MSA Transformer on the Apple M2 Max 64GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 853k 1360-1640 t/s ~34-41 (slow)
Q8 yes 854k 2720-3280 t/s ~68-82 (slow)
Q4 yes 855k 4857.1-5857.1 t/s ~121.4-146.4 (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 Max 64GB run MSA Transformer?โ–ถ

Yes. At Q4 it generates ~4857.1-5857.1 tok/s and fits up to 855k context; beyond that it spills to SSD swap and slows to ~121.4-146.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 855k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
