Achieving world-class AI inference performance through Japan-developed 2nm 3D-stacked CPU and server integrated, developed, and manufactured in Japan

KAWASAKI, Japan, Sept. 14, 2026 /PRNewswire/ -- Fujitsu Limited today announced that it will begin global sales of its next-generation CPU, FUJITSU-MONAKA^[1], designed and developed in Japan, starting November 2026. This will include sales of the processor as a standalone product to cloud and data center operators and server vendors. Additionally, the company will launch the made-in-Japan Fujitsu MONAKA Server equipped with the FUJITSU-MONAKA CPU, offering high reliability and power efficiency as a sovereign AI infrastructure. Fujitsu MONAKA Server will be made broadly available from November 2026 to data center operators, enterprises, and the academic and HPC sectors in Japan and Europe, contributing to national security.

The FUJITSU-MONAKA CPU integrates Fujitsu's extensive expertise in processor and server development, achieving world-class computational performance and data supply capabilities with a maximum operating frequency of 3.8GHz and memory transfer speed of 8800MT/s. It delivers twice the AI inference throughput and superior power efficiency compared to other CPUs, effectively halving the number of servers and power consumption required for equivalent processing loads.

Fujitsu MONAKA Server, powered by the FUJITSU-MONAKA CPU, enhances sovereign capabilities through domestic manufacturing, contributing to traceability and supply chain transparency. Furthermore, at a time when power and installation space are significant challenges for AI infrastructure expansion, this CPU server alone can build an AI inference platform. Its space-saving and power-efficient design allows for deployment in air-cooled data centers, significantly increasing customers' capacity for AI infrastructure expansion. Fujitsu MONAKA Server also supports future scalability through resource pooling technology and reduces cooling energy consumption with Fujitsu's long-cultivated cooling technologies.

Fujitsu is committed to supporting customers' autonomy and accountability by providing a sustainable sovereign AI infrastructure with high operability.
