Worldwide computer microprocessor unit shipments and revenues in the second calendar quarter of 2010 (2Q10) increased 3.6% and 6.2%, respectively, compared to the first quarter of 2010, according to the latest PC processor study from International Data Corporation (IDC).

The average sequential change in unit shipments between a calendar year's first quarter and its second quarter is an increase of 1.6%. For revenues, the average sequential change is a decrease of -2.8%. So, these increases represent better performance than usual for a second calendar quarter.

"Such a sequential increase in PC processor shipments alone would have been enough to conclude that the first half was strong for the market," said Shane Rau director of Semiconductors: Personal Computing research at IDC (http://www.idc.com). "However, a modest rise in revenues, too, points directly to a rise in average selling prices. System makers bought more and higher-priced computer processors in 2Q10 than in 1Q10. Digging a little deeper into the numbers shows that they bought more mobile processors and more server processors, while desktop processors remained flat."

Looking at market performance by form factor, mobile computer processor unit shipments rose 6.5% quarter over quarter, computer server processors rose 6.1% quarter over quarter, and desktop computer processors declined -0.1% quarter over quarter.
2Q10 Vendor Highlights

For the overall worldwide computer microprocessor market in 2Q10, Intel earned 80.7% unit market share, a loss of 0.3%, while AMD earned 19.0%, a gain of 0.2%, and VIA Technologies earned 0.3%.

In 2Q10 unit share by form factor, Intel earned 86.1% share in the mobile computer processor segment, a loss of -1.7%. AMD finished the quarter with 13.7%, a gain of 1.6%, and VIA earned 0.2%. In the server/workstation processor segment, Intel finished with 93.5% market share, a gain of 3.3% and AMD earned 6.5%, a loss of 3.3%. In the desktop processor segment, Intel earned 72.2%, a gain of 0.5%, AMD earned 27.3%, a loss of -0.7%, and VIA earned 0.5%.
Market Outlook

IDC's forecast for worldwide processor unit growth in 2010 is 19.8%. However, market demand for processors weakened during the second quarter and is expected to remain weak in August.
