| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 19 GB | 20.8 GB | Fits easily | ~8.2 tok/s |
| Q5_K_M | 24 GB | 25.8 GB | Fits easily | ~6.5 tok/s |
| Q8_0 | 36 GB | 37.8 GB | Fits easily | ~4.3 tok/s |
| FP16 | 67 GB | 68.8 GB | Fits easily | ~2.3 tok/s |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX Spark N1X (128 GB)'s 273 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.
