About the Mac Studio M2 Max (64 GB)

The Mac Studio M2 Max is a 64 GB desktop with more memory than speed: it runs 27–35B models well and fits 120B MoE. macOS keeps about 3.5 GB, leaving 60.5 GB for models. Prompt reading is its weak spot: a 4K-token prompt waits 53 s before the first word on Qwen3.8 27B. M2 Max generation, released 2023; the newer M3 Max writes 1% faster with 1.3× the compute.

Mac Studio M2 Max strengths and weaknesses

Strengths

  • Runs 120B MoE models: GPT OSS 120B at 57.0 tok/s in 59.1 GB
  • Room for long context: Qwen3.8 27B at Q4 uses 17.9 GB, leaving 42.6 GB free

Weaknesses

  • Slow on large dense models: Llama 3.3 70B Instruct at 6.0 tok/s
  • Slow prompt reading: A 32K-token prompt on Qwen3.8 27B waits 7.1 min for the first token
  • No CUDA: vLLM, AWQ, GPTQ and FP8 builds don't run; use GGUF or MLX

What is the largest model the Mac Studio M2 Max (64 GB) can run?

GPT OSS 120B (116.8B) at Q4_0 uses 59.1 GB, 98% of the available memory, and runs at about 57.0 tok/s.

Can the Mac Studio M2 Max (64 GB) run Qwen3.8 27B?

Yes. Qwen3.8 27B fits at Q4_K_M, using 17.9 GB of the 60.5 GB available, and it is the best model that runs well on this machine.

Can the Mac Studio M2 Max (64 GB) run 70B models?

Yes, but slowly: Llama 3.3 70B Instruct at Q4_K_M uses 51.3 GB and writes about 6.0 tok/s.

How long does the Mac Studio M2 Max (64 GB) take to read a long prompt?

On Qwen3.8 27B, about 53 s for a 4K-token prompt and 7.1 min for a 32K-token document before the first word appears.

Is renting a GPU cheaper than buying the Mac Studio M2 Max?

An A100 (80 GB) rents from $1.07/hr.
