Overview
- Tesla said its AI5 chip taped out Wednesday, the final design handoff to chip fabs before fabrication, and TSLA rose about 0.66% in premarket trading.
- Elon Musk says AI5 delivers about 8× the compute, 9× the memory, and 5× the bandwidth of AI4, with single‑chip inference comparable to Nvidia’s H100 for Tesla’s workloads, claims that await independent tests.
- Production plans call for dual U.S. sourcing at TSMC’s Arizona fab and Samsung’s Texas plant, alongside an in‑house Terafab now being built in Austin.
- Tesla targets first silicon samples in late 2026 and high‑volume output by mid‑2027, so the Cybercab robotaxi will launch on existing AI4 hardware.
- AI5 is a custom system‑on‑chip for real‑time inference in Tesla cars and the Optimus robot, designed to run much larger on‑device neural networks at lower power and cost.
