LineShine becomes – China’s LineShine, installed at the National Supercomputing Center in Shenzhen, has taken the No. 1 spot on the TOP500 ranking by delivering 2,198 exaflops—over 20% more processing capacity than the US system El Capitan, which held the top spot since 2024.
For months, the TOP500 chart has acted like a scoreboard for the world’s fastest machines—updated every six months with standardized benchmarks. This time, the top spot changed hands in a way that feels less like routine tech progress and more like a clear message.
China now has the world’s fastest supercomputer. The system, known as LineShine, is installed at the National Supercomputing Center in Shenzhen. It has displaced the United States’ El Capitan from the No. 1 position in the TOP500 ranking in terms of computing power.
The shift comes at a moment when Beijing and Washington are locked in an intense competition for technological supremacy. backed by high tariffs and restrictions on a wide range of hardware components and software. LineShine’s arrival at the summit has been interpreted as proof that China’s supercomputing push can thrive even without access to certain US technologies.
LineShine doesn’t just beat a rival—it does it with numbers that leave little room for ambiguity. Benchmark results confirm that LineShine exceeds El Capitan’s processing capacity by more than 20 percent. With power consumption of approximately 42.2 megawatts. the Chinese system delivers 2. 198 exaflops. meaning it can perform more than 2 quintillion operations per second.
For TOP500, those results matter because the ranking isn’t only about theoretical speed. Since 1993. it has identified the world’s most powerful supercomputers every six months through standardized benchmarks that evaluate each system’s performance. factoring in both theoretical speed and real-world performance. as well as energy efficiency.
Historically, the TOP500 list has been dominated by US-developed systems. But LineShine returns China to first place after nearly a decade out of the top position. El Capitan—located in Livermore, California—had held the top position since 2024.
What stands out is how LineShine achieves its performance. Unlike most next-generation supercomputers, it does not use graphics processing units (GPUs). Instead. it relies exclusively on central processing units (CPUs)—components widely used in smartphones. desktop computers. and laptops. but rarely found in large-scale scientific computing systems.
Its design is also entirely rooted in domestic development. The supercomputer’s entire infrastructure is built with hardware and software developed in China. LineShine’s architecture is based on the LingKun platform and consists of roughly 45,000 LX2 processors. Each processor has 304 cores and operates at a clock speed of 1.55 GHz.
To keep the system moving fast, the nodes are connected through a high-speed network called LingQi, 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.
All of this arrives against a backdrop of escalating controls on advanced computing. During Donald Trump’s first administration and throughout Joe Biden’s presidency. the United States imposed strict export controls on components. software. and platforms related to advanced computing. aiming to slow China’s technological progress. Beijing adopted similar measures in response.
Those restrictions have intensified during Trump’s current administration. particularly through tariffs and limits on imports of GPUs. advanced chips. and other components related to artificial intelligence. AI is now a core ingredient in a significant share of the world’s most powerful supercomputers.
For China. LineShine appears built around the same pressure that pushed the race forward: when access to certain state-of-the-art resources is limited. the path to the top requires different architectures and technologies—ones capable of competing with the highest-performing US systems without leaning on the most cutting-edge imported parts.
The TOP500 update that confirms LineShine at No. 1 doesn’t just rearrange a leaderboard. It tightens the competition between two technological superpowers, where faster supercomputers aren’t only machines—they’re leverage.

So China beat the US at math computers again. Cool i guess?
El Capitan was #1 forever and now it’s just gone? Sounds like they changed the rules or the benchmarks or something. Like how is 20% even measured, wouldn’t that depend on what they load on it?
If it’s 2,198 exaflops then that’s like… basically the computer can do everything right? Also 42.2 megawatts sounds like a city block worth of electricity lol. I’m not sure why they keep calling it a scoreboard when half the stuff is classified or not real world.
Wait, I thought TOP500 was about video cards or AI chips or whatever. But they’re saying it’s exaflops and energy efficiency. So this is proof China doesn’t need US tech? Or is it just that we’re restricted from something but they’re using different software benchmarks? I don’t know, it all feels political more than science.
