Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

Item 1.01 Material Definitive Agreement

On April 28, 2005, Advanced Micro Devices, Inc., or the Company, accelerated the vesting of all stock options outstanding under the Company’s 2004 Equity Incentive Plan and the Company’s prior equity compensation plans that have exercise prices per share higher than the closing price of the Company’s stock on April 27, 2005, which was $14.51. Options to purchase approximately 12 million shares of the Company’s common stock became exercisable immediately. Options held by non-employee directors were not included in the vesting acceleration.

The primary purpose of the accelerated vesting was to eliminate future compensation expense the Company would otherwise recognize in its statement of operations with respect to these accelerated options upon the adoption of Financial Accounting Standards Board Statement of Financial Accounting Standards No. 123 (Revised 2004), Share-Based Payment (“SFAS 123R”). SFAS 123R is effective for the Company beginning in the first quarter of 2006, and will require that compensation expense associated with stock options be recognized in the statement of operations, rather than as a footnote disclosure in the Company’s consolidated financial statements. The acceleration of the vesting of these options did not result in a charge based on generally accepted accounting principles.

Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Officers

On April 28, 2005, the date of the Company’s Annual Meeting of Stockholders, Mr. Charles M. Blalack and Dr. R. Gene Brown retired from the Company’s Board of Directors and did not stand for re-election.
