Qwen3.8-27B-NVFP4
RadixArk · 2 tested configurations
- NVFP4 · 8K → 2K tokens
- Output throughput · includes prefill · 1 request
- 70.8tok/s
- Observed GPU occupancy
- 27.3GiB
- First token
- 633 ms
Test details
Total output tokens divided by the full request window, including prefill and queueing.
Occupancy includes engine buffers and reserved KV cache. It is not the minimum VRAM required by the model.
Reports combined counts reports, not inference requests. Request successes and failures are listed in each report.
