DiT-XL/2 on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 125k 195.9-243.2 t/s ~17.2-21.3 (slow)
Q8 yes 135k 391.8-486.4 t/s ~34.4-42.7 (slow)
Q4 yes 140k 699.7-868.6 t/s ~61.4-76.2 (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 Intel Arc B580 12GB run DiT-XL/2?โ–ถ

Yes. At Q4 it generates ~699.7-868.6 tok/s and fits up to 140k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~61.4-76.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 140k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
