Are there any weapons -- real or theoretical -- that have greater power than thermonuclear weapons?

Edit: To clarify, I am talking about man-made devices.

I'm not entirely sure what I meant by power either, I suppose what I meant was the destructive potential of a single device.

Depends on what you mean by power.  Antimatter weapons would theoretically be more powerful than nuclear weapons.  Even with the same energy released, the antimatter/matter collision would occur faster than the nuclear fission/nuclear fusion reactions used in current nuclear weapons.
