The MacBook Pro 14" M4 Max is one of the fastest 48 GB machines: it runs 27–35B models well. Among 48 GB machines, only the M5 Max write faster. macOS keeps about 3.5 GB, leaving 44.5 GB for models. With 34 TFLOPS it reads long prompts faster than most 48 GB machines: a 4K-token prompt takes 33 s. M4 Max generation, released 2024; the newer M5 Max writes 6% faster with 2.0× the compute.
MacBook Pro 14" M4 Max strengths and weaknesses
Strengths
- Runs 35B MoE models: Qwen3.6 35B A3B at 64.2 tok/s in 22 GB
- Room for long context: Qwen3.8 27B at Q4 uses 17.9 GB, leaving 26.6 GB free
Weaknesses
- 120B MoE models don't fit: GPT OSS 120B needs 70.8 GB at Q4 vs 44.5 GB usable here
- Slow on large dense models: Llama 3.3 70B Instruct at 9.6 tok/s
- Slow prompt reading: A 32K-token prompt on Qwen3.8 27B waits 4.4 min for the first token
- No CUDA: vLLM, AWQ, GPTQ and FP8 builds don't run; use GGUF or MLX
Memory for models
44.5 GB of 48 GB120B MoE models need 70.8 GB at Q4, more than the 44.5 GB available.
Other memory sizes of the same machine first, then machines and GPUs people weigh against it, each with the one reason it is worth a look. Speeds on Qwen3.6 35B A3B.
Output speed depends on memory bandwidth (546 GB/s). Grey rows need more than the 44.5 GB available.

Max generations: writing vs compute
M1 Max → M5 MaxWriting speed follows memory bandwidth and barely moved: 54.5 to 67.8 tok/s since the M1 Max. Compute, which sets how fast prompts are read, grew 4.4×. Indexed to the M1 Max; speeds on Qwen3.6 35B A3B, same 32 GB.
