"AI5 is specially optimized for Tesla use, as it will work alongside the company's Neural Networks to focus on real-time inference to make safe and logical decisions during operation. It was first teased by Tesla in mid-2024 as Musk called it "an amazing design" and "an immense jump" from the current AI4 chip. It will be roughly 4o times faster, have 8 times the raw compute, 9 times the memory capacity, 5 times the memory bandwidth, and 3 times the efficiency per watt."
"Samsung and TSMC will make slightly different versions of the AI5 chip, "simply because they translate designs to physical form differently." However, Musk said the goal is that its AI software would work identically. This was a real concern for some who are familiar with chip manufacturing, as Apple's A9 "Chipgate" saga seemed to be echoing through Tesla. Back in 2015, it was found that Apple's A9 chips had different performances based on who manufactured them."
AI5 is Tesla's next-generation chip for self-driving, Optimus humanoid robots, and other AI-driven vehicle and non-vehicle applications. The chip succeeds AI4 and is optimized for Tesla's neural networks to prioritize real-time inference and safe, logical decision-making. Performance improvements are substantial: roughly 40 times faster, eight times the raw compute, nine times the memory capacity, five times the memory bandwidth, and three times the efficiency per watt. Samsung and TSMC will manufacture slightly different physical versions at their Texas and Arizona fabs, respectively, while Tesla aims for identical AI software behavior across versions. Historical concerns from Apple's A9 "Chipgate" motivate efforts to avoid manufacturing variance.
