FP16 yes 1015k 265.8-316.8 t/s ~5.2-6.2 (slow)
Q8 yes 1057k 531.6-633.5 t/s ~10.4-12.4 (slow)
Q4 yes 1076k 949.3-1131.3 t/s ~18.6-22.2 (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.
