Tesla P40 vs Arc Pro B60 for local AI

Q: Which is better for local AI, the Tesla P40 or the Arc Pro B60?

The Arc Pro B60, for speed. They fit the same models. Both fit the same models we track, up to Qwen3 32B. The Arc Pro B60 generates about 32% faster on any model both can run, because it has 456 GB/s of memory bandwidth to the Tesla P40's 346 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 Arc Pro B60, 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.
