Microsoft Azure Cobalt 200 ARM Chip: AI-Powered, 50% Performance Boost
Microsoft Announces Cobalt 200: Next-Gen Azure ARM Processor
At the recent Microsoft Ignite conference, the company introduced the Cobalt 200 — the successor to the Azure Cobalt 100 ARM processors.
Key highlights:
- 50% performance increase over Cobalt 100
- Integrated latest Microsoft security, networking, and storage technologies
---
Adoption and Benchmark-Driven Design
Since the GA release of Cobalt 100 VMs, major players such as Databricks and Snowflake have been running production workloads on these processors.
For Cobalt 200, Microsoft designed the system using:
- Customer-informed benchmarks covering:
- Databases
- Web servers
- Storage caches
- Network transactions
- Data analytics
---
Data-Driven Engineering Process
Microsoft’s development approach featured:
- Digital twin simulation — modeling servers from silicon upwards, including CPU microarchitecture and full server design.
- AI-powered performance simulation — leveraging Azure’s compute to evaluate:
- 140 benchmarks
- Across 2,800 hardware parameter combinations (core counts, cache sizes, memory speeds, rack configurations)
- Large-scale configuration testing — over 350,000 system variations evaluated
> “This extensive modeling and simulation allowed us to identify the optimal design point for Cobalt 200, delivering >50% higher performance than Cobalt 100 while maintaining Azure’s most power‑efficient platform.”

Why Neoverse V3 Matters
The move from Neoverse N2 to V3 offers:
- Higher instructions-per-cycle (IPC) efficiency
- Edge over competitors using older architectures, such as:
- Amazon Graviton 4 – V2
- NVIDIA Grace – V2
- Cobalt 100 – N2
Cobalt 200’s 132 cores outnumber:
- Graviton 4 – 96 cores
- NVIDIA Grace – 72 cores
This signals a multi-generational leap in compute density and efficiency.
