Can the NVIDIA GeForce RTX 5090 run Hunyuan-DiT?

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

Hunyuan-DiT on the NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 381k 436.1-519.7 t/s ~9.7-11.6 (slow)
Q8 yes 403k 872.1-1039.4 t/s ~19.5-23.2 (slow)
Q4 yes 414k 1557.3-1856 t/s ~34.8-41.4 (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.

FAQ

Can the NVIDIA GeForce RTX 5090 run Hunyuan-DiT?โ–ถ

Yes. At Q4 it generates ~1557.3-1856 tok/s and fits up to 414k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~34.8-41.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 414k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
