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 5070 Ti 16GB has 15 GB usable, so it only fits with part of the model offloaded to system RAM, which slows it down. Expect about 12 tokens/sec (4.6–20), with the first token after 1.3 s for a short prompt. This estimate is projected from the hardware specs; no benchmarks exist yet.
| Quantization | File size | Memory | Generation | First token | Source |
|---|---|---|---|---|---|
| Q4_K_M | 16.8 GB | Partial offload | 12 tok/s | 1.3 s | Projected |
| Q8_0 | 28.6 GB | Partial offload | 3.7 tok/s | 1.3 s | Projected |
| FP16 | 53.8 GB | Doesn't fit | Won't run | — | — |
