Question

Upgrading Processor on Late 2015 iMac 27

Late 2015 iMac 27 Retina 5k

I have two iMac 27's. One has an an Intel Core i7 processor.

The other one has an Intel Core i5 processor.

The speed difference is noticeable, so I'd like to upgrade the i5 to an i7 processor. Can someone please give me the i7 processor model number?

Can it be swapped plug & play, with no other concerns?
