A spike in the number of processors shipped helped Intel record an increase in its third-quarter revenue and income.

The chip-maker reported third-quarter revenue of $10.1bn, a 15 percent increase year-on-year. The company also recorded net income of $1.9bn, a 43 percent increase year-on-year.

The results were helped by a healthy global demand for processors and chipsets, which strengthened as the quarter progressed, Intel CEO Otellini said. The number of Intel chipsets shipped went up with mobility and vPro, a hardware and software platform to manage business PCs, Otellini said.

"Notebooks as a generic product type is igniting in markets around the world," Otellini said, adding that Santa Rosa and Centrino were getting wide acceptance as mobile platforms.

Intel shipped more than 2 million quad-core processors during the quarter, the company said.

A number of big announcements came during the quarter, which ended on 29 September. At the Intel Developer Forum in September, the company announced it will ramp up performance and energy efficiency in its microprocessors by using a 32-nanometre process technology starting in 2009, with the Nehalem processors.

It also announced the next generation of vPro processor technology during the quarter.

The strong quarter is also a sign that Intel's restructuring efforts are succeeding, said Paul Otellini, president and CEO of Intel. The company saw better operational efficiency by cutting costs and reducing the headcount by 12 percent from last year's total.

This not an end of the strategy, but part of larger recovery strategy, said Andy Bryant, Intel's newly minted chief administrative officer. The company is in line to record $2bn in savings and operational efficiency in 2007, Bryant said.

The company's headcount currently stands at 88,000 and is expected to fall to 86,000 by the end of the year, he said.
