Can the NVIDIA H100 PCIe 80GB run Qwen1.5-32B?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen1.5-32B on the NVIDIA H100 PCIe 80GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 31k | 22.8-27.2 t/s | ~0.5-0.5 (slow) |
| Q8 | yes | 153k | 45.6-54.4 t/s | ~0.9-1.1 (slow) |
| Q4 | yes | 207k | 81.5-97.1 t/s | ~1.6-1.9 (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 Qwen1.5-32B?▶
Yes. At Q4 it generates ~81.5-97.1 tok/s and fits up to 207k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.6-1.9 tok/s.
How much context fits?▶
At Q4, up to about 207k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
