A practical guide to choosing the right datacenter CPU for agentic AI workloads. This article introduces a reasoning-versus-action framework that maps nine hardware metrics across 17 server CPUs from NVIDIA, AMD, Intel, AWS, Google, Microsoft, ARM, Ampere, and Huawei. Whether your workload is GPU-heavy deep reasoning or CPU-heavy multi-agent orchestration, the scoring methodology helps you match the right silicon to the right job — and understand why no single chip does both well.
