Can the Intel Arc A770 16GB run Stable Diffusion XL (SDXL)?

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

Stable Diffusion XL (SDXL) on the Intel Arc A770 16GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 98k 47.8-59.3 t/s ~3.4-4.2 (slow)
Q8 yes 150k 95.5-118.6 t/s ~6.8-8.5 (slow)
Q4 yes 173k 170.6-211.8 t/s ~12.2-15.1 (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 A770 16GB run Stable Diffusion XL (SDXL)?โ–ถ

Yes. At Q4 it generates ~170.6-211.8 tok/s and fits up to 173k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~12.2-15.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 173k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
