Can the AMD Instinct MI325X run Mamba2-Hybrid?

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

Mamba2-Hybrid on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1653k 218.2-266.7 t/s ~1.5-1.8 (slow)
Q8 yes 1719k 436.5-533.5 t/s ~2.9-3.6 (slow)
Q4 yes 1748k 779.4-952.7 t/s ~5.2-6.4 (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 Mamba2-Hybrid?โ–ถ

Yes. At Q4 it generates ~779.4-952.7 tok/s and fits up to 1748k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.2-6.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1748k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
