Question 1

Can I run Gemma 3n E2B on a Apple M4 Max?

Accepted Answer

Yes — Apple M4 Max runs Gemma 3n E2B fully on GPU at the FP16 quantization. Full GPU inference — 128 GB VRAM meets the 5.2 GB recommendation.

Question 2

What quantization of Gemma 3n E2B should I use on a Apple M4 Max?

Accepted Answer

For 128 GB VRAM on the Apple M4 Max, the FP16 variant is the best fit. Estimated ~136.5 tokens/sec on the FP16 quantization.

Question 3

How fast does Gemma 3n E2B run on Apple M4 Max?

Accepted Answer

Roughly 136.5 tokens/sec for FP16. Real speed depends on context length, backend (Ollama, llama.cpp, LM Studio), and KV cache size.

Question 4

What if Apple M4 Max is not enough for Gemma 3n E2B?

Accepted Answer

Try a smaller quantization variant or run on CPU + RAM with the trade-off of slower generation.
