Rewrite the following text figuratively and beautifully: The figure represents Model Size vs. ImageNet Accuracy. EfficientNets significantly out-perform other ConvNets. In particular, EfficientNet-B7 achieves new state-of-the-art 84.4% top-1 accuracy but being 8.4x smaller and 6.1x faster than GPipe.  EfficientNet-B1 is 7.6x smaller and 5.7x faster than ResNet-152. Your response should contain less than 250 words.
