Can the NVIDIA B200 run BigGAN-deep 512x512?
Yes — here's how fast and up to what context, with real measured numbers.
BigGAN-deep 512x512 on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2669k | 25910.7-30879.9 t/s | ~129.6-154.4 (slow) |
| Q8 | yes | 2671k | 51821.4-61759.7 t/s | ~259.1-308.8 (slow) |
| Q4 | yes | 2671k | 92538.2-110285.2 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 B200 run BigGAN-deep 512x512?▶
Yes. At Q4 it generates ~92538.2-110285.2 tok/s and fits up to 2671k 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 2671k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
