I’m not sure that’s actually a “plugin” type of widget. It’s a popular feature that’s built right into a lot of themes. Maybe if you could tell us the name of the theme in your screen-shot or site you found it on, someone could tell you if it’s a plugin or part of the theme.
Alternatively, you might search the plugins for something like this: http://wordpress.org/extend/plugins/search.php?q=popular+posts+widget&sort=

It belongs to “newspro magazine” from GabFire
I believe that’s probably a theme feature, rather than a plugin.
fanton is right.
The widget is called gab_tabs. It is from GabFire.
If you want something similar look for tabbed widgets.
