Apple M4 (16GB)

The Apple M4 (16GB) has 16 GB VRAM and 120 GB/s memory bandwidth. It can run 31 of our 70 tracked models natively in VRAM at 8k context.

With 16 GB LPDDR5X, the Apple M4 (16GB) is a laptop-tier GPU that can run 31 models natively. It handles 30B-class models at Q4 quantization.

Apple M4 (16GB): 16GB at 120 GB/s — base M4.

7B at Q4 native. 8B tight. ~5-8 t/s for 7B.

MLX support. 16GB minimum for practical LLM.

Frequently asked questions

How much VRAM does the Apple M4 (16GB) have?
The Apple M4 (16GB) has 16 GB of LPDDR5X with 120 GB/s memory bandwidth (unified system memory, shared between CPU and GPU).
What is the Apple M4 (16GB) best for?
With 16 GB of VRAM, the Apple M4 (16GB) handles smaller models (7B–14B) at Q4–Q5 quantization — ideal for entry-level local LLM experimentation and lightweight inference.
What LLMs can the Apple M4 (16GB) run locally?
The Apple M4 (16GB) can run 31 of the 70 open-weight models tracked by CanItRun natively in VRAM at 8k context. Top options include: Llama 3.1 8B Instruct at Q8_0, Llama 3.2 3B Instruct at BF16, Llama 3.2 1B Instruct at FP32.
Can the Apple M4 (16GB) run Llama 3.3 70B Instruct?
The Apple M4 (16GB) does not have enough VRAM to run Llama 3.3 70B Instruct. You would need more VRAM or a lower quantization level.
Can the Apple M4 (16GB) run Qwen 3.6 27B?
Yes. The Apple M4 (16GB) runs Qwen 3.6 27B natively in VRAM at Q2_K quantization, achieving approximately 13.5 tokens per second.
Can the Apple M4 (16GB) run Llama 3.1 8B Instruct?
Yes. The Apple M4 (16GB) runs Llama 3.1 8B Instruct natively in VRAM at Q8_0 quantization, achieving approximately 15 tokens per second.
