Hardware is definitely not the same. iPad Pro’s have double the ram and a faster memory bus for transferring files off or on the iPad. The A10x is a 6 core chip vs the A10’s 4 core design. The iPad Pro also has more then double the gpu compute capability so you would see a massive difference in photo and graphic design apps. An artist made a solid video about this where he choked the basic iPad on a big project and brush size and the Pro was smooth as butter.
