Toshiba said it would buy microprocessors from AMD, ending its exclusive ties with Intel for the supply of the brains that run computers.
Toshiba, the world's fourth-largest laptop PC maker, said on Tuesday it expects to put AMD processors in about 20 percent of the notebooks it sells in the United States and Europe.
The move follows an announcement last year by Dell, the world's second-largest PC maker that had been procuring microprocessors only from Intel for more than two decades, that it would begin using chips from AMD.
Toshiba's decision could be a message that an era in which Intel took the lion's share of microprocessor profits as the king of PC chips is over.
Toshiba plans to put AMD chips in moderate-priced standard models for individual and corporate clients, Toshiba spokeswoman Yuko Sugahara said.
The Nikkei business daily reported earlier that prices of AMD-equipped PCs are expected to sell for up to 10,000 yen ($82) less than comparable models.
Toshiba will install AMD chips in some models to be released this summer, enabling it to reduce parts-procurement costs by at least 10 percent, the paper said.
