The MacBook Pro 16" M5 Pro is a 48 GB laptop with more memory than speed: it runs 14B and 35B MoE models well. Among 48 GB machines, only the M5 Max, M4 Max and M3 Max write faster. macOS keeps about 3.5 GB, leaving 44.5 GB for models. Prompt reading is its weak spot: a 4K-token prompt waits 6.0 s before the first word on Qwen3.6 35B A3B. M5 Pro generation, released 2026.
MacBook Pro 16" M5 Pro strengths and weaknesses
Strengths
- Runs 35B MoE models: Qwen3.6 35B A3B at 46.5 tok/s in 22 GB
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 5.4 tok/s, Qwen3.8 27B at 12.3 tok/s
- Slow prompt reading: A 32K-token prompt on Qwen3.6 35B A3B waits 48.0 s 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 Qwen3.5 9B.
Output speed depends on memory bandwidth (307 GB/s). Grey rows need more than the 44.5 GB available.

Pro generations: writing vs compute
M1 Pro → M5 ProWriting speed follows memory bandwidth and barely moved: 22.0 to 33.8 tok/s since the M1 Pro. Compute, which sets how fast prompts are read, grew 3.1×. Indexed to the M1 Pro; speeds on Qwen3.5 9B, same 32 GB.
