M-x ediff  :)

You can diff two files, a file with a buffer... Side by side, top
to bottom, whatever.

There is documentation for the ediff mode. Try C-h i ediff, perhaps it is
installed on your machine. If not (and if you want to suffer the whims
of your browser ;-) it's on the internets [1] too.

Cheers
