Tesla starts using in-house developed self-driving AI chip

Tesla announced it has been shipping cars equipped with self-driving technology powered by in-house designed chips. Eventually, the system should enable level 4 or 5 self-driving, which means the driver’s attention is only required under special circumstances or even not at all. Getting there will take time and many firmware updates, however.

Most of the IP used in the 6-billion transistor, 14nm ICs fabbed by Samsung is licensed, but Tesla designed the neural network accelerator block all by itself. CEO Elon Musk called it the “best chip in the world … by a huge margin”. He also claimed it would result in extremely safe self-driving cars and robot taxis.

Tesla says the new self-driving system built around two of the AI chips provides a 21x performance gain at 80 percent of the cost compared to the NVidia-based hardware it was using before. NVidia, however, claims the comparison is unfair.
