I always using :wq to save a file. Today, I came to know that :x can be used to do that. But I didn't notice it in any vi-tutorial or vi-quick-reference. Is there any difference between these two commands?

The difference between those twos is very simple: :x saves changes to the file only it it has been modified, while :wq changes the modification time no matter what.
Press Esc to enter Command mode, and then type :wq to write and quit the file. The other, quicker option is to use the keyboard shortcut ZZ to write and quit. In Vi, write means save, and quit means exit.
:Wq (Save edit operation and exit): Writing even if the file has not been modified, and updates the modification time of the file. :Wq! (Save edit and force exit): Mandatory write to file and forced exit, ! for enforcement. Some files are set to read-only.
:w - Saves the file you are working on. :w [filename] - Allows you to save your file with the name you've defined. :wq - Save your file and close Vim. :q! - Quit without first saving the file you were working on.

:[range]x[it][!] [++opt] [file]
Like ":wq", but write only when changes have been
made.
When 'hidden' is set and there are more windows, the
current buffer becomes hidden, after writing the file.
