Trying to ban AI-capable CPU exports to China would be like trying to ban oil. That’s the analogy Arm Holdings CEO Rene Haas offered during Computex 2026 in Taipei, arguing that the widespread, general-purpose nature of CPUs makes any meaningful export restriction a logistical and technical nightmare.
Haas described such a ban as “nearly impossible,” pointing to the fundamental challenge of defining performance thresholds for chips that power everything from smartphones to data centers to industrial equipment. Unlike GPUs, which have relatively narrow, well-defined use cases, CPUs are embedded in virtually every computing device on Earth.
Why CPUs aren’t GPUs
When the US government restricted Nvidia’s high-end GPU exports to China, regulators could draw reasonably clear lines. GPUs have specific compute benchmarks that make it possible to say “this chip is too powerful for export” without accidentally banning your cousin’s gaming rig.
CPUs don’t work that way. Haas argued that restricting CPU exports would require what he called a “pretty hardcore cut,” essentially a comprehensive ban that would ripple through global supply chains in ways GPU restrictions never did.
