Most folks would think of Rivian as a runner-up to Tesla thanks to its aluminum unibody R1 vehicles, but the automaker has actually been making a tidy sum in software and services. True to that statement, Rivian today 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.
