| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 841k | 371.3-447.7 t/s | ~6.8-8.2 (slow) |
| Q8 | yes | 848k | 742.6-895.4 t/s | ~13.6-16.4 (slow) |
| Q4 | yes | 852k | 1326-1599 t/s | ~24.3-29.3 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
