It's no secret that Tesla always wanted to develop an in-house chip to handle its cars' autonomous functions. Well, according to CNBC, the EV-maker is close to reaching that goal -- with help from AMD. The company is reportedly building its chip on top of AMD technology and is even working with AMD spin-off and chip fabricator GlobalFoundries to make its vision a reality. It also hired Jim Keller, who previously worked with AMD and Apple, to lead its chip division. In fact, they're far enough in the development process to be able to make samples of the processor's first implementation, and Tesla has already begun testing them.
