QuantFits?Max contextSpeedBeyond context
FP16 yes 62k 2.9-3.5 t/s ~0.1-0.1 (slow)
Q8 yes 204k 5.8-7 t/s ~0.1-0.2 (slow)
Q4 yes 267k 10.4-12.5 t/s ~0.3-0.3 (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 M3 Max 128GB run GRITLM 8x7B?โ–ถ

Yes. At Q4 it generates ~10.4-12.5 tok/s and fits up to 267k context; beyond that it spills to SSD swap and slows to ~0.3-0.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 267k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
