Nano X2 comes the Eden X2, or what VIA is calling "the world's most power-efficient" fanless dual-core processor. While we've yet to see any official numbers, the original Eden did 500MHz on one watt of power, so we should see similarly thrifty specs here. Aside from that, the unit houses two 64-bit cores in a 21 x 21 millimeter package, is compatible with Windows CE and Linux operating systems, and was built using a 40-nanometer manufacturing process. The Eden X2 made its debut at the World Embedded conference this week, and should make it to the real world by the end of Q2. Full PR after the break.
