Can the Apple M4 Max 64GB run UnifiedQA?

Yes โ€” here's how fast and up to what context, with real measured numbers.

UnifiedQA on the Apple M4 Max 64GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 208k 16.9-20.4 t/s ~0.3-0.4 (slow)
Q8 yes 275k 33.8-40.7 t/s ~0.6-0.7 (slow)
Q4 yes 305k 60.3-72.7 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 M4 Max 64GB run UnifiedQA?โ–ถ

Yes. At Q4 it generates ~60.3-72.7 tok/s and fits up to 305k 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 305k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
