QuantFits?Max contextSpeedBeyond context
FP16 yes 602k 170.1-207.9 t/s ~7.9-9.6 (slow)
Q8 yes 627k 340.2-415.8 t/s ~15.8-19.3 (slow)
Q4 yes 637k 607.5-742.5 t/s ~28.1-34.4 (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.
