Can the NVIDIA GeForce RTX 3070 run Stable Diffusion (LDM-KL-8-G)?

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

Stable Diffusion (LDM-KL-8-G) on the NVIDIA GeForce RTX 3070

QuantFits?Max contextSpeedBeyond context
FP16 yes 45k 112.8-134.4 t/s ~10.1-12 (slow)
Q8 yes 67k 225.5-268.8 t/s ~20.1-24 (slow)
Q4 yes 77k 402.8-480 t/s ~36-42.9 (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 3070 run Stable Diffusion (LDM-KL-8-G)?โ–ถ

Yes. At Q4 it generates ~402.8-480 tok/s and fits up to 77k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~36-42.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 77k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
