I have a 9.7" iPad Pro and 13" 2011 MacBook Pro with flash storage. The iPad Pro runs circles around the MBP; everything is faster and more fluid, especially graphically intensive tasks. I never realized how slow the MBP was until I got the iPad; the MBP chokes on its own animations, while I can't get the iPad to skip a beat. So at least in the real world tasks I'm doing, I can say the iPad Pro is faster.

Now people will rightfully point out that OS X =/= iOS, and that iOS is has significantly less overhead than OS X. These differences in the system software make real world speed testing an iPad and MacBook Pro worthless for determining which processor is more powerful. However, given how much faster the iPad is in real world usage than the MBP, intuitively I would not be surprised if more scientific tests showed the iPad A9X was indeed more powerful than the 2011 13" MBP i5.

So with this in mind, and knowing that the A10 is faster than the A9X, I wouldn't be surprised to find out that it was faster than a 2011 MBP. Your 2012 MBP (assuming 13") wouldn't be very much faster.
