Facebook started dropping hints that it has huge processor ambitions a few months ago when it put up job listings to fill positions for a new team. One of the listings called for a person to manage an "end-to-end SoC/ASIC, firmware and driver development organization." While Facebook is one of the biggest companies in the world, it's not exactly known for hardware like Apple and other tech giants are. Hiring an industry veteran who headed Google's chip team could help it achieve its goals and prevent the project from becoming a waste of time and resources.
The company has refused to talk about Rabii and the new team with Bloomberg, so it has yet to reveal if it's using home-grown chips with the devices it's reportedly working on. According to previous reports, Facebook is developing a tablet for video calls and an Echo-/Home-like smart speaker. The publication says Rabii will report to Andrew Bosworth, the company's head of virtual reality and augmented reality. Whether that means Facebook is making its own chips for Oculus devices, however, remains to be seen.
