| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 777k | 52.3-63.1 t/s | ~1.3-1.6 (slow) |
| Q8 | yes | 816k | 104.6-126.2 t/s | ~2.6-3.2 (slow) |
| Q4 | yes | 834k | 186.8-225.3 t/s | ~4.7-5.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
