Rivian's groundbreaking autonomy technology, built on Arm's cutting-edge compute platform, is revolutionizing the physical AI landscape. In a significant development, Rivian unveiled its third-generation in-house autonomy hardware platform, the Rivian Gen 3 Autonomy Computer, during its Autonomy and AI Day. This platform is a testament to the power of collaboration, as it features a custom chip, the Rivian Autonomy Processor (RAP1), developed in close partnership with Arm. The RAP1, built on Arm's state-of-the-art Armv9 architecture, forms the backbone of Rivian's advanced autonomy capabilities. It enables vehicles to interpret their surroundings, predict future scenarios, and make safe, reliable decisions in milliseconds. This level of safety and efficiency is crucial for autonomous machines operating in dynamic environments. By leveraging Arm's compute platform, Rivian can deliver high performance without sacrificing range or efficiency, ensuring a reliable foundation for future vehicle generations and physical AI applications. This partnership exemplifies how deeply integrated AI is transforming the capabilities of vehicles and machines, with intelligence, safety, and efficient compute at the core of physical AI's real-world impact.
