GPU is the key thing that empowers most of world-changing technologies we currently see: bitcoin, machine learning, AR/VR, CGI — all of them are executed via graphics cards.

This talk will give you a picture of what you can do with GPU on your mobile device. And of course we're going to pay attention to modern trending technologies such as neural networks.
