Hardware for Running Gemma 3 27B Locally
The largest Gemma 3 — frontier-adjacent quality for a dense open model, comfortably runnable on a single large-memory box.
Quick answer
Gemma 3 27B (27B params) needs about 17 GB of memory at Q4 and 65 GB at full FP16 precision — both estimates including runtime overhead. It fits 13 boxes in our catalog, starting at the GMKtec M6 Ultra Mini PC (Ryzen 7 7640HS, 32GB) ($569).
Estimated Memory Requirements
Estimated from the 27B parameter count (quantization × bytes/param + ~20% runtime overhead), not measured. MoE models load by total parameters.
| Precision | Est. Memory | Notes |
|---|---|---|
| FP16 (full precision) | ~65 GB | Best quality, highest memory usage |
| Q8 (8-bit quantized) | ~33 GB | Near-lossless quality, good balance |
| Q4 (4-bit quantized) | ~17 GB | Smallest footprint, slight quality loss |
