Gemma 3n E4B — VRAM, speed & local setup
Written by Jakub Rusinowski · Last updated
The full-power Gemma 3n variant. Processes text, images, audio, and video. Runs on devices with 4 GB RAM, including mid-range phones and all laptops.
Gemma 3n E4B needs about 6 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.
VRAM and speed by quantization
Quoted against NVIDIA RTX 4090 (24 GB). Weights plus overhead only: this model's architecture is unpublished, so no KV cache is added.
| Quant | Memory | VRAM | Speed (est.) | Fit |
|---|---|---|---|---|
| Q2_K 2.63 bpw | 3.4 GB | ~213 tok/s | Fits | |
| Q3_K_M 3.41 bpw | 4.1 GB | ~193 tok/s | Fits | |
| Q4_K_M 4.83 bpw | 5.5 GB | ~164 tok/s | Fits | |
| Q5_K_M 5.67 bpw | 6.4 GB | ~151 tok/s | Fits | |

Other Gemma 3n sizes
Gemma 3n E4B — frequently asked questions
How much VRAM does Gemma 3n E4B need?
About 6 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.
Does Gemma 3n E4B run on an RTX 4090 (24 GB)?
Yes. Gemma 3n E4B needs about 6 GB at Q4_K_M, inside a 24 GB card, at an estimated 164 tokens/sec.
How do I run Gemma 3n E4B locally?
Install Ollama and run `ollama run gemma3n:e4b`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
What other sizes does Gemma 3n come in?
Gemma 3n E2B (4 GB), Gemma 3n E4B (6 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
