Can the Intel Arc B580 12GB run OpenPhenom-S/16?

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

OpenPhenom-S/16 on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 140k 742.7-922 t/s ~65.2-80.9 (slow)
Q8 yes 143k 1485.5-1844 t/s ~130.3-161.8 (slow)
Q4 yes 144k 2652.6-3292.9 t/s ~232.7-288.9 (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.

Can the Intel Arc B580 12GB run OpenPhenom-S/16?โ–ถ

Yes. At Q4 it generates ~2652.6-3292.9 tok/s and fits up to 144k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~232.7-288.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 144k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
