China’s LineShine supercomputer in Shenzhen has topped the latest TOP500 list, becoming the world’s fastest at 2.198 exaflops and ending America’s reign since 2017. Remarkably, it runs entirely on homegrown CPUs—no Nvidia, AMD, or Intel GPUs—delivering a pointed message to Washington’s chip export controls. But experts caution the win isn’t an AI crown: LineShine ranked only fourth on AI-style benchmarks, and top US hyperscaler systems don’t even enter.
