Questions
- What is the best LLM for an M4 Pro with 64 GB?
- Of the models with a published Intelligence Index, Nemotron 3.5 Bolt 74B A9B scores highest among those that run well here: 4-bit, about 24–43 tokens a second.
- Can an M4 Pro with 64 GB run Llama 3.3 70B?
- Yes, but slowly: 4-bit, at about 3–6 tokens a second.
- How fast is gpt-oss-20b on an M4 Pro?
- About 65–115 tokens a second (native 4.25-bit), from the chip’s 273 GB/s memory bandwidth.
Run them with MLX Harness (free, open source) or Apple’s mlx-lm in Terminal: step by step.
How it’s worked out
Memory: the model’s parameters at 8, 6, 4, 3 or 2 bits per weight plus MLX’s group scales (half a bit per weight), or its native format, with room for the context on top. By default macOS lets the GPU use about 75% of unified memory. Speed: memory bandwidth divided by the bytes read per token is the ceiling for one conversation; in llama.cpp’s public Apple Silicon benchmarks real runs reach about 45% to 80% of it, which is the range shown. These are estimates, not measurements: measure your own Mac on MLX Bench. Model figures from each official model card, chip figures from Apple’s Tech Specs. Checked 2026-10-19.
