Edge AI Accelerators — Coral, Jetson, Movidius
Rather than comparing whole SBCs like the Raspberry Pi or Jetson, this piece narrows in on the "AI inference accelerator" chips that sit on top of them, comparing three design philosophies — Google Coral (Edge TPU), Intel Movidius (Myriad X), and NVIDIA Jetson Orin NX. It traces the principle behind why INT8 quantization trades accuracy for speed, through a real example of a Skydio drone running nine neural networks concurrently on a single Jetson TX2, to the state of Coral, effectively abandoned by Google but kept alive by its community.
