Advanced Micro Devices gained a few tenths of a percentage point of market share from Intel in the third quarter, but those small victories are starting to add up.
AMD saw its market share rise to 15.8 percent, according to Mercury Research, up from its second-quarter share of 15.5 percent, which was up from market share of 15 percent in the first quarter. A year ago, AMD had market share of 15.1 percent. In other words, AMD has gained close to a point of market share in a year.
Intel, meanwhile, saw its market share decline to 81.9 percent. In the second quarter, Intel had a market share of 82.5 percent. A year ago, Intel had a market share of 83.3 percent--or 1.4 percentage points more than it has today.
