Can the AMD Instinct MI325X run Viking?

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

Viking on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 641k 57.3-70 t/s ~0.4-0.5 (slow)
Q8 yes 767k 114.5-140 t/s ~0.8-0.9 (slow)
Q4 yes 822k 204.5-250 t/s ~1.4-1.7 (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 Viking?โ–ถ

Yes. At Q4 it generates ~204.5-250 tok/s and fits up to 822k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.4-1.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 822k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
