Hollatz, whose official title was group vice president of AMD's computation products unit, will be replaced on an interim basis by AMD's president, Hector Ruiz. Hollatz oversaw processor design operations in Texas and California, as well as the sales effort for AMD's PC chips.
"I look forward to working directly with the leaders of the computation products group," Ruiz said in a statement. "PC processors represent our greatest growth opportunity."
AMD would not say what Hollatz will do next, only stating that he is leaving to pursue other interests. Hollatz declined to comment on the matter.
Ruiz joined AMD from Motorola earlier this year, becoming the No. 2 man behind chief executive Jerry Sanders. Ruiz is the likely successor to Sanders, whose contract expires next year at the Sunnyvale, Calif.-based company.
Hollatz had been with AMD since 1991, when he was named vice president of the company's embedded products division. In 1995, he became head of the PC products division and also headed the company's Texas microprocessor unit before assuming his current role. Before joining AMD, Hollatz spent nine years at NCR's microelectronics division.
The departure comes as AMD appears to be on a roll. AMD told CNET News.com earlier this week that the company is on track with plans to ship 3.6 million Athlon and Duron processors this quarter, double the number shipped in the second quarter. It also said it expects to ship 7.2 million of its advanced processors in the fourth quarter.
Meanwhile, rival Intel has stumbled. The chipmaker has struggled to keep up with rising demand and has had trouble delivering its speediest processors in volume. On Monday, Intel recalled its fastest chip, the 1.13 GHz Pentium III, because of a glitch in the circuitry.
