M4 Pro vs M4 Max for LLMs: When Does Max Make Sense?

Both M4 Pro and M4 Max power MacBook Pro and Mac Studio configurations. The M4 Max costs significantly more but offers higher memory bandwidth and more GPU cores. For local AI, the question is whether those extras translate to meaningful performance gains, or if M4 Pro is already enough.

Verdict

Tie

M4 Max delivers about 75% faster inference than M4 Pro on the same 8B Q4 model (top Max bin), thanks to 2x memory bandwidth and more GPU cores. It is worth the upgrade only if you regularly run 30B+ models or need maximum speed. For 7B-14B models, M4 Pro is more than sufficient.

Detailed analysis

Memory Bandwidth

Apple M4 Max

M4 Max has exactly double the memory bandwidth of M4 Pro at its top 40-core GPU configuration; the base 32-core M4 Max bin drops to about 410 GB/s. Since LLM inference is memory-bandwidth-bound, this directly translates to faster token generation.

Max RAM

Apple M4 Max

M4 Max supports 128 GB, enabling 70B models that cannot fit on M4 Pro. This is the biggest practical difference for large model users.

GPU Cores

Apple M4 Max

Twice the GPU cores means faster prompt processing and parallel workloads. The impact on pure token generation is less than memory bandwidth.

Price

Apple M4 Pro

M4 Pro costs noticeably less. For 7B-14B models, the performance is already excellent, making the extra cost hard to justify.

Speed on 8B Models

Apple M4 Max

M4 Max is faster even on small models, but 40 tok/s from M4 Pro is already real-time for chat. The difference matters more for batch processing.

Frequently asked questions

Is M4 Max worth it just for AI workloads?
Only if you run 30B+ models regularly. For 7B-14B models, M4 Pro is fast enough. The M4 Max is worth it if you also benefit from the extra GPU and memory for video editing or 3D work.
Can M4 Pro run 70B models?
No. M4 Pro maxes out at 48 GB RAM, which is not enough for 70B Q4 models (need ~42 GB load + OS overhead). You need M4 Max with 64 GB+ for 70B.
How much faster is M4 Max for inference?
Roughly 75% faster on a 14B Q4 model, primarily due to 2x memory bandwidth. Expect around 42 tok/s on M4 Max vs 24 tok/s on M4 Pro.
