QuantFits?Max contextSpeedBeyond context
FP16 yes 1343k 280.6-343 t/s ~0.6-0.7 (slow)
Q8 yes 1426k 561.3-686 t/s ~1.1-1.4 (slow)
Q4 yes 1463k 1002.3-1225 t/s ~2-2.5 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.
