Can the NVIDIA GeForce RTX 4070 run Stable Diffusion 3.5 Medium?

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

Stable Diffusion 3.5 Medium on the NVIDIA GeForce RTX 4070

QuantFits?Max contextSpeedBeyond context
FP16 yes 69k 73.6-87.7 t/s ~5.8-7 (slow)
Q8 yes 107k 147.2-175.4 t/s ~11.7-13.9 (slow)
Q4 yes 124k 262.8-313.2 t/s ~20.9-24.9 (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 4070 run Stable Diffusion 3.5 Medium?โ–ถ

Yes. At Q4 it generates ~262.8-313.2 tok/s and fits up to 124k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~20.9-24.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 124k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
