China is now home to the world’s fastest supercomputer. A new system called LineShine has secured the top position in the latest global supercomputer rankings. This achievement ends the lead held by an American supercomputer, which had remained in first place since late 2024.
The announcement came on June 23 at a major computer conference in Hamburg, Germany. This event releases the TOP500 ranking twice a year, which tracks the world’s 500 most powerful supercomputers. On its first appearance in the ranking, LineShine took the number one spot and replaced the American supercomputer El Capitan as the world’s fastest machine.
LineShine is located at the National Supercomputing Centre in Shenzhen(China). The system delivers a performance of 2.198 exaflops. That means it handles more than two quintillion math tasks every single second. This makes it the most powerful supercomputer ever built. It beats the previous top system, a US machine called El Capitan, by 20 percent.
El Capitan is located at the Lawrence Livermore National Laboratory in California. The US government uses this system to design and maintain its nuclear weapons program. El Capitan had held the top position in the global rankings since November 2024, but it has now moved down to second place.
What makes LineShine really special is how it works. Most of the world’s top supercomputers depend on advanced chips made by companies like Nvidia. But, LineShine does not use even a single chip from Nvidia, Intel, or AMD. China built the system using its own custom processors, the LingKun computing platform, the LingQi connection system, and the Kylin operating system. Every single part inside it comes from China.
This achievement is especially significant because the United States has restricted China’s access to advanced computer chips for years. Many experts believed those restrictions would slow China’s progress in supercomputing. However, LineShine shows that China has continued to move forward by developing and using its own technology.
However, LineShine does have one limitation. The system is not the world’s strongest machine for AI tasks and ranked fourth in tests that measure AI computing power. It also does not use advanced AI chips, because the technology needed to make those chips remains restricted by US export controls. Still, LineShine delivers unmatched performance in scientific computing tasks, including climate research, space exploration, and complex physics problems.
China last held the top position in 2017, when the Sunway TaihuLight supercomputer ranked as the world’s fastest supercomputer. After that, China stopped submitting its systems to the TOP500 list due to concerns over US trade restrictions. LineShine marks a major achievement because China built the entire system with locally developed technology.
Jack Dongarra, one of the organizers of the TOP500 rankings, said the result shows that China remains a strong competitor in advanced computing even with US export restrictions on high-end semiconductor technology.
The latest rankings show that five supercomputers have now reached the highest level of computing performance. Three of them are in the United States, while China and Germany each have one. The race for computing power between the world’s two biggest nations shows no signs of slowing down.
