QuantFits?Max contextSpeedBeyond context
FP16 yes 545k 61.9-74.6 t/s ~1.1-1.4 (slow)
Q8 yes 591k 123.8-149.2 t/s ~2.3-2.7 (slow)
Q4 yes 611k 221-266.5 t/s ~4-4.9 (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 48GB run SimpleFold?โ–ถ

Yes. At Q4 it generates ~221-266.5 tok/s and fits up to 611k context; beyond that it spills to SSD swap and slows to ~4-4.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 611k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
