| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2553k | 136-164 t/s | ~1.7-2.1 (slow) |
| Q8 | yes | 2583k | 272-328 t/s | ~3.4-4.1 (slow) |
| Q4 | yes | 2597k | 485.7-585.7 t/s | ~6.1-7.3 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
