Can the NVIDIA GeForce RTX 3090 run DiT-XL/2?

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

DiT-XL/2 on the NVIDIA GeForce RTX 3090

FP16 yes 293k 506.1-603.2 t/s ~21.6-25.8 (slow)
Q8 yes 304k 1012.3-1206.4 t/s ~43.3-51.6 (slow)
Q4 yes 308k 1807.6-2154.3 t/s ~77.2-92.1 (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 NVIDIA GeForce RTX 3090 run DiT-XL/2?โ–ถ

Yes. At Q4 it generates ~1807.6-2154.3 tok/s and fits up to 308k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~77.2-92.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 308k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
