TOKYO, JAPAN -- 5/23/2001 -- AMD today announced that NEC, Sony Corporation and Fujitsu, three of Japan's largest computer manufacturers, are expected to feature notebook PCs based on seventh-generation mobile AMD Athlon™ 4 and mobile AMD Duron™ processors.

Collectively, these companies commanded over 50 percent of total PC shipments, including notebooks and desktops, for the year 2000 in Japan. Japan is the world's second largest consumer of PCs. NEC, the country's leading PC maker, is the first to adopt the newly introduced 1GHz mobile AMD Athlon™ 4 processor in Japan.

The mobile AMD Athlon 4 processor is the world's highest performance processor for the notebook PC market and features the innovative AMD PowerNow!™ technology, which can extend system battery life up to 30% without compromising performance and offers up to 50 percent more performance than competitive systems running on batteries.

Sony and Fujitsu have both announced systems based on the mobile AMD Duron processor. NEC is also offering systems based on the mobile AMD Duron processor.

"We are very pleased these prestigious companies have chosen the mobile AMD Athlon 4 and mobile AMD Duron processors," said Kazuo Sakai, president, AMD Japan. "With notebook PCs comprising approximately 50 percent of the PC market in Japan, these key notebook systems establish AMD in both performance and value mobile computing."

The mobile AMD Athlon 4 and mobile AMD Duron processors support AMD's Socket A platform architecture, providing stability and reliability. The Socket A platform provides a cost-effective migration path to the latest technology for both business and consumer users.

NEC plans to use the 1GHz mobile AMD Athlon 4 processor in its "LaVie G" series. An 800MHz mobile AMD Duron processor will also be featured in the "LaVie G" series, as well as the "LaVie L" series. These consumer systems are expected to ship later this month.

Sony is announcing a "VAIO note" system for the Japanese consumer market that features a 700MHz mobile AMD Duron processor. Sony plans to ship these systems later this month. Sony currently offers a VAIO FX210 notebook PC that incorporates the mobile AMD Duron processor in the U.S. retail channel.

Fujitsu is introducing a consumer notebook PC using an 800MHz mobile AMD Duron processor in its "FMV-BIBLO" series notebook in Japan. These consumer systems are expected to ship later this month.
