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

WizardCoder-15.5B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 774k 121.9-149 t/s ~0.8-1 (slow)
Q8 yes 834k 243.9-298.1 t/s ~1.6-2 (slow)
Q4 yes 860k 435.5-532.3 t/s ~2.9-3.5 (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.

FAQ

Can the AMD Instinct MI325X run WizardCoder-15.5B?โ–ถ

Yes. At Q4 it generates ~435.5-532.3 tok/s and fits up to 860k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.9-3.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 860k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
