AI Demand Sparks CPU Shortages
rwang07 · x · 2026-07-15
This interview discusses how **AI demand is pushing CPUs into shortage territory**, not just GPUs. ### Core Insights - **CPUs are in short supply**: Surging demand has led to them being "completely sold out." - **Why massive CPU power is needed**: - CPUs are critical in **Reinforcement Learning**. - Complex training environments run on CPUs rather than GPUs or ASICs. - For instance, when models operate in complex physics simulations or CAD editing environments, the underlying execution relies heavily on CPUs. - **Post-deployment demand continues to grow**: Once models generate code and useful outputs, this further drives up compute and system-side resource consumption. - **Broader supply-demand context**: The interview also touches on surging AI expenditures, Token supply and demand, Anthropic's compute issues, potential shortages triggered by TSMC's massive capital expenditures, and **robots as the next major wave of demand**.
