Can the AMD Instinct MI300X 192GB run LFM2.5-ColBERT-350M?

Yes โ€” here's how fast and up to what context, with real measured numbers.

LFM2.5-ColBERT-350M on the AMD Instinct MI300X 192GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 2662k 4770-5830 t/s ~36-44 (slow)
Q8 yes 2667k 9540-11660 t/s ~72-88 (slow)
Q4 yes 2669k 17035.7-20821.4 t/s ~128.6-157.1 (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 MI300X 192GB run LFM2.5-ColBERT-350M?โ–ถ

Yes. At Q4 it generates ~17035.7-20821.4 tok/s and fits up to 2669k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~128.6-157.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 2669k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
