Ryzen AI Max 390 (Radeon 8050S) vs Jetson AGX Orin for local AI

Both fit the same models we track, up to Llama 3.3 70B. The Ryzen AI Max 390 (Radeon 8050S) generates about 25% faster on any model both can run, because it has 256 GB/s of memory bandwidth to the Jetson AGX Orin's 205 GB/s.

The numbers that matter

Memory and bandwidth

Memory decides which models fit. Bandwidth decides how fast they generate, because every token reads the model's active weights once.

Which should you get?

The Ryzen AI Max 390 (Radeon 8050S), for speed. They fit the same models. Price matters as much as either number: check used prices on the builds page, where every parts list has a measured or estimated speed.

How we estimate

Both columns use the same formula: memory bandwidth divided by the weights read per token, calibrated on our own rack, with Ollama's default 4-bit sizes. Real results are usually within about a third. Measured either one? Send us the number.
