QuantFits?Max contextSpeedBeyond context
FP16 yes 2569k 491-600.1 t/s ~3.7-4.5 (slow)
Q8 yes 2621k 982.1-1200.3 t/s ~7.4-9.1 (slow)
Q4 yes 2643k 1753.7-2143.4 t/s ~13.2-16.2 (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.

Yes. At Q4 it generates ~1753.7-2143.4 tok/s and fits up to 2643k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~13.2-16.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 2643k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
