That board is probably being sold under cost. Look at how much stuff is crammed onto that PCB! It looks like there's a large BGA bridge chip (southbridge?) on there as well as a bunch of large perpipheral controllers. And what's with that odd chip-on-board module directly south of the Atom? It's missing from this previous picture of the board:

Compare this to a recent ARM quad-core A9 board, where a lot of the peripheral stuff is on the SoC (oh, and it has Wifi/Bt on board)

(Just a small plug for Boundary Devices here, their stuff is excellent. This is their new Nitrogen6_MAX, $249.).
