TensorFlow Lite or hardware acceleration sdk for mobile (like Arm NN SDK)

Hello,

I’m trying to develop an android application that uses a deep learning algorithm on the mobile itself, i.e. locally.

I want to make it run on GPU, and from what I understand there are actually TFLite delegates that can help me achieve that. However, after a little research I found out that I can also use the Arm NN SDK with TFLite. Will the use of Arm NN actually make the application run faster, or is TFLite by itself a good choice?

Thanks in advance!
