The CPU Returns to the Core: Intel, AMD, and ARM's Architectural Bets for the Agentic AI Era
March 2026 saw NVIDIA Vera CPU and ARM AGI CPU launch in the same month, marking the end of the GPU-only era. Agent workloads have CPU accounting for 50-90% of latency; Morgan Stanley projects the CPU market reaching $82.5-110B by 2030. Intel allies with NVIDIA for NVLink Xeon; AMD bets on open ecosystem (UALink+ROCm 7); ARM self-develops AGI CPU with 136 cores delivering 2x x86 density. Three companies, three philosophies: compatibility, openness, energy efficiency density. 2027-2028 will be pivotal.
