Intel has reported a 44-percent increase in second-quarter profit, to $1.3bn. Lower selling prices for its processors during the period were offset by higher than expected unit shipments, Intel said.

Asia-Pacific, excluding Japan, accounted for 51 percent of Intel's $8.7bn second-quarter sales, largely because so many of the world's computers are manufactured in the region, the company said. That figure does not reflect where those computers are bought by end users.

When looked at from a consumption basis, processor shipments to end users in the three main regions - the Americas; Europe, the Middle East and Africa; and Asia - are roughly equal, with each accounting for about one-third of unit shipments, said John Antone, vice president and general manager of Intel Asia-Pacific.
