QuantFits?Max contextSpeedBeyond context
FP16 yes 219k 38.9-47.5 t/s ~1.8-2.2 (slow)
Q8 yes 272k 77.8-95 t/s ~3.6-4.4 (slow)
Q4 yes 296k 138.9-169.7 t/s ~6.4-7.9 (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.
