The U.S. Federal Trade Commission (FTC) is preparing an investigation of Intel's business practices as part of a possible antitrust investigation. The FTC has subpoenaed both Intel and AMD as part of its investigation according to sources at both companies. Intel has stated it is cooperating with the FTC in the matter. This has got to be good news to AMD which is embroiled in a legal battle with Intel over what AMD see as unfair business practices. The announcement comes on the heels a a recent decision by South Korea where Intel was fined $25.5 for allegedly abusing its dominant market position. Intel is already facing a similar investigation by the European Commission regarding rebates and discounts offered to OEMs in an effort to freeze AMD out of the market.
