(Bloomberg) -- Intel Corp. said top chip designer Jim Keller has resigned for personal reasons, dealing a blow to the world’s biggest semiconductor maker as it tries to reassert its industry leadership.
Keller’s resignation is effective immediately but he will act as a consultant for the company for six months, Intel said Thursday in a statement.
Keller was a senior vice president and general manager of silicon engineering. The former executive at Apple Inc., Tesla Inc. and Advanced Micro Devices Inc. is credited with leading programs that have produced some of the most important components in the industry’s history.
While Intel continues to report record sales, its rivals claim their products are now equal or better in performance and that Intel’s manufacturing delays make it more vulnerable to competition than it has been in years. At the same time, customers such as Amazon.com Inc. are increasingly designing their own processors.
Intel said its technology group, led by Murthy Renduchintala, the company’s chief engineering officer, promoted four engineers to more senior roles.
Keller was a senior executive at PA Semi, which was later acquired by Apple to boost its in-house component efforts. Keller designed some of Apple’s earliest in-house iPhone and iPad chips, which are the main custom components in its best-selling devices.
