EL SEGUNDO, CA – Third-quarter global PC shipments were up 7% sequentially and 10.3% year-over-year to 88.1 million units, according to iSuppli Corp.

Shipments for all three major types of PCs – desktops, notebooks and entry-level servers – rose on both a sequential and a year-over-year basis in the third quarter.

Desktop PCs generated the strongest sequential growth, with shipments up 11% sequentially, reflecting relatively strong demand in the corporate sector.

In contrast, mobile PC shipments rose at more tepid 4% sequential growth rate, and up a more impressive 15% from a year earlier. Those rates, however, were down from 41% and 42% increases in the second and first quarters, respectively, due to consumer confidence issues, says the firm.

iSuppli predicts global PC shipments will continue to rise in the fourth quarter, with a mid-single-digit increase over fourth-quarter 2009 shipments.
