Is Hector Ruiz launching AMD into the business of making PCs? Not exactly. But after getting pummeled by Intel in 2007, the chipmaker wants to have more of a hand in designing them. It's no longer enough to sell chips, a field in which AMD excels technically; one must sell "chipsets" — entire ready-to-go packages of computing parts, including all the silicon a computer needs. Dell, HP, and others will actually manufacture AMD's new "Business Class" desktops and notebooks.
