According to a Korean website called Asiae, Tesla is talking with Samsung about building an infotainment chip based on Samsung’s 5nm technology.
I did not realize this, but Samsung is already building Tesla’s current, Hardware 3.0 custom chip. That chip is based on Samsung’s 14nm technology.
Apparently the 5nm technology is based on extreme ultravoilet lithography, a technique that only Samsung and TSMC utilize.
I’ve always thought about chip manufacturing as a kind of boring and commodity endeavor, but with all the analysis of Intel vs. Samsung vs. TSMC vs. NVIDIA vs. Hauwei, I should probably start reading more about extreme ultraviolet lithography.
