--FILE--Pedestrians walk past an advertisement for Intel Core i5 at a metro station in Shanghai, China, 25 May 2013. Intel Corp., struggling to break into the market for chips that run tablets, is teaming up with Chinas Fuzhou Rockchip Electronics Co. on a new product for mobile devices. The chipmakers signed an agreement to jointly offer a quad-core processor and integrated modem called Sofia, which will be available in the first half of 2015, Intel said today in a statement. Rockchip will market the chip to its Chinese customers, Intel Chief Executive Officer Brian Krzanich said on a conference call. The U.S. company is not investing in Rockchip or providing financial support, he said. Intels partnership with Rockchip, which now sells chips based on ARM Holdings Plcs rival technology, is an effort to jump-start its entry into the growing market for tablets in China, now dominated by smaller local companies including Rockchip and Allwinner Technology Co. The agreement will produce chips designed for inexpensive tablets running Google Inc.s Android operating system.
