Can the Huawei Ascend 950DT run Stable Diffusion 3.5 Large?

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

Stable Diffusion 3.5 Large on the Huawei Ascend 950DT

QuantFits?Max contextSpeedBeyond context
FP16 yes 876k 160.5-195.1 t/s ~1.6-2 (slow)
Q8 yes 938k 321-390.1 t/s ~3.2-3.9 (slow)
Q4 yes 965k 573.2-696.6 t/s ~5.7-7 (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 Huawei Ascend 950DT run Stable Diffusion 3.5 Large?โ–ถ

Yes. At Q4 it generates ~573.2-696.6 tok/s and fits up to 965k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.7-7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 965k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
