AMD and KDDI Collaborate on Advancing 5G Virtualized Network in Japan

—   KDDI adopts AMD EPYC CPUs to advance data centers in the era of AI —

SANTA CLARA, Calif. — Apr. 23, 2025 — AMD (NASDAQ: AMD) and KDDI Corporation, under the new leadership of CEO Hiromichi Matsuda, today announced an agreement to leverage 4^th Gen AMD EPYC™ CPUs for KDDI’s advanced 5G virtualized network. The adoption of AMD EPYC CPUs will enable KDDI to deliver impressive performance and highly efficient traffic processing capability for 5G virtualized network. Validation efforts will begin in 2025 and are planned to be rolled out to commercial networks in Japan in 2026.

Additionally, KDDI and AMD will undergo validation and testing efforts to further enhance KDDI 5G core networks. As technology partners, the two companies aim to contribute to the improvement of the KDDI customer experience and the development of energy efficient solutions to power 5G network and next-gen communication infrastructure in the era of AI.

“We are excited to expand our work with KDDI and President Matsuda to accelerate the transformation of Japan’s 5G infrastructure,” said Dr. Lisa Su, chair and CEO, AMD. “The leadership performance and energy efficiency of our 4^th Gen AMD EPYC processors will help scale KDDI’s network capabilities to deliver faster and more energy efficient network infrastructure that is required to power the next generation of virtualized networks and AI-enabled data centers.”

“We are very excited to work with AMD to realize the higher performance and lower power consumption of 5G virtualized networks,” said Hiromichi Matsuda, president and CEO, KDDI. “By leveraging AMD's world-leading semiconductor development capabilities, we expect to dramatically improve KDDI's network capabilities. Furthermore, through this collaboration, we expect that AMD's cutting-edge technologies can be deployed in our data centers in the era of AI, and we are confident that we will be able to accelerate the progress of technological innovation together and evolve ‘the power to connect.’”
