Testing was performed on models with weights quantized using [ModelOpt](https://nvidia.github.io/TensorRT-Model-Optimizer/#) and published by NVIDIA on the [Model Optimizer HuggingFace Collection](https://huggingface.co/collections/nvidia/model-optimizer-66aa84f7966b3150262481a4).

### FP4 Models:
```
### Hardware
The following GPU variants were used for testing:
- H100 SXM 80GB (DGX H100)
- H200 SXM 141GB (DGX H200)
- GH200 96GB HBM3 (480GB LPDDR5X)
- B200 180GB (DGX B200)
- GB200 192GB (GB200 NVL72)

Other hardware variants may have different TDP, memory bandwidth, core count, or other features leading to performance differences on these workloads.

In a majority of cases, we also use a higher KV cache percentage by setting `--kv_cache_free_gpu_mem_fraction 0.95` in the benchmark command. This allows us to obtain better performance than the default setting of `0.90`. We fall back to `0.90` if we hit an out of memory issue.
