BART-large on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 133k 325.5-404 t/s ~28.6-35.4 (slow)
Q8 yes 139k 651-808.1 t/s ~57.1-70.9 (slow)
Q4 yes 142k 1162.4-1443 t/s ~102-126.6 (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 BART-large?โ–ถ

Yes. At Q4 it generates ~1162.4-1443 tok/s and fits up to 142k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~102-126.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 142k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
