| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 470k | 2266.7-2733.3 t/s | ~75.6-91.1 (slow) |
| Q8 | yes | 471k | 4533.3-5466.7 t/s | ~151.1-182.2 (slow) |
| Q4 | yes | 471k | 8095.2-9761.9 t/s | ~269.8-325.4 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
