Horizon Robotics Unveils First Cabin-and-Driving Integrated Chip

[Technical Breakthrough] Horizon Robotics has launched China's first integrated vehicle intelligence chip for cabin and driving domains, named 'Starry,' scheduled for mass production in 2026.

Core Development: Breaking the Boundary Between Intelligent Driving and Cabin Domains

Horizon Starry 6P adopts a 5nm automotive-grade process, integrating a 20-core CPU and 650 TOPS BPU computing power, with memory bandwidth reaching 273 GB/s. This chip marks the first time that four domains—intelligent driving, cabin, instrument cluster, and vehicle control—are consolidated onto a unified computing platform, challenging the industry’s long-standing "dual-chip separated" architecture.

Strategic Foundation: Cost Pressures Driving Architectural Integration

Amid doubled prices of high-bandwidth memory, automakers have become increasingly sensitive to total intelligent system costs. "One fewer chip, one fewer system" has emerged as a new cost-reduction pathway. Horizon CEO Yu Kai emphasized: "Integration is an unchanging law of computing systems."

Industry Impact: Vehicle Intelligence Operating System Launches in Tandem

The chip will simultaneously support Horizon’s HSD intelligent driving solution and its new vehicle intelligence operating system, accelerating the adoption of central computing architectures in vehicles.
