CPUs Were the 'Dead' Layer — The Data Now Says They're the Scarcity in AI Infrastructure

As AI data-center spending shifts from GPU-heavy training to CPU-driven inference and agentic workloads, the general-purpose CPU has become the scarce orchestrator. Server CPU lead times have stretched past 16 weeks, with Intel and AMD reporting record server CPU sales. Intel's data-center and AI group hit $6.3 billion in Q2 2026, up 59% year-over-year, while AMD's data-center revenue more than doubled to $6.72 billion.
