Can the AMD Instinct MI325X run SANA 1.5 4.8B?

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

SANA 1.5 4.8B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 3424k 393.8-481.3 t/s ~2.6-3.2 (slow)
Q8 yes 3498k 787.5-962.5 t/s ~5.3-6.4 (slow)
Q4 yes 3530k 1406.3-1718.8 t/s ~9.4-11.5 (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.

Can the AMD Instinct MI325X run SANA 1.5 4.8B?โ–ถ

Yes. At Q4 it generates ~1406.3-1718.8 tok/s and fits up to 3530k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~9.4-11.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 3530k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
