But the demand for energy-efficient chips is reshaping the industry. As the PC market flattens, Intel aims to capture a sizable chunk of the rapidly growing mobile market, which rose to nearly half a billion smartphones in 2011. And chip designers in ARM's camp are eyeing a US $50 billion server market, fueled by the rise of social networking and cloud computing.
The coming months will see a number of volleys exchanged across the line that has traditionally divided the high-performance and low-power chip markets. One of the first will come from a small start-up in Austin, Texas, called Calxeda (pronounced cal-ZAY-dah). The fabless firm will begin shipping chips for servers based on 32-bit ARM mobile processor designs. They'll soon be joined by AppliedMicro, in Sunnyvale, Calif., which is working on an even speedier, 64-bit ARM-based chip. At the same time, Intel will leap into the mobile game; two big companies—Lenovo and Motorola—plan to release phones based on Intel's low-power Atom processor by the end of this year. (The very first Intel-based smartphone was launched in April by the India-based firm Lava International.)
