Can the AMD Instinct MI300X 192GB run DiffusionGemma 26B-A4B?

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

DiffusionGemma 26B-A4B on the AMD Instinct MI300X 192GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 470k 64.2-78.5 t/s ~0.5-0.6 (slow)
Q8 yes 569k 128.4-157 t/s ~1-1.2 (slow)
Q4 yes 613k 229.3-280.3 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.

Yes. At Q4 it generates ~229.3-280.3 tok/s and fits up to 613k 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 613k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
