eWeek reports that analyst firm In-Stat expects the mobile processor market to see heightened competition in the second half of 2009, as x86 chip makers such as Intel and AMD continue to drive down power consumption and ARM vendors, including Freescale, Texas Instruments and Samsung, grow the performance of their processors by adding more cores. In-Stat also expects to see the mobile processor market grow by 22.3 percent by 2013.
