Can the Apple M3 Max 64GB run BiRNA-BERT?

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

BiRNA-BERT on the Apple M3 Max 64GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 852k 1162.4-1401.7 t/s ~29.1-35 (slow)
Q8 yes 854k 2324.8-2803.4 t/s ~58.1-70.1 (slow)
Q4 yes 855k 4151.4-5006.1 t/s ~103.8-125.2 (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 64GB run BiRNA-BERT?โ–ถ

Yes. At Q4 it generates ~4151.4-5006.1 tok/s and fits up to 855k context; beyond that it spills to SSD swap and slows to ~103.8-125.2 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.
