LineShine returns China to the top: 2.198 exaflops/s — world's most powerful supercomputer outruns El Capitan and breaks the two exaflop barrier
After nearly a decade, China is again the leader of the TOP500 ranking. The system in Shenzhen achieved sustained performance of 2.198 exaflops/s, ahead of the US El Capitan (1.809). The Hamburg conference drew 3,400 participants and 188 exhibitors, including Huawei, Lenovo and Sugon.
As reported by CCTV+, the Chinese supercomputer LineShine has been officially recognised as the world's most powerful supercomputer in the global TOP500 list, marking China's return to the world stage of supercomputing after nearly a decade. The ranking was announced on Tuesday at the International Supercomputing Conference (ISC) High Performance 2026 in Hamburg, Germany, a major European conference and exhibition for the high performance computing community.
Located at the National Supercomputing Centre in the southern Chinese tech hub of Shenzhen, LineShine overtook the US based El Capitan system to become the world's most powerful supercomputer according to the High Performance Linpack (HPL) benchmark. LineShine achieved 2.198 exaflops/s on HPL, becoming the first system in TOP500 history to exceed two exaflops of sustained double precision performance, while El Capitan dropped to second place with 1.809 exaflops/s. The recognition of LineShine as the world's fastest supercomputer comes after China's Sunway TaihuLight held the title in 2017.
The conference, held from Monday to Friday, brought together more than 3,400 participants, including scientists, engineers, technology providers, infrastructure specialists and policymakers, to discuss the latest advances in AI, quantum technology and supercomputing. The ISC 2026 exhibition featured 188 exhibitors from around the world, including Chinese tech companies such as Sugon, Huawei and Lenovo.
An exaflop/s is one quintillion (10¹⁸) floating point operations per second. Crossing the two exaflop sustained performance barrier is an engineering feat that enables climate modelling, drug discovery and nuclear reaction design with unprecedented precision. The TOP500 is the most authoritative supercomputer ranking, updated twice a year. China's return to the top after nine years since Sunway TaihuLight shows that the technological race between China and the US remains intense.
When a machine performs two quintillion operations per second, it ceases to be just a computer. It becomes a window into the future — where weather is predicted to the week, new materials are discovered without lab experiments, and drug molecules are assembled like building blocks. LineShine did not just beat a rival — it pushed the boundaries of the possible. And if China used to catch up, today it sets the pace. While the world argues about chips and sanctions, the supercomputer in Shenzhen calculates silently. And its numbers speak louder than any political slogan.
