Tesla is reportedly working with AMD to develop an advanced autonomous driving chip.

CNBC reports that Tesla recently received back samples of its processor and has started to run tests on it. Although the electric automaker traditionally likes to go about things, including autonomy, on its own, sources suggest that AMD is involved in the project.

Speaking on Wednesday, the chief executive of AMD spin-off and chip fabricator GlobalFoundries, Sanjay Jha, named Tesla as an example of a large company currently working with chip fabricators. In a later statement, the company said it doesn’t comment on customers or potential customers.

Nevertheless, a partnership between Tesla and AMD wouldn’t be surprising. In fact, former AMD chief executive Jim Keller is now Tesla’s head of Autopilot hardware and software. Since Keller landed this position at Tesla, it is reported that a team of over 50 have been working on the initiative under him. Additionally, a number of other AMD veterans have been brought in, including former principal hardware engineer Bill McGee.

Both AMD and Tesla have refused to comment on the reports.
