China's CPU-only LineShine Supercomputer Topps TOP500 List with 2.198 Exaflops
China's LineShine supercomputer, installed at the National Supercomputing Centre in Shenzhen, has claimed the top spot on the 67th TOP500 list with 2.198 exaflops of double-precision performance using only domestically designed CPUs (13.8 million cores), pushing AMD-powered El Capitan into second place by over 20%. Built on the LingKun platform with no GPUs or accelerators, LineShine uses Armv9-based LX2 processors and runs the homegrown Kylin OS. The machine also ranked first on the HPCG benchmark but only fourth on mixed-precision AI workloads. The submission marks a strategic shift for China, which had kept its fastest systems off the list since 2021 due to US sanctions. The all-domestic design and lack of public funding reduce political exposure, making disclosure less risky.

In a significant development in high-performance computing, China's LineShine supercomputer, located in Shenzhen, has claimed the top spot in the latest TOP500 ranking, displacing the US's El Capitan. This marks the first time since 2017 that a Chinese system has held the title of the world's most powerful supercomputer, underscoring the intensifying technological competition between the two nations. The shift highlights China's continued investment and progress in supercomputing capabilities, challenging long-standing US dominance in the field.
Fortune | FORTUNEChina's LineShine Supercomputer Overtakes US to Claim World's Fastest Title
China has reclaimed the title of the world's fastest supercomputer, surpassing the United States for the first time since 2017. The Chinese supercomputer, named LineShine, has taken the number one spot on the TOP500 list, a ranking of the world's most powerful supercomputers. This development marks a significant shift in high-performance computing (HPC) leadership, with China leapfrogging the best US machines. The news has been reported by multiple major outlets including Al Jazeera, The Guardian, The New York Times, and HPCwire. Additionally, the competitive landscape in HPC is noted, with AMD and Nvidia being closely matched in the supercomputing sector. The achievement underscores China's growing technological capabilities and its strategic focus on advancing computing power for research, defense, and economic applications.
Top stories - Google NewsChina's LineShine Supercomputer Tops World FP64 Ranking, Edges Past US El Capitan
China's LineShine supercomputer, deployed at the National Supercomputing Centre in Shenzhen, has claimed the top spot in the Top 500 list for double-precision (FP64) performance, achieving 2.198 ExaFLOPS on the Linpack benchmark. It is the first machine to surpass 2 ExaFLOPS using only CPUs, powered by 13.79 million cores from semi-custom 304-core LX2 processors (Armv9 architecture) and the proprietary LingQi interconnect, consuming 42.2 MW. While LineShine leads in FP64 and the HPCG benchmark, its mixed-precision performance (7.92 EFLOPS) trails behind US systems El Capitan, Frontier, and Aurora, limiting its AI training efficiency. The article notes that China's submission of results signals confidence in domestic technology independence from US export controls.

China's LineShine supercomputer, built by the Shenzhen Cloud Computing Center using semi-custom 304-core LX2 processors (Armv9), has claimed the top spot in the Top 500 list with 2.198 FP64 ExaFLOPS, making it the first machine to sustain over 2 ExaFLOPS using only CPUs. It also leads the HPCG ranking. However, its mixed-precision performance (7.92 EFLOPS) lags behind US systems El Capitan, Frontier, and Aurora, limiting its AI training capability due to a lower FP64-to-mixed-precision uplift (3.6X) than systems with dedicated accelerators. The system consumes 42.2 MW of power, achieving 52.07 GFLOPS/W efficiency, lower than El Capitan's 60.94 GFLOPS/W. Opined as a demonstration of confidence in domestic technology independent of US export controls.
