About the MacBook Pro 14" M5 Max (128 GB)

The MacBook Pro 14" M5 Max is one of the fastest 128 GB machines: it runs 27–31B and 120B MoE models well. Among 128 GB machines, only the M1 Ultra and M2 Ultra write faster. macOS keeps about 3.5 GB, leaving 124.5 GB for models. With 68 TFLOPS it reads long prompts faster than most 128 GB machines: a 4K-token prompt takes 17 s. M5 Max generation, released 2026.

MacBook Pro 14" M5 Max strengths and weaknesses

Strengths

  • Runs 120B MoE models: GPT OSS 120B at 65.5 tok/s in 70.8 GB
  • Room for long context: Qwen3.8 27B at Q4 uses 17.9 GB, leaving 106.6 GB free

Weaknesses

  • Slow on large dense models: Llama 3.3 70B Instruct at 9.2 tok/s
  • Slow prompt reading: A 32K-token prompt on Qwen3.8 27B waits 2.2 min for the first token
  • No CUDA: vLLM, AWQ, GPTQ and FP8 builds don't run; use GGUF or MLX
