China has reportedly surpassed the United States to become home to the world’s most powerful supercomputer, marking a significant shift in global computing leadership.
China’s “Lian Shan” Supercomputer Tops Global Rankings, Surpassing US System
China’s “Lian Shan” supercomputer has reportedly claimed the top spot in the global TOP500 rankings, overtaking leading systems in the United States.
The achievement is being seen as a major milestone, as the system has been developed using locally designed chips, networking equipment, and software, reflecting China’s push for technological independence.
This marks the first time since 2017 that China has reached number one in the global supercomputer rankings. In earlier years, Chinese systems often depended partly on imported components.
Despite strict US export controls on advanced technology, China has continued developing domestic alternatives, which were used in building this high-performance system.
The project is being described as a significant national effort aimed at demonstrating China’s ability to compete in advanced computing without relying on US-made hardware.
The “Lian Shan” system reportedly uses Huawei-developed chips along with locally produced infrastructure and software.
Supercomputers differ from standard computers as they rely on thousands of interconnected processors working together to handle extremely complex scientific and computational tasks.
Previously, the “El Capitan” supercomputer in the United States held the top position for about 18 months.
Based on performance measured in exaflops, the Chinese system is reported to deliver around 2.2 exaflops per second, compared to approximately 1.8 exaflops per second for the US system.
While the individual components may not surpass Western chips in performance, the overall system achieves higher output through large-scale integration—though this comes with higher energy consumption.
The “Lian Shan” supercomputer reportedly consumes around 42 megawatts of power, about 40% more than its US counterpart.
