[News] Tesla AI5 Reportedly Uses SK hynix Memory, Samsung LPDDR5X; Samsung SF2T Process Applied Ahead of AI6
What happened
Tesla's AI5 chip prototype was manufactured at Samsung's Korean foundry, marking a potential shift from its historical reliance on TSMC. Samsung is applying a custom SF2T process for Tesla, reportedly offering a 30% unit cost advantage over TSMC, though its 2nm yields remain below profitable levels. 利多: Potential long-term supply diversification for Tesla; 利空: Samsung's yield challenges pose execution risk; 关注: Future allocation split between TSMC (AI6.5) and Samsung (AI6).
