreement with Advanced Micro Devices, Inc. (NYSE: AMD).

The anticipated revenue shortfall is due primarily to lower sales volumes of integrated chipsets for Intel-based platforms. In addition, handheld revenue was lower than expected, reflecting a supply chain adjustment by one of ATI’s major customers. We believe this adjustment is temporary in nature and should not have a long-term impact on revenue.

“While we anticipated a decline in future Intel-based chipset business following the announcement of the acquisition agreement with AMD, the decrease occurred much sooner than we expected,” said Dave Orton, CEO of ATI Technologies Inc.  “Our other product lines are quite healthy and the response to our recent handheld, digital TV and GPU product announcements has been extremely positive from both customers and from the overall market.”

Important Information Regarding Forward-looking Statements

Forward-looking statements look into the future and provide an opinion as to the effect of certain events and trends on the business, and may include words such as “plans,” “intends,” “anticipates,” “should,” “estimates,” “expects,” “believes,” “indicates,” “targeting,” “suggests” and similar expressions. These “forward-looking” statements are based on current expectations and entail various risks and uncertainties.

This news release contains forward-looking statements about ATI’s objectives, strategies, financial condition and results. Our actual results may materially differ from our expectations if known and unknown risks or uncertainties affect our business, or if our estimates or assumptions prove inaccurate. Therefore we cannot provide any assurance that forward-looking statements will materialize. We assume no obligation to update or revise any forward-looking statement, whether as a result of new information, future events or any other reason. Additional information concerning risks and uncertainties affecting our business and other factors that could cause our financial results to fluctuate is contained in our filings with Canadian and U.S. securities regulatory authorities, including our 2005 Annual Information Form and 2005 Annual Report filed on SEDAR at http://www.sedar.com.
