FAQ

Can the AMD Instinct MI325X run Jamba 1.5-Large?โ–ถ

Yes. At Q4 it generates ~17-20.7 tok/s and fits up to 21k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.1-0.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 21k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
