WASHINGTON — The Federal Trade Commission has opened a formal antitrust investigation of Intel, the world’s largest maker of computer microprocessors, for anticompetitive conduct, government officials and lawyers involved in the proceeding said Friday.

The officials and lawyers said that in recent days Intel, its smaller rival Advanced Micro Devices, and several of the world’s largest personal computer makers that buy semiconductors from the two companies have begun to receive subpoenas from the commission.

The investigation into accusations that Intel’s pricing policies in the United States and abroad have been designed to maintain a near-monopoly on the microprocessor market was authorized by William E. Kovacic, the new chairman of the trade commission, and has the support of the agency’s other commissioners.

It reversed a decision by his predecessor, Deborah P. Majoras, who had been blocking the formal inquiry for many months, frustrating other senior commission officials and some lawmakers on Capitol Hill.

Ms. Majoras is a former senior official in the antitrust division at the Justice Department who was an architect of the Bush administration’s antitrust settlement with Microsoft in 2001. She stepped down two months ago to become the general counsel at Procter and Gamble.

There was no immediate comment from Intel or A.M.D. about the Federal Trade Commission’s decision.

Since it will almost certainly be many months before the commission decides whether to make a case against Intel, as European and Asian regulators already have, the investigation could mark an important early test for the next administration on antitrust and competition policy.
