Jeff Wilcox, head of Mac systems architecture, returns to work at Intel. He is one of the driving forces of Apple Silicon, with Apple leaving Intel as a customer.

The chip designer worked at Apple for eight years and headed the transition to Apple Silicon. In his new role at Intel, he will be responsible for the System-on-a-chip (SOC) designs. Formally, he becomes Intel Fellow as Design Engineering Group CTO, Client SoC Architecture.

Wilcox announced his departure from Apple on LinkedIn a while back, now being supplemented by confirmation that he is moving to Intel, where he previously worked from 1997 to 2007 and from 2010 to 2013. In between, he was also briefly active at Nvidia and Magnum Semiconductor.

During his tenure at Apple, the company switched from Intel chips to its own Apple Silicon-based ARM architecture. As a result, Intel lost one of its largest customers. In the meantime, some changes have been made at Intel.

For example, Pat Gelsinger, who previously worked for the company for thirty years, became CEO, and the company announced some structural and strategic changes to its chip business.
