Intel may still be king of the microprocessing hill, but from the looks of IDC’s latest market report, scrappy underdog AMD is starting to claim more of the $9.5 billion dollar pie. The semiconductor stalwarts faced off in four separate market categories with runner-up AMD seeing gains in all, save for servers where its paltry 5.5 percent share dropped 0.6 percent versus Intel’s commanding 94.5 percent lead. The Q2 2011 report pegged Intel’s overall worldwide share at 79.3 percent, a 1.5 percent decrease from the previous quarter, while AMD saw a 1.5 percent increase to 20.4 percent. For the mobile PC realm, Intel once again saw a decline as its 84.4 percent share took a 1.9 percent quarter to quarter tumble, with AMD again seeing a nearly 2 percent gain in its 15.2 percent stake. In the desktop PC segment, AMD grabbed an additional 1.5 percent, bringing its stake to 28.9 percent, with Intel’s 70.9 percent share dropping 1.5 percent versus Q1 2011. Wondering where the second place chip maker got its second quarter stride? According to the research firm, its new Fusion platform, along with Intel’s, now accounts for “more than 60% of total PC processor unit volume in 2Q11.” You paying attention, Sandy? It’s time to sleep with one eye open.
