As AI shifts from training to inference and agentic workloads, Server CPU evolves from auxiliary to core orchestrator, lifting both ARM and x86 demand into a new growth cycle.

Key Highlights

Demand Shift: AI moves from training to inference and agentic deployment, elevating CPU's role as the system orchestrator with strong shipment growth projected for 2026.
Agentic AI Driver: Agent architectures demand CPU-intensive orchestration; CPU-to-GPU ratios are rising from 1:8 toward 1:1 in inference clusters.
ARM Expansion: CSP custom CPUs and NVIDIA's Grace/Vera AI Rack solutions jointly push ARM server CPU share past 20% for the first time.
x86 Resilience: Intel Xeon and AMD EPYC continue to benefit from AI infrastructure buildout, with AMD posting particularly strong shipment growth alongside the broader market upturn.
