| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1717k | 453.3-546.7 t/s | ~5.7-6.8 (slow) |
| Q8 | yes | 1726k | 906.7-1093.3 t/s | ~11.3-13.7 (slow) |
| Q4 | yes | 1730k | 1619-1952.4 t/s | ~20.2-24.4 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
