Can the Intel Arc B580 12GB run Unified-IO (XL)?

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

Unified-IO (XL) on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 56k 45.2-56.1 t/s ~4-4.9 (slow)
Q8 yes 101k 90.4-112.2 t/s ~7.9-9.8 (slow)
Q4 yes 121k 161.5-200.4 t/s ~14.2-17.6 (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 Unified-IO (XL)?โ–ถ

Yes. At Q4 it generates ~161.5-200.4 tok/s and fits up to 121k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~14.2-17.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 121k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
