China’s Supercomputer Surpasses US
In a notable shift, China’s supercomputer system has outpaced the U.S., becoming the fastest in the world, according to an industry list published on Tuesday in Hamburg, Germany. This is the first time since 2017 that China has taken the lead in supercomputer rankings.
The newly crowned champion, LineShine, was developed by the Shenzhen Cloud Computing Center. It has overtaken El Capitan, which had been dominating the field from the Lawrence Livermore National Laboratory in California since November 2024.
Previously, China last held the top position back in 2017 with the Sunway Taihu Guang. Since then, the U.S. had consistently been at the forefront after dethroning Japan’s Fugaku in 2021.

LineShine stands out because, unlike most high-performance supercomputers, it does not utilize a graphics processing unit (GPU) from Nvidia. Instead, it relies on a conventional central processing unit (CPU) and operates on over 13 million CPUs altogether.
The TOP500 list uses a benchmark known as the High Performance Linpack (HPL) to evaluate supercomputer performance, pushing the systems to their limits through extensive calculations. It’s worth noting that while this metric provides an insight into a system’s linear equation-solving capabilities, it doesn’t encapsulate the overall performance in a single number.
TOP500 concluded that LineShine outperformed El Capitan by 20%, marking a significant achievement. With this advancement, LineShine becomes the fifth supercomputer in history to showcase exascale capabilities, meaning it can execute one quintillion calculations per second.

Despite China’s new leadership in supercomputing, the U.S. still maintains strong representation in the overall rankings, with El Capitan, Frontier, and Aurora securing second, third, and fourth places respectively.
This update coincided with President Donald Trump’s recent signing of an executive order aimed at advancing quantum computing, signaling the U.S.’s intent to enhance its capabilities in emerging technologies, which many believe to be transformative for the computing world.
