FP16 yes 2580k 247.3-298.2 t/s ~3.1-3.7 (slow)
Q8 yes 2597k 494.5-596.4 t/s ~6.2-7.5 (slow)
Q4 yes 2604k 883.1-1064.9 t/s ~11-13.3 (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 SantaCoder?โ–ถ

Yes. At Q4 it generates ~883.1-1064.9 tok/s and fits up to 2604k context; beyond that it spills to SSD swap and slows to ~11-13.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 2604k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
