Rivian Stock Soars 13% After Unveiling Its Own in-House RAP1 AI Chip

Rivian stock soared 13% on Friday. Rivian announced its Rivian Autonomy Processor chip and Autonomy Compute Module 3 platform, ready for integration in its own vehicles, and likely those of other automakers.

The Rivian Autonomy Processor (RAP1) is a bespoke in-house effort. The chip itself is an Armv9 design, with 14 Cortex-A720AE cores. and is manufactured on a 5 nm process. It has support for the company's own RivLink (no relation or comparison with Nvidia's NVLink), an interconnect that Rivian says provides extensibility to computing power by adding other chips, presumably similar, but there aren't many details.

The RAP1 is the cornerstone of the Autonomy Compute Module 3 (ACM3), a vehicle computer system focused on self-driving capabilities. Its claimed abilities include 1,800 TOPS of INT8 inference, enough grunt to process 5 billion pixels per second of camera feeds.
