FP16 yes 371k 7.4-8.9 t/s ~0.1-0.1 (slow)
Q8 yes 512k 14.7-17.7 t/s ~0.2-0.2 (slow)
Q4 yes 574k 26.3-31.7 t/s ~0.3-0.4 (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 Ultra 192GB run Emu2?โ–ถ

Yes. At Q4 it generates ~26.3-31.7 tok/s and fits up to 574k context; beyond that it spills to SSD swap and slows to ~0.3-0.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 574k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
