By Selim Bilgin, Corporate Vice President, Silicon Engineering, and Pat Stemen, Vice President, Azure Cobalt Today, we’re thrilled to announce Azure Cobalt 200, our next-generation Arm-based CPU designed for cloud-native workloads. Cobalt 200 is a milestone in our continued approach to optimize every layer of the cloud stack from silicon to software. Our design goals were to deliver full compatibility for workloads using our existing Azure Cobalt CPUs, deliver up to 50% performance improvement over Cobalt 100, and integrate with the latest Microsoft security, networking and storage technologies. Like its predecessor, Cobalt 200 is optimized for common customer workloads and delivers unique capabilities for our own Microsoft cloud products. Our first production Cobalt 200 servers are now live in our datacenters, with wider rollout and customer availability coming in 2026. Azure Cobalt 200 SoC and platform Building on Cobalt 100: Leading Price-Performance Our Azure Cobalt journey began with Cobalt 100, our first custom-built processor for cloud-native workloads. Cobalt 100 VMs have been Generally Available (GA) since October of 2024 and availability has expanded rapidly to 32 Azure datacenter regions around the world. In just one year, we have been blown away with the pace that customers have adopted the new platform, and migrated their most critical workloads to Cobalt 100 for the performance, efficiency, and price-performance benefits. Cloud analytics leaders like Databricks and Snowflake are adopting Cobalt 100 to optimize their cloud footprint. The compute performance and energy-efficiency balance of Cobalt 100-based virtual machines and containers has proven ideal for large-scale data processing workloads. Microsoft’s own cloud services have also rapidly adopted Azure Cobalt for similar benefits. Microsoft Teams achieved up to 45% better performance using Cobalt 100 than their previous compute platform. This increased performance means less servers needed for the same task, for instance Microsoft Teams media processing uses 35% fewer compute cores with Cobalt 100. Designing Compute Infrastructure for Real Workloads With this solid foundation, we set out to design a worthy successor – Cobalt 200. We faced a key challenge: traditional compute benchmarks do not represent the diversity of our customer workloads. Our telemetry from the wide range of workloads running in Azure (small microservices to globally available SaaS products) did not match common hardware performance benchmarks. Existing benchmarks tend to skew toward CPU core-focused compute patterns, leaving gaps in how real-world cloud applications behave at scale when using network and storage resources. Optimizing Azure Cobalt for customer workloads requires us to expand beyond these CPU core benchmarks to truly understand and model the diversity of customer workloads in Azure. As a result, we created a portfolio of benchmarks drawn directly from the usage patterns we see in Azure, including databases, web servers, storage caches, network transactions, and data analytics. Each of our benchmark workloads includes multiple variants for performance evaluation based on the ways our customers may use the underlying database, storage, or web serving technology. In total, we built and refined over 140 individual benchmark variants as part of our internal evaluation suite. With the help of our software teams, we created a complete digital twin simulation from the silicon up: beginning with the CPU core microarchitecture, fabric, and memory IP blocks in Cobalt 200, all the way through the server design and rack topology. Then, we used AI, statistical modelling and the power of Azure to model the performance and power consumption of the 140 benchmarks against 2,800 combinations of SoC and system design parameters: core count, cache size, memory speed, server topology, SoC power, and rack configuration. This resulted in the evaluation of over 350,000 configuration candidates of the Cobalt 200 system as part of our design process. This extensive modelling and simulation helped us to quickly iterate to find the optimal design point for Cobalt 200, delivering over 50% increased performance compared to Cobalt 100, all while continuing to deliver our most power-efficient platform in Azure. Cobalt 200: Delivering Performance and Efficiency At the heart of every Cobalt 200 server is the most advanced compute silicon in Azure: the Cobalt 200 System-on-Chip (SoC). The Cobalt 200 SoC is built around the Arm Neoverse Compute Subsystems V3 (CSS V3), the latest performance-optimized core and fabric from Arm. Each Cobalt 200 SoC includes 132 active cores with 3MB of L2 cache per-core and 192MB of L3 system cache to deliver exceptional performance for customer workloads. Power efficiency is just as