minChatGPT on the Intel Arc B580 12GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 96k 80.7-100.2 t/s ~7.1-8.8 (slow)
Q8 yes 121k 161.4-200.3 t/s ~14.2-17.6 (slow)
Q4 yes 132k 288.2-357.7 t/s ~25.3-31.4 (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 minChatGPT?โ–ถ

Yes. At Q4 it generates ~288.2-357.7 tok/s and fits up to 132k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~25.3-31.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 132k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
