BYD has built China’s first 4nm driving chip, and it’s putting LiDAR on a $10,000 car
TL;DR
BYD has unveiled the Xuanji A3, China’s first automotive-grade 4nm chip for self-driving cars, delivering 700 TOPS per chip. The company is expanding its God’s Eye driver-assistance system to mass-market EVs including the $10,300 Seagull, as eight consecutive months of falling sales and a 55% profit decline force a technology-led pivot.
BYD has unveiled the Xuanji A3, which it calls China’s first automotive-grade 4-nanometre chip for self-driving vehicles. CEO Wang Chuanfu announced the chip at an event at BYD’s Shenzhen headquarters on 28 May, saying it delivers the lowest power consumption per unit of compute in its class, drawing roughly 20% less than comparable semiconductors. The chip has already entered mass production.
A single Xuanji A3 delivers 700 TOPS of computing power. A cluster of three chips reaches 2,100 TOPS, enough to support Level 3 and Level 4 autonomous driving functions. The chip is the centrepiece of a new...
