Stable LM 2 12B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1280k 155.6-190.2 t/s ~1-1.3 (slow)
Q8 yes 1354k 311.3-380.4 t/s ~2.1-2.5 (slow)
Q4 yes 1387k 555.8-679.4 t/s ~3.7-4.5 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the AMD Instinct MI325X run Stable LM 2 12B?โ–ถ

Yes. At Q4 it generates ~555.8-679.4 tok/s and fits up to 1387k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.7-4.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1387k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
