Fujitsu has shared new details on its upcoming Arm-based Monaka processors during its Technology Update 2025 event. Monaka is planned as the company's next major datacenter CPU line, with the first chips arriving in 2027 on a 2 nm process. The initial Fujitsu Monaka CPU uses the Armv9-A architecture and a 3D chiplet layout combining a core die with separate SRAM and I/O dies. A single chip carries 144 cores, with two-socket configurations scaling to 288 cores per node. The platform supports 12-channel DDR5, PCIe 6.0 with CXL 3.0, and Arm SVE2 for AI and HPC workloads. Fujitsu is positioning it as a high-efficiency part aimed at AI inference, simulation, and large-scale data processing.

From there, the roadmap moves into more specialized designs. Targeted for late 2029, Monaka-X is a CPU-only built on a 1.4 nm class process. Fujitsu says it will be the first server CPU to implement Arm SME (Scalable Matrix Extension). The chip uses a 3D many-core layout tightly coupled with a GPU and includes hardware confidential-computing features as standard. The next CPU will be Monaka-X with NPU planned for the second half of 2030. This variant adds an on-package NPU aimed at mid-sized LLMs. Fujitsu is exploring a reconfigurable engine plus a dedicated quantization accelerator. Arriving in 2031, Monaka-XX is described as a full CPU-NPU fusion chip, again planned to be built on 1.4 nm or newer nodes. Overall, the roadmap shows Fujitsu pushing deeper into high-core-count Arm servers with increasing AI acceleration built directly into the platform.
