Monaka: A small chip with major strategic significance

Save energy, celebrate performance: MONAKA delivers maximum computing power per watt and secure Confidential Computing. We’ll show you how ARM fits into your IT strategy using real-world use cases.

Based on the breakout session at the Fsas Technologies Summit 2026 with Claudia Mertinger (Business Development Solution Innovation) and Sven Stollorz (Presales Consultant).

When it comes to next-generation data centers, two terms are increasingly mentioned together: energy efficiency and data trust. This is exactly where Fujitsu’s new MONAKA processor comes in an ARM-based chip that impresses not only with its technical architecture but also with its potential to sustainably transform the IT landscape.

Why MONAKA is more than just another processor

MONAKA is Fujitsu’s answer to the growing demands of AI workloads, High Performance Computing (HPC), and secure data processing in enterprise environments. The chip is based on the ARMv9 architecture and utilizes an innovative 3D chiplet design: a 2nm compute core is combined with a 5nm SRAM stack, resulting in high power density with optimized energy consumption.

The technical specifications speak for themselves:

• 144 cores per socket (up to 288 cores in a dual-socket configuration)
• Two variants: an air-cooled version with 350W TDP and a liquid-cooled high-performance variant with 500W TDP
• Memory and I/O bandwidth: 12 channels of DDR5 (>8,000 MT/s), PCIe 6.0, and CXL 3.0 for future-proof connectivity
• Vector processing: Arm SVE2 with 256-bit support for AI and HPC workloads

But raw computing power is only one side of the story. MONAKA brings something to the table that is becoming increasingly important in an era of data protection regulations and rising compliance requirements: Confidential Computing.

Confidential Computing: Secure data processing even in the cloud

Confidential Computing makes it possible to keep data encrypted even while it is being processed. With Arm CCA (Confidential Compute Architecture), MONAKA creates isolated execution environments ("Realms") where sensitive workloads are protected from unauthorized access even from the hypervisor or the cloud provider.

This opens up new possibilities for:

• Healthcare: Processing patient data in shared cloud infrastructures
• Financial Services: Secure analysis of transaction data without disclosing raw data
• AI Development: Training models with proprietary datasets in multi-tenant environments

In the breakout session, Claudia Mertinger and Sven Stollorz demonstrated how this technology is already being used in real-world scenarios today – from encrypted VMs to attested AI pipelines.

ARM in enterprise IT: Real-world use cases

The question many IT managers are asking is: Does ARM even fit into my existing infrastructure? The answer from the summit was clear: Yes – especially where efficiency and security are the top priorities.

Concrete use cases for MONAKA in enterprise IT:

1. Private Cloud & Virtualization
   Thanks to its high core density and low energy requirements, MONAKA is ideal for virtualized environments with high demands for isolation and performance.
2. AI inference at the edge
   With INT8 computing power of up to 96.2 TOPS (high-performance SKU), MONAKA can run AI models directly on-site – without having to send data to the public cloud.
3. Sustainable data centers
   Companies looking to improve their carbon footprint benefit from the high performance-per-watt ratio. MONAKA enables more computing power with the same or even reduced power consumption.

Strategic implications for your IT planning

MONAKA is not just a technical update – it is a strategic building block for the IT of the future. For decision-makers, this means

• Diversification of processor architectures: ARM as an alternative to x86 reduces vendor lock-in and increases infrastructure resilience.
• Future-proofing with Confidential Computing: Data remains protected even in shared environments—a critical factor for compliance and trust.
• Sustainability as a competitive advantage: Energy-efficient hardware is becoming increasingly important, not just for cost reasons, but also as part of ESG reporting and Green IT strategies.

Conclusion: A chip with vision

MONAKA represents a paradigm shift: moving away from pure performance maximization toward intelligent, secure, and sustainable computing power. For companies planning their IT infrastructure for the long term, ARM and specifically MONAKA is no longer a niche solution, but a strategic option with tangible benefits.

Evaluation samples are already available, with volume production scheduled for 2027. Those who set the course now can benefit early from the advantages of this new architecture.
