Hardware for Running Gemma 3 12B Locally
The mid-size Gemma 3 — solid general-purpose quality with a long context window, fitting mid-range hardware at Q4.
Quick answer
Gemma 3 12B (12B params) needs about 8 GB of memory at Q4 and 29 GB at full FP16 precision — both estimates including runtime overhead. It fits 15 boxes in our catalog, starting at the MAGICNUC AS1 Mini PC (Ryzen 5 3550H) ($229 – $299).
Estimated Memory Requirements
Estimated from the 12B parameter count (quantization × bytes/param + ~20% runtime overhead), not measured. MoE models load by total parameters.
| Precision | Est. Memory | Notes |
|---|---|---|
| FP16 (full precision) | ~29 GB | Best quality, highest memory usage |
| Q8 (8-bit quantized) | ~15 GB | Near-lossless quality, good balance |
| Q4 (4-bit quantized) | ~8 GB | Smallest footprint, slight quality loss |
