KDDI and AMD agreed on technology collaboration toward advancing 5G Virtualized Network
―Adopts AMD EPYC CPU and advance data centers in the era of AI―
KDDI CORPORATION
On 23rd April 2025, KDDI Corporation (Headquarters: Chiyoda-ku Tokyo, Japan, President & CEO Hiromichi Matsuda) and AMD (Headquarters: California, U.S.A., CEO: Dr. Lisa Su) agreed to leverage 4th Gen AMD EPYC™ CPU for KDDI's 5G virtualized network and collaborate on technology toward advancing 5G virtualized network in the era of AI.
Validation efforts will begin in 2025 and are planned to be rolled out to commercial networks in Japan in 2026.
AMD EPYC™ CPUs use state-of-the-art chiplet technology to integrate multiple small chips into a single processor, with more cores than traditional one-piece designs, achieving both high performance and low power consumption.
The adoption of AMD EPYC CPUs will enable KDDI to deliver impressive performance and highly efficient traffic processing capability for 5G virtualized network.
Additionally, KDDI and AMD will undergo validation and testing efforts to further advance CPU usage through the use of AMD EPYC CPUs in 5G virtualized network. Based on the validation results, KDDI and AMD will explore the possibility of upgrading CPU usage and utilizing them in data centers in the AI era.
■Background
- In the future, 5G communication traffic is expected to increase due to the expansion of the use of AI, and there is a need to improve the performance and ensure the stability of 5G networks.
- In addition, as communication traffic increases, the power consumption of servers and network equipment that process communication will also increase. Optimizing the energy efficiency of telecommunications networks is critical to supporting the sustainable delivery of telecommunications services.
- KDDI is promoting the virtualization of its 5G core network, and it is possible to flexibly introduce optimal hardware to achieve high performance and power saving without relying on specific hardware.
■Endorsement
"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.'"
"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 4th 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."
As technology partners, the two companies aims 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.
