There appear to be 3 models of each the 13" and 15"
The differences are processor either an i5 or an i7 (i7 is faster)
How much memory the device has 6, 8 , or 12 GB (more is more)
Storage capacity and type. some have 256 GB Solid State Drives and some have 1 TB spinning Hard Drive
And then they apprea to have either Intel 520 or 620 graphics processors.
Then of course size of the display.
Other than that they are nearly identical.
