FP16 yes 1619k 71.6-86.3 t/s ~0.9-1.1 (slow)
Q8 yes 1677k 143.2-172.6 t/s ~1.8-2.2 (slow)
Q4 yes 1702k 255.6-308.3 t/s ~3.2-3.9 (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 ~255.6-308.3 tok/s and fits up to 1702k context; beyond that it spills to SSD swap and slows to ~3.2-3.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1702k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
