Can the Jetson AGX Orin run Llama 3.3 70B?
Yes, with 64 GB or more. Llama 3.3 70B needs about 45 GB and the Jetson AGX Orin with 64 GB of unified memory leaves about 48 GB for models. Expect about 3 tok/s, slow, but it works. The 32 GB version doesn't have room.

Speed is roughly memory bandwidth divided by the weights read per token, calibrated on our own rack. Sizes are Ollama's default 4-bit downloads plus about 1.2 GB for context. Real results are usually within about a third. Measured it yourself? Send us the number.
