Chinese supercomputer powered by homegrown chips tops US models in global ranking

A Chinese supercomputer named LineShine has ascended to the top of the global TOP500 ranking, marking the first time since 2017 that a China-based machine has claimed the most powerful computing system title. Housed at the National Supercomputing Center in Shenzhen, LineShine surpassed the United States' El Capitan, which previously held the leading position, in the latest semi-annual list announced at the ISC 2026 conference in Hamburg, Germany.

This significant achievement highlights China's advancements in indigenous technology, as LineShine operates entirely on domestically developed LX2 processors, leveraging a custom LingKun platform, LingQi interconnect, and the Kylin operating system, without reliance on foreign graphics processing units (GPUs). The system recorded a debut performance of 2.198 exaflops on the High Performance Linpack (HPL) benchmark, demonstrating China's capability in high-performance computing amidst ongoing technological competition and export controls.
