FP16 yes 2590k 618.3-755.7 t/s ~4.7-5.7 (slow)
Q8 yes 2631k 1236.7-1511.5 t/s ~9.3-11.4 (slow)
Q4 yes 2649k 2208.3-2699.1 t/s ~16.7-20.4 (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.
