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

DiffusionGemma 26B-A4B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 694k 72.7-88.8 t/s ~0.5-0.6 (slow)
Q8 yes 794k 145.4-177.7 t/s ~1-1.2 (slow)
Q4 yes 837k 259.6-317.3 t/s ~1.7-2.1 (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 DiffusionGemma 26B-A4B?โ–ถ

Yes. At Q4 it generates ~259.6-317.3 tok/s and fits up to 837k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.7-2.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 837k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
