Can the NVIDIA H100 PCIe 80GB run SANA 1.5 4.8B?

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

SANA 1.5 4.8B on the NVIDIA H100 PCIe 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 954k 152.1-181.3 t/s ~3-3.6 (slow)
Q8 yes 1027k 304.2-362.5 t/s ~6.1-7.3 (slow)
Q4 yes 1059k 543.2-647.3 t/s ~10.9-12.9 (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 H100 PCIe 80GB run SANA 1.5 4.8B?โ–ถ

Yes. At Q4 it generates ~543.2-647.3 tok/s and fits up to 1059k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~10.9-12.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1059k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
