Can the AMD Instinct MI325X run Qwen3-8B?

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

Qwen3-8B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1660k 230.5-281.7 t/s ~1.5-1.9 (slow)
Q8 yes 1723k 461-563.4 t/s ~3.1-3.8 (slow)
Q4 yes 1750k 823.2-1006.1 t/s ~5.5-6.7 (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 Qwen3-8B?โ–ถ

Yes. At Q4 it generates ~823.2-1006.1 tok/s and fits up to 1750k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.5-6.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1750k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
