The Barcelona will use 65nm, as opposed to today's 90nm. The thermal output is expected to be identical to today's dual core Athlon 64s due to that die shrink. Barcelonas use identical voltage to today's dual core Athlon 64s. They also use the same socket.
It's very believable, you just have to stop and look at the technical specifications for a moment.
