Which Mxnet Image Is the Fastest

As shown in NVIDIA Data Center Deep Learning Product Performance, the latest performance of Resnet50v1.5 in MxNet reached 2751img/sec. But it doesn’t indicate the version of the container and server. And the link of ResNet-50 v1.5 is not updated., so I tried the lastest mxnet:21.02-py3 which reached 1734 img/sec in a single A100 as issue shows in DeepLearningExamples.So I’m confused whether the hardware I’m using is too different or the NGC version is not the right one.
