| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1735k | 172151.9-207594.9 t/s | ~2151.9-2594.9 (slow) |
| Q8 | yes | 1735k | 344303.8-415189.9 t/s | ~4303.8-5189.9 (slow) |
| Q4 | yes | 1735k | 614828.2-741410.5 t/s | ~7685.4-9267.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
