Lenovo's K900 smartphone will be one of the first to utilize Intel's new dual-core Atom processor for mobile devices. The 32-nanometer chip roughly doubles the processing power found in the single-core Medfield CPU that powered the K800 handset and also includes a more powerful GPU, we're told.

The Lenovo handset is similar in size to the Samsung Galaxy Note II with a massive 5.5-inch, 1080p IPS display boasting 400 PPI. That's where the differences end, however, as the K900 is just 6.9mm thick and weighs only 5.7 ounces - making it the thinnest smartphone in its class.

Alongside the new Intel chip is 2GB of system memory, up to 16GB of storage, a 2-megapixel front-facing camera and a 13-megapixel f/1.8 rear shooter with two flashes. The rear camera uses a Sony CMOS Exmor backside illumination sensor that some say could produce photos on par with standalone digital cameras.

Unfortunately the K900 isn't quite ready for the big stage. The demo unit on hand at CES didn't even have an operating system loaded and if the K800 is any indication, we might not see the phone hit the US at all. Thus far, Lenovo has only publically announced plans to sell the handset in China starting in April.

The Atom Z2580 sounds impressive enough but we suspect that most are looking ahead to Intel's die shrink, the 22-nanometer chip that will use the same technology as Ivy Bridge. That processor, according to Intel's Erik Reid, will be ready at some point later this year.
