Comparing processing powers of iPads, and comparing those of iPads with that of a MacBook Pro.

Hi,

I have access to an iPad 2, an iPad 5 and a MacBook Pro. I'm thinking of trading the iPad 5 for the new iPad 7. I would do this because the extra processing power of the iPad 7 could be helpful to me. But before I do, I want to know just how much extra processing power the iPad 7 has with respect to the iPad 5; and also I want to know what the processing power of the iPad 7 is with respect to the iPad 2, the iPad 5 and to the MacBook Pro. The details for the specific MacBook Pro that I have access to I will leave at the bottom of this question so you can see. 

I contacted Apple to ask them about this but they said they were unable to disclose the information for the processing powers of iPads. However there are the specs. pages to look at. It seems that possibly the best indicator of an iPad's processing power is the quality of the chip of the iPad. The chips for the iPads 2, 5 and 7 are the A5 Chip, the A9 Chip and the A10 Fusion Chip respectively. It seems that the best indicator of the processing power of the MacBook Pro is the detail on the "About" page of the computer itself which reads -- 2.5GHz Intel Core i5 Processor -- but I have yet to contact Apple about this to be sure that this is the best indicator of the MacBook's processing power, though I know that they would be able to tell me this information. 

So here is my question: would you be able to clarify which are the best indicators of the processing powers of the iPads and of the MacBook Pro? Would you be able to spell out just what are the relative processing powers are of the iPads 2, 5 and 7 and of the MacBook Pro? It would be very useful for me if I could have these processing powers described in a ratio with respect to the MacBook; with the MacBook Pro as the most powerful, considered as maybe 1/1 or 100% processing power, and the iPads considered as fractions of that processing power -- 40%, 60%, 80%, for example.

By processing power I mean the ability of the computer or device to quickly perform functions and use apps such as a web browser, media apps, word processing apps, and so on. I have a wired 50Mb/s internet connection so internet connection speed isn't a factor for me in the device's processing speed. I know that the MacBook I use is very quick, more-or-less instantaneous, when using all ordinary functions. The iPad 5 is pretty quick, maybe as quick as a library computer. The iPad 2 I haven't been able to get the Ethernet connection to work for properly yet, but when I'm using it with Wi-Fi it is significantly slower than both the iPad 5 and the MacBook are when I am using them with the Wi-Fi (I don't use all three devices with the Wi-Fi at the same time, in case that's what you thought I meant).

Here are the details of the MacBook Pro, as the "About" page on the computer gives, so that you can see which one it is specifically: MacBook Pro; 13-inch, Mid 2012 (year); 2.5 GHz Intel Core i5 processor; 8GB 1600 MHz DDR3 Memory; Mac SSD Startup Disc; serial number C02JCFF0DTY3. On the bottom of the computer there is the year 2010 printed, which doesn't match with the 2012 year given on the "About" page, so I don't know what that means.

I thought I'd list the "About" page specifications for both my iPad 2 and for my iPad 5, in case that helps you answer my questions. So here they are:
