Larry Hollatz, group vice president of Advanced Micro Devices Inc.'s Computation Products Group, has resigned to pursue other interests, the company confirmed today.
AMD president Hector de J. Ruiz will serve as acting head of the group until a successor for Hollatz is named.
An AMD spokesman declined to discuss the resignation, and Hollatz send word that he would not comment.
The sudden departure raised questions about AMD just at the time that the chip maker is riding a crest of increasing processor sales and besting its archrival Intel Corp. in production of leading-edge processor clock frequencies at 1-GHz and above.
Hollatz, who became head of the computation chip group in 1998, was responsible for the rampup of AMD's Athlon processor. He also headed the Athlon's development when he served as head of the microprocessor group in Austin, Texas. Hollatz joined AMD in 1991 from NCR Corp.
An AMD spokesman said the resignation would have no impact on the company's ramp-up of Athlon production or on the introduction of new higher-performance versions in the next six months.
