Can the NVIDIA A100 SXM4 80GB run BigGAN-deep 512x512?
Yes — here's how fast and up to what context, with real measured numbers.
BigGAN-deep 512x512 on the NVIDIA A100 SXM4 80GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1097k | 6604-7870.5 t/s | ~129.6-154.4 (slow) |
| Q8 | yes | 1098k | 13208-15741 t/s | ~259.1-308.8 (slow) |
| Q4 | yes | 1099k | 23585.7-28109 t/s | ~462.7-551.4 (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 A100 SXM4 80GB run BigGAN-deep 512x512?▶
Yes. At Q4 it generates ~23585.7-28109 tok/s and fits up to 1099k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~462.7-551.4 tok/s.
How much context fits?▶
At Q4, up to about 1099k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
