Intel has long been the leader in desktop and laptop processors, but the company hasnt made much headway in the smartphone market as only a handful of handsets, none of which currently ship in America, carry its current-gen Atom Z2420 Medfield processor. However, the companys mobile fortunes could be about to change as it unveiled a pair of new high-speed, low power 64-bit mobile processor platforms here at Mobile World Congress. With its next-generation Atom Z3400 Merrifield dual-core processor and Atom Z3500 Moorefield quad-core chip, the company is hoping grab market share from Qualcomm and other ARM-based CPU vendors.
