BYD unveils Xuanji A3, China's first in-house 4nm smart-driving chip

At its May 28 intelligence strategy event BYD launched the Xuanji A3, an automotive-grade 4nm smart-driving SoC the company calls China's first, with a three-chip cluster delivering more than 2,100 TOPS to support L3 and L4 autonomous driving. Paired with BYD's next-generation God's Eye ADAS stack, the chip is already in mass production and gives the world's largest EV maker full-stack control of its assisted-driving hardware and software just as L3 features begin pushing into mainstream models.
