Rivian unveils its own in-house RAP1 AI chip and ACM3 self-driving platform—automaker one-ups Tesla with LiDAR support

Rivian has introduced its custom-made RAP1 AI chip and ACM3 self-driving platform, surpassing Tesla by incorporating LiDAR support. The RAP1 chip features 14 Cortex-A720AE cores and is built on a 5 nm process, designed to enhance computing power with RivLink. The ACM3 system boasts 1,800 TOPS of INT8 inference for self-driving tasks, including processing 5 billion pixels per second from camera feeds. Rivian plans to implement LiDAR in its R2 vehicle by late 2026 and offers an Autonomy+ service for safety enhancements, distancing itself from claiming full self-driving capabilities. The company's focus on software and services, alongside its joint venture with VW Group for EV technology, indicates a strategic shift towards profitable ventures beyond traditional automotive manufacturing.
