It would be tempting to say that Intel's year-over-year loss was Sunnyvale, Calif.-based AMD's gain. But the smaller x86 chip maker's 2.2 percent market share increase -- from 10.9 percent of global microprocessor revenue in Q1 2007 to 13.0 percent in Q1 2008 -- had twice as much to do with the shrinking share of other vendors besides the big two. Microprocessor makers not named Intel or AMD lost nearly a point-and-a-half in global market share year-on-year, dropping from 8.7 percent of revenues in 2007's first quarter to 7.3 percent in the first quarter of 2008.
