Core Viewpoint - Fujitsu is transitioning its focus from high-performance computing to scalable traditional data center infrastructure with its next-generation processor, Monaka, which is designed for cloud-native workloads and aims for efficient, secure computing [1][2][37]. Group 1: Monaka Processor Overview - Monaka is built on a 2nm core chip with a 3D multi-core layout, optimized for air-cooled servers and conventional memory, targeting confidential computing and low-voltage operation [1][3][6]. - The processor will feature 144 Armv9-A cores per slot in a dual-slot configuration, totaling 288 cores, and is designed for standard 2U data center servers [3][6]. - Monaka aims to achieve generational improvements in application performance and performance per watt, with a projected launch in fiscal year 2027 [10][38]. Group 2: Design and Efficiency - The design incorporates advanced silicon for critical areas while using more cost-effective processes for larger SRAM and IO chips, aligning with Japan's energy efficiency goals [6][10]. - Monaka will utilize DDR5 and PCIe Gen6 for high throughput IO, avoiding special packaging or HBM to enhance memory bandwidth [6][10]. - The chip is expected to have a power consumption of less than 500W, suitable for standard server racks, focusing on scalability and efficient throughput rather than peak floating-point performance [6][10]. Group 3: Security and Reliability - Monaka emphasizes trust with hardware-level isolation, workload protection, and system resilience, positioning it as a confidential computing platform for multi-tenant environments [19][22]. - It features full memory encryption and a hardware root of trust to enhance system-level security and verify firmware authenticity [22][19]. - Reliability features include error detection and correction mechanisms, thermal control, and maintainability, aiming for high uptime in large-scale distributed deployments [22][19]. Group 4: Software and Ecosystem - Monaka is designed to run standard Linux stacks, supporting upstream distributions and common development tools, ensuring compatibility and accessibility for developers [24][27]. - The development stack will support LLVM, GCC, and Python, maintaining consistency with tools used in previous Fujitsu architectures [27][24]. - Monaka will support CXL 3.0 for composable infrastructure and PCIe Gen6 for compatibility with next-generation storage and networking devices [30][24]. Group 5: Market Positioning - Fujitsu positions Monaka as a "mainframe-class" processor, focusing on predictable behavior, lifecycle control, and secure leasing, rather than just throughput aggregation [31][34]. - The processor targets markets that require platform integrity, such as sovereign cloud deployments, telecommunications, and defense sectors, emphasizing reliability over raw performance [34][31]. - Monaka represents a continuation of Fujitsu's decades-long experience in processor design, transitioning from SPARC to Arm architecture while prioritizing control and integration [35][37].
