Mercury Research figures released by AMD show that the chipmaker saw its market share rise from 7.4 percent in the first quarter to 11.2 percent in the second quarter, a 51 percent jump. Revenue generated by Opteron rose 89 percent from the first quarter to the second, according to AMD.

The market share figure, which will likely be disputed by Intel and possibly contradicted by other market share surveys, represents the first time AMD has crossed into double-digit territory in server chips. Two and a half years ago, before Opteron, AMD had only a nominal presence in this market.
