Apple M4 Max 64GB for local AI

About 48 GB GPU-usable by default, enough for 70B models at Q4_K_M with a short context. The 546 GB/s bandwidth roughly matches an RTX 4070 Ti Super.

Among the 6 devices we track with about 48 GB of usable memory, the Apple M4 Max 64GB ranks 4 of 6 for text-generation speed, because generation speed follows memory bandwidth. Others in the same class: RTX 6000 Ada 48GB, L40S 48GB, RTX A6000 48GB, Apple M1 Max 64GB. They all hold the same models; the faster ones simply answer sooner.

Our picks for the Apple M4 Max 64GB

The model we would run first for each job, chosen from our recommendations by what fits fully with an 8K context. "Best quant" is the highest quality that fits; "max context" is at Q4_K_M or the native format.

Apple M4 Max 64GB for LLMs: common questions

Can the Apple M4 Max 64GB run Llama 3.3 70B?

Yes. Llama 3.3 70B needs about 43.2 GB at Q4_K_M with 8K context, and the best quality that fits is Q4_K_M.

Can the Apple M4 Max 64GB run Qwen 3 32B?

Yes. Qwen 3 32B needs about 21.4 GB at Q4_K_M with 8K context, and the best quality that fits is Q8_0.

Can the Apple M4 Max 64GB run Qwen 3 14B?

Yes. Qwen 3 14B needs about 10.5 GB at Q4_K_M with 8K context, and the best quality that fits is FP16 / BF16.

How fast is the Apple M4 Max 64GB for LLMs?

About 64 tokens per second for an 8B model at Q4_K_M, based on its 546 GB/s memory bandwidth. Larger models scale down roughly in proportion to their size.

How much of the 64 GB can the GPU use?

About 48.0 GB by default. You can raise it with sudo sysctl iogpu.wired_limit_mb=<MB> (resets on reboot), leaving at least 8 GB for macOS.
