BYD Unveils Self-Developed 4nm Intelligent Driving Chip

[Technical Breakthrough] BYD has launched China's first self-developed 4nm automotive-grade intelligent driving chip, 'Xuanji A3,' and pledged full financial liability coverage for urban navigation safety incidents.

Core Development: Xuanji A3 Achieves Mass Production, Filling Domestic Gap in High-End Intelligent Driving Chips

The Xuanji A3 adopts a 4nm automotive-grade process, delivering over 700 TOPS of computing power per chip and 2100 TOPS when three chips are combined. It supports L3/L4 autonomous driving and has already entered mass production.

Key Specifications: Leading Performance and Energy Efficiency

The chip integrates a 16-core CPU, offers 273 GB/s memory bandwidth, achieves ASIL-D functional safety certification, consumes 20% less power per unit of computing performance compared to peers, and doubles (100% increase) computing utilization efficiency.

Strategic Foundation: Full-Stack In-House Development + Safety Guarantee Accelerates Mass Adoption of Intelligent Driving

BYD has upgraded its 'God’s Eye 5.0' system and committed that if a user experiences a liable accident while properly using the urban navigation feature within one year, BYD will directly compensate for all economic losses, promoting widespread accessibility of advanced intelligent driving.
