Overview
Microsoft just put Azure Cobalt 200 Arm VMs into early access preview at Build 2026. Up to 50% better generational performance over Cobalt 100, purpose-built from silicon to networking for scale-out cloud-native AGENTIC AI workloads. Already in 10+ global regions. This is Microsoft going head-to-head with AWS Graviton 4/5 on the workload that matters most for the next 5 years.
✅ What Cobalt 200 actually is at the silicon level
✅ Why agentic AI is a different compute profile (fan-out, stateful, latency-bound)
✅ Cobalt 200 vs AWS Graviton 4 / Graviton 5
✅ Why Arm + co-designed system is the cost-per-inference moat
✅ Honest trade-offs (preview, x86 migration, workload specificity, lock-in)
✅ 3 moves this week for Azure / multi-cloud teams
