Waymo built its own robotaxi chip and published its supplier list
Waymo has published what is in the boot of its robotaxis. A blog post on Thursday set out the architecture of its onboard computer, introduced a custom 5-nanometer chip of its own design, and named the seven suppliers it builds the system with.
The company calls it the first look under its trunk. For a firm that discloses very little about its hardware, it is a substantial opening.
What the chip actually does
This is where the coverage and the company diverge, so it is worth being precise.
The part is an application-specific integrated circuit built on a 5nm process. Waymo describes it as handling “the massive influx of raw data before it reaches our core ML brain”. It extracts information from raw lidar, radar and camera streams, including temporal denoising for better perception in low light, then feeds that into a separate inference engine that runs the sensor-fusion models.
