Tesla's Full Self Driving Chip Detailed
Tesla's new chip features dual neural network arrays that are capable of a huge 36 trillion operations per second, each, which is where the 21x faster than NVIDIA's offerings comes into play.
The GPU on Tesla's new self-driving chip is clocked at 1GHz with 600 GFLOPs of performance.
The main processor packs 12 x ARM A72 64b CPUs clocked at 2.2GHz.
Security is important for a self-driving chip with Tesla's security system ensuring that the system "only runs code cryptographically signed by Tesla".
Better yet, Tesla's new self-driving chip will cost the company just 80% of what it was paying NVIDIA for that massive 21x performance gain, and do it by drawing only a bit more power at 72W, versus NVIDIA's lower 57W.
The company will be pumping out the new Full Self Driving Computer boards with two of the chips, which is used for redundancy. You don't want a full self-driving car relying on a single processor and then that processor fails, so the inclusion of a second processor is a pretty crazy thing for Tesla to offer.
