Can the NVIDIA A100 SXM4 80GB run NVIDIA Isaac GR00T N1.5 3B?
Yes — here's how fast and up to what context, with real measured numbers.
NVIDIA Isaac GR00T N1.5 3B on the NVIDIA A100 SXM4 80GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1009k | 248.1-295.7 t/s | ~4.9-5.8 (slow) |
| Q8 | yes | 1054k | 496.2-591.3 t/s | ~9.7-11.6 (slow) |
| Q4 | yes | 1075k | 886-1055.9 t/s | ~17.4-20.7 (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 NVIDIA A100 SXM4 80GB run NVIDIA Isaac GR00T N1.5 3B?▶
Yes. At Q4 it generates ~886-1055.9 tok/s and fits up to 1075k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~17.4-20.7 tok/s.
How much context fits?▶
At Q4, up to about 1075k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
