Can the NVIDIA GeForce RTX 4080 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 4080

QuantFits?Max contextSpeedBeyond context
FP16 yes 181k 398-474.3 t/s ~21.6-25.8 (slow)
Q8 yes 191k 796-948.6 t/s ~43.3-51.6 (slow)
Q4 yes 196k 1421.4-1694 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 4080 run DiT-XL/2?โ–ถ

Yes. At Q4 it generates ~1421.4-1694 tok/s and fits up to 196k 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 196k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
