Market Share Overview

In the fourth quarter of 2012 the overall PC processor market declined six percent compared to the third quarter. This is worse than the season average of the previous five years, which is a 1.1 percent decline for this quarter. On-year growth was down 11.4 percent, exceeding the on-year decline seen during the fourth-quarter market collapse of 2008 (8.8 percent). This quarter’s results are now also the second-worst on-year decline in the past 20 years, exceeded only by the first quarter of 2001, and displacing the prior quarter for the dubious honor.

Intel gained share in all segments this quarter, with mobile gaining two full points of share. AMD lost share in all segments.

Only server CPUs grew this quarter – up 2.4 percent and again due solely to Intel. The mobile segment was down 8.9 percent in the fourth quarter, while desktop CPUs were down 7.0 percent.

For all of 2012, Intel’s market share was 82.5 percent, up two points from 2011. AMD’s share declined 1.9 points to 16.9 percent, while VIA’s share was unchanged at 0.5 percent.

If ARM-based computing devices were included in the annual share computations, collectively they would hold 24.6 percent of the market, up from 12.6 percent in 2011.
