The new Chinese supercomputer LineShine has claimed the top spot in the TOP500 ranking, surpassing the US system El Capitan by more than 20%. This achievement marks China's return to the forefront after nearly a decade. The most striking feature is that LineShine does not use GPUs but relies solely on CPUs, defying global trends in high-performance computing.
LineShine Achieves 2,198 Exaflops with LX2 Processors Only
LineShine was built entirely with components and software developed in China. Its architecture is based on the LingKun platform and integrates approximately 45,000 LX2 processors, each with 304 cores and a clock speed of 1.55 GHz. The system delivers 2,198 exaflops, meaning it can perform over 2 quintillion operations per second, with a power consumption of about 42.2 megawatts. The nodes are connected via the high-speed LingQi network, designed to minimize latency and accelerate data exchange. The entire system runs on Kylin OS, a Linux-based operating system widely used in China's scientific and government computing infrastructure.

Absence of GPUs Marks an Unprecedented Technological Shift
Unlike modern supercomputers that leverage GPUs for parallel computing acceleration, LineShine relies exclusively on CPUs. This architectural choice is a direct response to US export restrictions on advanced chips and components, particularly GPUs. China has thus invested in innovative architectures to compete without access to key American technologies. LineShine proves that world-class performance is achievable even without GPUs, using massively optimized CPU cores.
US Restrictions Push Beijing Toward Technological Self-Sufficiency
The rise of LineShine is closely tied to geopolitical tensions between China and the United States. During the Trump and Biden administrations, Washington imposed strict export controls on hardware and software for advanced computing to slow China's technological progress. Beijing responded with similar measures, incentivizing domestic production. Current restrictions, intensified under the new Trump administration, have particularly targeted GPUs and AI chips. LineShine thus represents not only a scientific milestone but also a political statement: China can thrive despite Western technological barriers.

Comparison with El Capitan and Implications for the TOP500 Ranking
El Capitan, located at Lawrence Livermore National Laboratory in California, had held the top spot since 2024. With performance about 20% lower than LineShine, the US system has been decisively surpassed. The TOP500, published every six months since 1993, evaluates theoretical and real-world performance as well as energy efficiency. The historical US dominance is now challenged by China's ability to innovate under embargo.

LineShine exemplifies how restrictions can spur forced innovation. China has shown that a fully domestic hardware and software ecosystem can compete at the highest level. As global technological competition intensifies, LineShine's result may redefine supercomputer development strategies worldwide.
