UnifiedQA on the Apple M3 Max 128GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 560k 12.4-14.9 t/s ~0.3-0.4 (slow)
Q8 yes 627k 24.7-29.8 t/s ~0.6-0.7 (slow)
Q4 yes 656k 44.2-53.2 t/s ~1.1-1.3 (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 M3 Max 128GB run UnifiedQA?โ–ถ

Yes. At Q4 it generates ~44.2-53.2 tok/s and fits up to 656k context; beyond that it spills to SSD swap and slows to ~1.1-1.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 656k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
