Llama 3.1 8B is a 8.03B-parameter model. At Q4_K_M it needs about 5.7 GB of memory. The NVIDIA RTX 5060 Ti 16GB has 15 GB usable, so it fits entirely in memory. Expect about 57 tokens/sec (42–72), with the first token after 0.3 s for a short prompt. This estimate is based on community benchmarks of this exact setup.
| Quantization | File size | Memory | Generation | First token | Source |
|---|---|---|---|---|---|
| Q4_K_M | 4.9 GB | Fits | 57 tok/s | 0.3 s | Measured |
| Q8_0 | 8.5 GB | Fits | 21 tok/s | 0.3 s | Derived |
| FP16 | 16.1 GB | Partial offload | 9.1 tok/s | 1.2 s | Projected |