important as raw performance. Energy consumption represents a significant portion of the lifetime operating cost of a cloud server. One of the unique innovations in our Azure Cobalt CPUs is individual per-core Dynamic Voltage and Frequency Scaling (DVFS). In Cobalt 200 this allows each of the 132 cores to run at a different performance level, delivering optimal power consumption no matter the workload. We are also taking advantage of the latest TSMC 3nm process, further improving power efficiency. Security is top-of-mind for all of our customers and a key part of the unique innovation in Cobalt 200. We designed and built a custom memory controller for Cobalt 200, so that memory encryption is on by default with negligible performance impact. Cobalt 200 also implements Arm’s Confidential Compute Architecture (CCA), which supports hardware-based isolation of VM memory from the hypervisor and host OS. When designing Cobalt 200, our benchmark workloads and design simulations revealed an interesting trend: several universal compute patterns emerged – compression, decompression, and encryption. Over 30% of cloud workloads had significant use of one of these common operations. Optimizing for these common operations required a different approach than just cache sizing and CPU core selection. We designed custom compression and cryptography accelerators – dedicated blocks of silicon on each Cobalt 200 SoC – solely for the purpose of accelerating these operations without sacrificing CPU cycles. These accelerators help reduce workload CPU consumption and overall costs. For example, by offloading compression and encryption tasks to the Cobalt 200 accelerator, Azure SQL is able to reduce use of critical compute resources, prioritizing them for customer workloads. Leading Infrastructure Innovation with Cobalt 200 Azure Cobalt is more than just an SoC, and we are constantly optimizing and accelerating every layer in the infrastructure. The latest Azure Boost capabilities are built into the new Cobalt 200 system, which significantly improves networking and remote storage performance. Azure Boost delivers increased network bandwidth and offloads remote storage and networking tasks to custom hardware, improving overall workload performance and reducing latency. Cobalt 200 systems also embed the Azure Integrated HSM (Hardware Security Module), providing customers with top-tier cryptographic key protection within Azure’s infrastructure, ensuring sensitive data stays secure. The Azure Integrated HSM works with Azure Key Vault for simplified management of encryption keys, offering high availability and scalability as well as meeting FIPS 140-3 Level 3 compliance. An Azure Cobalt 200 server in a validation lab Looking Forward to 2026 We are excited about the innovation and advanced technology in Cobalt 200 and look forward to seeing how our customers create breakthrough products and services. We’re busy racking and stacking Cobalt 200 servers around the world and look forward to sharing more as we get closer to wider availability next year.

By Gohar Waqar, CVP of Cloud Hardware Infrastructure Engineering, Microsoft Microsoft was the first hyperscaler to deploy the NVIDIA GB300 NVL72 infrastructure at scale – with a fully integrated platform engineered to deliver unprecedented compute density in a single rack to meet the demands of agentic AI workloads. Each GB300 NVL72 rack packs 72 NVIDIA Blackwell Ultra GPUs and 36 NVIDIA Grace™ CPUs with up to ~136 kW of IT load, enabled by Microsoft’s custom liquid cooling heat exchanger unit (HXU) system. Using a systems approach to architect GB300 clusters, Azure’s new NDv6 GB300 VMs include robust infrastructure innovation across every layer of the stack, including smart rack management for fleet health, innovative cooling systems, and efficient deployment features that make scaling high-density AI clusters easier than ever. With purpose-built hardware engineered for a unified platform – from silicon to systems to software – Azure’s deployment of NVIDIA GB300 NVL72 is a clear representation of Microsoft’s commitment to raising the bar on accelerated computing, enabling training of multitrillion-parameter models and high throughput on inference workloads. Unique features of NVIDIA GB300 NVL72 system on Microsoft Azure Ultra-dense AI rack - The GB300 rack integrates 72 NVIDIA Blackwell Ultra GPUs (each with 288 GB HBM3e each) and 36 Grace CPUs, effectively delivering supercomputer-class performance in a single rack. Advanced liquid cooling - Each rack uses direct-to-chip liquid cooling. In air-cooled data centers, external liquid cooling heat exchanger unit (HXU) radiator units in each rack dissipate ~136 kW to room air. In facilities with chilled water, the rack connects directly to facility water. Smart rack management - The system is equipped with an embedded controller that monitors power, temperature, coolant flow, and leak sensors in real time. It can auto-throttle or shut down components if conditions go out-of-range and provide full telemetry for remote fleet diagnostics. Fully integrated security and offload features: Our unique design also includes the Azure Integrated Hardware Security Module (HSM) chip and Azure Boost offload accelerator for advanced I/O and security performance. Scalable datacenter deployment - GB300 arrives as an integrated rack (compute trays, NVIDIA NVLink™ fabric, cooling, and power shelves pre-installed). Deployment is streamlined – just requiring connectivity power and cooling, performance of initial checks, and the rack self-regulates its cooling and power distribution. Purpose-built architecture designed for rapid deployment and scale At its core, GB300 is built to maximize AI compute density within a standard data center footprint. It is a single-rack AI inference and training cluster with unprecedented component density. Compared to the previous generation (NVIDIA GB200 NVL72), it introduces higher-performance GPUs (from ~1.2 kW to ~1.4 kW each with more HBM3e memory), a ~50% boost in NVFP4 throughput and a revamped power/cooling design to handle ~20% greater thermal and power load. The liquid cooling system for the GPU module is enhanced with a new cold plate and improved leak detection assembly for safe, high-density operation. Innovations in our purpose-built Azure Boost accelerator for I/O offload unlock higher bandwidth, while our custom Datacenter-secure Control Module (DC-SCM) introduces a secure, modular control plane built on a hardware root of trust, backed by the Azure Integrated Hardware Security Module (HSM). Together, these advancements enable fleet-wide manageability, strengthening security and operational resilience at scale meeting the demands of hyperscale environments. Cooling systems designed for deployability and global resiliency To dissipate ~136 kW of heat per rack, GB300 relies on direct liquid cooling for all major components. To offer resiliency and wide deployability across Microsoft’s datacenter footprint, our cooling designs support both facility-water and air-cooled environments. Both approaches use a closed coolant loop inside the rack with a treated water-glycol fluid. Leak detection cables line each tray, and the base of the rack is equipped with smart management protocols to address potential leaks. Using this method, liquid cooling is highly efficient and reliable – it allows GB300 to run with warmer coolant temperatures than traditional datacenter water, improving overall power usage effectiveness (PUE). Smart management, fleet health & diagnostics Each GB300 rack is a “smart IT rack” with an embedded management controller that oversees its operation. This controller is supported by a rack control module that serves as the brain of the rack, providing comprehensive monitoring and automation for power, cooling, and health diagnostics. By delivering an integrated “single pane of glass” view for each rack’s health, the GB300 makes management at scale feasible despite the complexity. This rack self-regulates its power and thermal environment once installed, adjusting fans or pump speeds automatically, and isolates faults – reducing the manual effort to keep the cluster running optimally so customers can focus on the workloads, with confidence that the infrastructure is continuously self-monitoring and safeguarding itself. In addition to this, the rack control module monitors and moderates GPU peak power consumption and other power management scenarios. These robust design choices reflect the fleet-first mindset – maximizing uptime and easier diagnostics in large deployments. Efficient and streamlined deployment As Microsoft scales thousands of GB300 racks for increased AI supercomputing capacity, fast and repeatable deployment is critical. GB300 introduces a new era of high-density AI infrastructure, tightly integrating cutting-edge hardware (Grace CPUs, Blackwell Ultra GPUs, and NVLink connectivity) with innovations both in power delivery and liquid cooling. Crucially, it does so with an eye toward operational excellence: built-in management, health diagnostics, and deployment-friendly design mean that scaling up AI clusters with GB300 can be done rapidly and reliably. With its unprecedented compute density, intelligent self-management, and flexible cooling options, the GB300 platform enables organizations to scale rapidly with the latest AI supercomputer hardware while maintaining the reliability and serviceability expected in Azure’s promise to customers. GB300 unlocks next-level AI performance delivered in a package engineered for real-world efficiency and fleet-scale success.
