Intel has joined forces with Lenovo and Motorola to launch the tech giant's long-awaited first smartphones.

The Lenovo K800, which was unveiled at the Consumer Electronics Show taking place in Las Vegas this week, runs Google's Android operating system and is powered by the Intel Atom Z2460 processor platform, which was previously dubbed 'Medfield' and according to Intel has been specifically designed for smartphones and tablet PC and delivers "leading performance with competitive, energy efficiency". The handset will initially be made available in China in Q2, with launches in the UK, Europe and the US to follow shortly afterwards.

"The best of Intel computing is coming to smartphones," said Intel President and CEO Paul Otellini.

"Our efforts with Lenovo and Motorola Mobility will help to establish Intel processors in smartphones and provide a solid foundation from which to build in 2012 and into the future."

Motorola Mobility and Intel have entered into a multi-year, multi-strategy relationship that will see smartphones and tablets using Intel's processors and running Google Android to be shipped in the second half of 2012.

"We are delighted to be partnering with Intel to deliver smartphones and tablets based on Intel's Atom processor to consumers and businesses," said Sanjay Jha, Chairman and CEO, Motorola Mobility.

"Though there are five billion mobile subscribers in the world, less than 800 million are using a smartphone today. With Android as the leading smartphone OS globally and advancements in computing technology we see tremendous opportunity for the converged devices market."

Intel also its demoed its Smartphone Reference Design that is hopes will "shrink device development time and costs for phone OEMs and carriers". The handset features a 4.03in LCD touchscreen, and two cameras that will capture 15 images up to 8Mp in quality in less than a second.
