又一颗2纳米Arm芯片，144核

Core Viewpoint - Fujitsu has unveiled its MONAKA processor, which is set to be released in the fiscal year 2027, during the MWC event alongside its spinoff network equipment supplier 1FINITY [2] Group 1: Processor Specifications - The MONAKA processor is the successor to the Arm A64FX processor, which was utilized in the Fugaku supercomputer. The A64FX was manufactured using a 7nm process, while MONAKA's CPU cores will be produced using a 2nm process [4] - MONAKA features a 3D chip structure, with cache and I/O chips both manufactured using a 5nm process, arranged in a combination of 2D and 3D stacking [4][14] - The CPU core utilizes the Armv9-A architecture (compatible with SVE2), supports dual sockets with 144 cores per socket, and is equipped with 12 channels of DDR5 memory, along with support for confidential computing [11] Group 2: Future Developments and Market Demand - Fujitsu has previously announced support for NVIDIA and NVLink Fusion, but the current release does not mention NVLink Fusion, indicating that the first version of MONAKA may not support it, with future versions potentially including this feature [11] - There is a growing demand for domestically produced IT products that do not rely on foreign supply chains or data storage locations, referred to as "sovereign demand." This trend is becoming increasingly significant in the data center industry, making MONAKA's development crucial for Japanese manufacturers [11] - Fujitsu showcased an engineering sample of MONAKA, which includes a package of chips and components, as well as a wafer that stacks SDRAM and CPU chips in a 3D configuration [12]
