Common questions

Can the Apple M1 Ultra run it?

Can the Apple M1 Ultra run Llama 3.3 70B?

Yes. Llama 3.3 70B needs about 45 GB and the Apple M1 Ultra with 64 GB of unified memory leaves about 48 GB for models. Expect about 10 tok/s, about reading speed.

Can the Apple M1 Ultra run gpt-oss 120B?

Yes, with 128 GB or more. gpt-oss 120B needs about 67 GB and the Apple M1 Ultra with 128 GB of unified memory leaves about 96 GB for models. Expect about 97 tok/s, faster than you can read. The 64 GB version doesn't have room.

Can the Apple M1 Ultra run Qwen3 235B-A22B?

No. Qwen3 235B-A22B needs about 144 GB and the Apple M1 Ultra has at most 128 GB of unified memory, of which about 96 GB is usable for models. The most capable model it runs well is gpt-oss 120B, at about 97 tok/s.

How we estimate

Generating a token reads the model's active weights from memory once, so speed is roughly memory bandwidth (800 GB/s) divided by the active weight size, with efficiency calibrated on our own rack. Sizes are Ollama's default 4-bit downloads plus about 1.2 GB for context. macOS lets the GPU use about two thirds to three quarters of unified memory, so that is what we count. Real results are usually within about a third. Measured one yourself? Send us the number.

Want something bigger?

The Ryzen AI Max+ 395 mini PC, 128 GB runs gpt-oss 120B at about 31 tok/s, from $3,400 used.
