About the Mac Studio M1 Max (64 GB)

The Mac Studio M1 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 73 s before the first word on Qwen3.8 27B. M1 Max generation, released 2022; the newer M2 Max writes 0% faster with 1.4× the compute.

Mac Studio M1 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 9.7 min for the first token
  • No CUDA: vLLM, AWQ, GPTQ and FP8 builds don't run; use GGUF or MLX
