FP16 yes 24k 10.9-13.2 t/s ~0.1-0.2 (slow)

Q4 yes 161k 39-47 t/s ~0.5-0.6 (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 Ultra 64GB run Aria?โ–ถ

Yes. At Q4 it generates ~39-47 tok/s and fits up to 161k context; beyond that it spills to SSD swap and slows to ~0.5-0.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 161k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
