QuantFits?Max contextSpeedBeyond context
FP16 yes 341k 47.7-57.5 t/s ~0.6-0.7 (slow)
Q8 yes 385k 95.4-115.1 t/s ~1.2-1.4 (slow)
Q4 yes 404k 170.4-205.5 t/s ~2.1-2.6 (slow)

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

FAQ

Can the Apple M2 Ultra 64GB run DeciLM 6B?โ–ถ

Yes. At Q4 it generates ~170.4-205.5 tok/s and fits up to 404k context; beyond that it spills to SSD swap and slows to ~2.1-2.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 404k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
