| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1720k | 161.3-197.1 t/s | ~6.3-7.7 (slow) |
| Q8 | yes | 1727k | 322.6-394.2 t/s | ~12.6-15.4 (slow) |
| Q4 | yes | 1731k | 576-704 t/s | ~22.5-27.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
