How can I compare two files in emacs, similar to vim's vimdiff?

Ediff works similarly: M-x ediff

Emacs ediff is no way comparable to vimdiff. I think emacs ediff is just a wrapper on Linux diff command. It is just highlighting the lines diff tool marks as changed.

I found vdiff give vimdiff like granularity. Follow instructions at the below link to use it.
