Estimate at 4-bit with 32K context, 64 GB of DDR5 for offload. Speed ≈ memory bandwidth × 78% ÷ data read per token, plus a fixed cost per token, calibrated on 44 real llama.cpp tests; typical error about ±10%. Compare all GPUs.
GPU memory needed
| Level | 8K context | 32K context | 128K context | Quality vs full |
|---|---|---|---|---|
| Q3_K_M | 3.1 GB | 3.9 GB | 7.1 GB | +10.5% noticeable loss |
| Q4_K_M | 3.6 GB | 4.4 GB | 7.6 GB | +2.8% small loss |
| Q5_K_M | 4.1 GB | 4.9 GB | 8.1 GB | +0.9% very small loss |
| Q6_K | 4.6 GB | 5.4 GB | 8.6 GB | +0.3% near-lossless |
| Q8_0 | 5.6 GB | 6.5 GB | 9.7 GB | ≈ 0% same as full |
| F16 | 9.9 GB | 11 GB | 14 GB | ≈ 0% same as full |
Weights + context cache (from the model's architecture) + runtime. Quality: increase in perplexity against the full model, from llama.cpp tests, scaled by model size. Simulate your own setup.
