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.
