Fastest supercomputer

How it was measured

The record was set on June 22, 2026, and TOP500 recognized it on its June 2026 list of the world's most powerful systems. LineShine submitted a debut score of 2.198 exaflops on the HPL benchmark, which TOP500 uses to rank systems. The run used 13,789,440 cores, and the score put the system more than 20 percent ahead of El Capitan, which ranked second.

About LineShine

LineShine is a supercomputer installed at the National Supercomputing Centre in Shenzhen, China. The Shenzhen Cloud Computing Center built it. It runs on 304-core LX2 processors based on the Armv9 architecture, and it uses the LingQi interconnect and Kylin OS. It is the first China-based system to lead the TOP500 since Sunway TaihuLight in 2017. It also ranks first on the HPCG benchmark with 22.00 petaflops, and it is the fifth exascale system on the list. The system also marks China's return to the TOP500 list.

The record before this one

Before LineShine, El Capitan at Lawrence Livermore National Laboratory in California held the top spot with 1.809 exaflops on HPL. Frontier, at Oak Ridge National Laboratory in Tennessee, ranks third at 1.353 exaflops, and Aurora, at Argonne National Laboratory in Illinois, ranks fourth at 1.012 exaflops. On the HPL-MxP mixed-precision benchmark, LineShine placed fourth at 7.92 exaflops. AI cloud companies rarely enter the TOP500, so some hyperscale data centers could be viewed as more powerful than any listed system, depending on the benchmark.
