Intel made its debut in the smartphone chip market with the unveiling of Lenovo K800 smartphone at the CES in Las Vegas, the first phone to run on Intel’s Medfield processor, and Lenovo was first manufacturer for this phone, not LG as we expected. The phone will use Intel’s 32-nanometer mobile chip technology, known as Medfield, part of Intel’s Atom line.

First off, the K800 is said to have a 4.5-inch 720p display and 1.6GHz processor but outside of a tip that it’ll be shipping to China Unicom in Q2 of this year, everything else surrounding it remains a mystery. The phone comes with Android 4.0 Ice Cream Sandwich operating system and runs with the new Lenovo LeOS user interface layered on top of it.

The Lenovo K800 Android smartphone is equipped with near-field communication (NFC). The 10mm thick device also features a smart 720p TFT display and sports an 8-megapixel camera that supports dual-LED flash. Other reports indicate that the K800 has Intel’s Wi-Di technology to wirelessly connect the handset to external displays. Other specs include a WCDMA HSPA+ 21Mbps wireless radio, Wi-Fi, Bluetooth 3.0 along with GPS and will be available on AT&T’s 3G network.

One surprise appearance was Motorola’s Sanjay Jha who appeared on stage to promise we’ll see Intel-based Motorola phones and tablets in the near future. To be more specific, it’s a multi-year and multi-device partnership with device and carrier announcements coming this summer.

We’ll bring you more info on the Lenovo K800 as it becomes available, as well as news from Intel’s other partnerships from their keynote. Stay tuned.
