QuantFits?Max contextSpeedBeyond context
FP16 yes 1715k 418.5-504.6 t/s ~5.2-6.3 (slow)
Q8 yes 1725k 836.9-1009.2 t/s ~10.5-12.6 (slow)
Q4 yes 1729k 1494.5-1802.2 t/s ~18.7-22.5 (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 M1 Ultra 128GB run ProtRNA?โ–ถ

Yes. At Q4 it generates ~1494.5-1802.2 tok/s and fits up to 1729k context; beyond that it spills to SSD swap and slows to ~18.7-22.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1729k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
