The company announced plans in 2009 to collaborate with LG on smartphones using Intel's Moorestown chipsets, and in 2010 LG showed off the Atom-powered GW990 smartphone, but later insisted that this was just a concept phone not destined for full production.
The first smartphone powered by an Intel chipset will go on sale in India on Monday, the chip maker has revealed.
The Android-based device, named the XOLO 900, has been produced by Indian handset vendor Lava International. It will retail for around 22,000 rupees (€321), and runs a 1.6 GHz Atom processor with a 400 MHz graphics clock. The chip is capable of using Intel's hyper threading technology, and the firm claims the handset can provide up to 8 hours of talk time and 5 hours of 3G browsing on a single charge.
Intel and Lava first announced their partnership to build an Intel smartphone at February's Mobile World Congress in Barcelona.
The handset has a 4.03-inch screen and an 8-megapixel camera. At launch, it will use Android Gingerbread, with an over-the-air update planned to upgrade to Ice Cream Sandwich.
Intel is believed to have been trying for some time to expand beyond the desktop CPU market - where it dominates - into smartphones and tablets, where ARM architecture rules the day.
