|---|---|---|---|---|
| FP16 | yes | 1734k | 13438.7-16205.5 t/s | ~168-202.6 (slow) |
| Q8 | yes | 1735k | 26877.5-32411.1 t/s | ~336-405.1 (slow) |
| Q4 | yes | 1735k | 47995.5-57876.9 t/s | ~599.9-723.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
