FP16 yes 468k 1586.7-1913.3 t/s ~29.1-35 (slow)

Q4 yes 470k 5666.7-6833.3 t/s ~103.8-125.2 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.

Yes. At Q4 it generates ~5666.7-6833.3 tok/s and fits up to 470k context; beyond that it spills to SSD swap and slows to ~103.8-125.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 470k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
