BYD unveils 4nm automotive chip for autonomous driving

Chinese electric vehicle giant BYD has unveiled what it calls China's first automotive-grade 4-nanometer chip for intelligent driving, marking a significant push to advance its autonomous technology amid intense market competition. The announcement was made by CEO Wang Chuanfu at a company event in Shenzhen.

The new chip, named Xuanji A3, is now in mass production and is designed to support Level 3 and Level 4 autonomous driving capabilities. A single chip delivers 700 trillion operations per second (TOPS) of computing power, and a cluster of three chips can provide over 2,100 TOPS. Company executives highlighted the chip's energy efficiency, stating it consumes roughly 20% less power than comparable semiconductors. The Xuanji A3 serves as the centerpiece of a new, unified computing platform that integrates a vehicle's smart cockpit, driver-assistance system, and electric propulsion software into a single controller.

Concurrently, BYD announced it will expand its advanced driver-assistance system, marketed as Gods Eye, across all its models sold in China. This includes mass-market vehicles like the Seagull hatchback. LiDAR sensors, technology typically reserved for premium cars,...
