Alibaba, Biren, and other Chinese design houses have spent years and millions of dollars creating the blueprints for advanced processors to power the country’s next generation of supercomputers, artificial intelligence algorithms and data centers.Both Alibaba and Biren had already conducted expensive test runs of their latest chips at TSMC when Washington unveiled the controls.Its shares have lost 80 percent of their value since Beijing canceled sister group Ant’s initial public offering two years ago.“Attempting to freeze a country in place for a technological level of hardware is a big deal,” said Paul Triolo, head of tech policy at consulting group ASG.“That is what the US is trying to do by restricting sales and closing off the manufacturing road map to get to these advanced levels of hardware.”Triolo said high-end processors were the building blocks for research into supercomputing and AI, which power everything from autonomous driving to drug discovery."
