"TSMC is the other. TSMC is using its 3nm process, reportedly, while Samsung will do a 2nm as a litmus test for the process. The different versions are due to the fact that 'they translate designs to physical form differently,' CEO Elon Musk said recently. The goal is for the two to operate identically, obviously, which is a challenge. Some might remember Apple's A9 'Chipgate' saga, which found that the chips differed in performance because of different manufacturers."
"The AI5 chip is Tesla's next-generation hardware chip for its self-driving program, but it will also contribute to the Optimus program and other AI-driven features in both vehicles and other projects. Currently, Tesla utilizes AI4, formerly known as HW4 or Hardware 4, in its vehicles. Tesla teases new AI5 chip that will revolutionize self-driving AI5 is specialized for use by Tesla as it will work in conjunction with the company's Neural Networks, focusing on real-time inference to make safe and log"
Samsung is accelerating preparation for U.S. production of Tesla's AI5 chips by hiring veteran engineers for its Customer Engineering team to resolve complex foundry challenges, stabilize production and yields, and ensure smooth manufacturing. The hiring push signals rapid progress on Tesla's AI5 project and underscores Samsung as one of two suppliers chosen by Tesla. TSMC is the other supplier, reportedly using a 3nm process while Samsung will test 2nm. Differences in how designs translate to physical form create a challenge for identical operation. AI5 will power self-driving, Optimus, and other real-time AI features, with availability expected in late 2026 or early 2027.
