| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 83k | 3.8-4.6 t/s | ~0-0.1 (slow) |
| Q8 | yes | 303k | 7.6-9.1 t/s | ~0.1-0.1 (slow) |
| Q4 | yes | 400k | 13.5-16.3 t/s | ~0.2-0.2 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
