The embattled chipmaker A.M.D. now has some Middle Eastern money to help it in its fight against rival Intel.

The Mubadala Development Company, which is the investment vehicle of the government of Abu Dhabi in the United Arab Emirates, has invested $622 million for an 8.1 percent stake in the chipmaker A.M.D. The news was first reported by the Financial Times.

"This investment strengthens A.M.D.'s ability to deliver customer-centric innovation and choice to the marketplace, creating greater value for all of our shareholders," said A.M.D. chief executive Hector Ruiz in a statement.

Mubadala paid $12.70 per share for its stake, which was A.M.D.'s closing price yesterday. Its share price was unchanged in morning trading.

The Abu Dhabi investment firm will not receive a board seat, and its investment is considered noncontrolling.

A.M.D., which is a distant second behind semiconductor giant Intel, has waged a David versus Goliath battle in recent years. A.M.D. gained ground when it beat Intel to market with improved technology several years ago, but it fell behind in recent quarters after Intel slashed its prices. In the third quarter, A.M.D. lost $396 million, and it is expected to remain in the red for the coming quarters.
