I have developed a CNN model for image classification with TensorFlow and then converted it to TensorFlow-lite. I have done a comparison between the inferencing time in the tinker edge and RPi 4B 4GB. It turned out that on the RPi 4 the inferencing time is faster ~ 1sec compared to the tinker edge r which is ~ 2sec. How is that possible. shouldn't the tinker edge have an AI accelerator unit? Am I missing something?
I would please appreciate your help.
thanks
