AMD now accounts for 21.4 percent of all desktop, notebook and server processors using the x86 instruction set that were shipped during the fourth quarter. The chipmaker’s share grew from 17.7 percent in the third quarter, on strong gains in all three of those segments. Surging shipments of Opteron server processors have been one of the strongest reasons for AMD’s success during 2005. The server market was almost completely absent from the company’s strategy the last time they reached 20 percent market share, in 2001. AMD’s share of the x86 processors shipped into the server market grew from 12.7 percent to 16.4 percent from the third quarter to the fourth. The company’s growth in the desktop and mobile markets was just as strong in the second half of 2005. AMD’s desktop processor share went from 20.4 percent in the third quarter to 24.3 in the fourth, and its mobile share went from 12.2 percent to 15.1 percent.
