Both AMD and Intel grew microprocessor market share in fourth quarter of 2007, according to new figures released by iSuppli Corp. AMD in the fourth quarter grew its share by 0.3 percentage points compared to the third quarter of 2007, while Intel increased its revenue by 0.2 percentage points sequentially. 

However, only Intel grew its share when comparing the fourth quarter 2007 results to the same period in 2006, with a 3.1 percent increase. AMD lost 1.5 percent of market share.

“With strong PC demand in the fourth quarter, particularly in the notebook segment, microprocessor Average Selling Prices (ASPs) for both AMD and Intel held firm,” said Matthew Wilkins, Principal Analyst for Compute Platforms Research at iSuppli.
“Global unit shipments of PCs in the fourth quarter rose by 14.2 percent compared to the same period in 2006. This strong demand, along with increased sales of higher-end microprocessors, helped to sustain ASPs.”

Combined, AMD and Intel accounted for 93 percent of overall microprocessor revenues in the fourth quarter of 2007, up 1.6 percentage points from the fourth quarter of 2006. On an annual basis the two accounted for just over 92 percent of market revenue in 2007, a gain of 1.4 percentage points from 2006.
