   * GPU Speed measures end-to-end time per image averaged over 5000 COCO val2017 images using a V100 GPU with batch size 32, and includes image preprocessing, PyTorch FP16 inference, postprocessing and NMS. 
   * EfficientDet data from [google/automl](https://github.com/google/automl) at batch size 8.
