Gemma 4 12B is a 11.96B-parameter model. At Q4_K_M it needs about 7.9 GB of memory. The NVIDIA RTX 3060 12GB has 11 GB usable, so it fits entirely in memory. Expect about 22 tokens/sec (11–33), with the first token after 0.4 s for a short prompt. This estimate is interpolated from benchmarks of similar setups.
| Quantization | File size | Memory | Generation | First token | Source |
|---|---|---|---|---|---|
| Q4_K_M | 7.1 GB | Fits | 22 tok/s | 0.4 s | Derived |
| Q8_0 | 12.7 GB | Partial offload | 9.0 tok/s | 1.3 s | Projected |
| FP16 | 23.8 GB | Partial offload | 2.9 tok/s | 1.3 s | Projected |
