Intel said Wednesday that VMware CEO Pat Gelsinger will return to the chipmaker as CEO, with current chief Bob Swan stepping down as of Feb. 15.

Why it matters: Intel faces a host of challenges from manufacturing issues to competition from rival AMD to Apple's move to use homegrown chips in the Mac.

Between the lines: Intel's woes have spurred calls for a leadership shake-up including from activist investor Third Point.

The other side: The company said in its press release announcing the CEO shift that it expects to exceed its earnings and revenue guidance for the fourth quarter when it reports earnings on Jan. 21.

• The release also said the company "has made strong progress" on its next generation 7-nanometer manufacturing technology and will give a further update when it reports earnings.

Background: Gelsinger worked at Intel for three decades starting at age 18, rising to the upper executive ranks before leaving.

What they're saying: "My experience at Intel has shaped my entire career, and I am forever grateful to this company," Gelsinger said in a memo to Intel workers.

• "To come back “home” to Intel in the role of CEO during what is such a critical time for innovation, as we see the digitization of everything accelerating, will be the greatest honor of my career."

Meanwhile: VMware said CFO Zane Rowe will serve as interim CEO while the company searches for Gelsinger's replacement. Gelsigner will remain on VMware's board of directors.
