Can the NVIDIA GeForce RTX 5090 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 NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 323k 192.4-229.3 t/s ~4.3-5.1 (slow)
Q8 yes 374k 384.8-458.5 t/s ~8.6-10.2 (slow)
Q4 yes 397k 687.1-818.8 t/s ~15.3-18.3 (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 NVIDIA GeForce RTX 5090 run Stable Diffusion XL (SDXL)?โ–ถ

Yes. At Q4 it generates ~687.1-818.8 tok/s and fits up to 397k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~15.3-18.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 397k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
