China's LineShine Hits 2.2 Exaflops, Tops US Supercomputer

6/24/2026

Summary

LineShine Tops

On June 22, China’s LineShine became the world’s fastest supercomputer, overtaking the U.S. El Capitan at the International Supercomputing Conference in Hamburg.
LineShine delivered 2.198 exaflops, performing more than 2 quintillion calculations per second using only CPUs.
The system employs about 13 million processors and consumes roughly 42.2 MW of electricity.
El Capitan fell to second with 1.809 exaflops, leaving the U.S. with three of the top four spots while Germany’s Jupiter dropped to fifth.

Summary

LineShine Ranks Fourth

LineShine placed fourth in an AI-focused benchmark that simulates artificial-intelligence workloads, trailing the leading systems in that category.
The National Supercomputing Centre says LineShine already supports climate modelling, engineering simulations, drug discovery, neuroscience research and AI development projects.
Analysts warn that the TOP500 ranking, which relies on the legacy High-Performance Linpack test, fails to reflect a nation’s AI capabilities because many top AI platforms are excluded.

Summary

LineShine Shows Efficiency

LineShine draws about 42.2 MW and delivers 52.07 gigaflops per watt, behind El Capitan’s 60.94 gigaflops per watt.
The Green500 ranking shows energy efficiency unchanged, with France’s KAIROS system leading at 73.28 gigaflops per watt.
LineShine reaches roughly 80 percent of its 2.736 exaflop/s peak, surpassing U.S. exascale machines that sustain only 50-65 percent of peak power.
Its LingQi interconnect and Kylin operating system manage power, keeping cluster consumption comparable to a small city.

History

Historical Context

IBM’s Deep Blue defeated world champion Garry Kasparov 3½–2½ in a six-game match in New York in May 1997, the first tournament loss of a reigning champion by a computer. The victory earned IBM $700,000 and sparked a national prestige race that later drove China’s LineShine supercomputer and today’s AI-driven exascale competition.
