A global slump in personal computer demand that began with Apple Inc,'s launch of the iPad four years ago has stabilized in recent months, in part due to companies replacing employees' older laptops.

Intel said in a statement on Tuesday that demand for its chips was in good shape.

"The worldwide PC supply chain appears to be healthy, with inventory levels appropriate in anticipation of the fourth quarter retail cycles," Intel said.

The recovering PC industry has helped push Intel's shares 24 percent higher in 2014, making it the top performer in the Dow Jones industrial average. Tuesday's forecast fueled some additional buying. At 5:30 p.m. in New York, shares of Intel were up 2.2 percent at $32.85, after gaining 2.1 percent during the regular Nasdaq session.

"The telling thing will be next year. Do we continue to get a healthier, more stable PC market?," said Ascendiant Capital analyst Cody Acree. "I think the enterprise refresh largely plays out by the end of 2014 and then next year the PC industry returns to modest annual declines."

Tuesday's results, the first from a major technology company this earnings season, came after Chandler, Arizona-based Microchip warned last Thursday of weak demand in China that would soon become visible across the chip industry, sparking a broad selloff in chip stocks.

Intel said its gross margins would likely slip to 64 percent in the current quarter from 65 percent in the third quarter.

Intel has made little progress expanding from the PC industry into chips for smartphones and has been spending heavily to catch up to Qualcomm.

For the third quarter, Intel said its mobile and communications group had an operating loss of $1.04 billion on revenue of $1 million, reflecting subsidies Intel has been paying to persuade tablet makers to use its chips.

Intel posted third-quarter net income of $3.32 billion, or 66 cents a share, compared with $2.95 billion, or 58 cents a share, in the year-ago quarter as demand for personal computers stabilized. Analysts on average expected EPS of 65 cents.

Third-quarter revenue was $14.6 billion, up 8 percent from the year-ago quarter, Intel said in a statement on Tuesday. Intel said it expects fourth-quarter revenue of $14.7 billion, plus or minus $500 million.

Analysts on average expected third-quarter revenue of $14.44 billion and fourth-quarter revenue of $14.48 billion, according to Thomson Reuters I/B/E/S.
