Qwen 3.6/3.8 27B is a 27.78B-parameter model. At Q4_K_M it needs about 17.6 GB of memory. The NVIDIA RTX 3090 24GB has 22 GB usable, so it fits entirely in memory. Expect about 22 tokens/sec (8.2–37), with the first token after 0.3 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 | 16.8 GB | Fits | 22 tok/s | 0.3 s | Derived |
| Q8_0 | 28.6 GB | Partial offload | 5.9 tok/s | 1.3 s | Projected |
| FP16 | 53.8 GB | Doesn't fit | Won't run | — | — |
