China’s LineShine Tops TOP500, Surpassing U.S. El Capitan at ISC 2026 in Hamburgo

China’s LineShine system has taken first place on the TOP500 list of the world’s most powerful supercomputers, published for June 2026 during the ISC 2026 conference in Hamburgo.

The system, installed at the National Supercomputing Centre in Shenzhen, reached 2,198 exaflops in the High Performance Linpack (HPL) benchmark, surpassing the American El Capitan, which fell to second place.

LineShine is built on the LingKun platform with LX2 processors of 304 cores running at 1.55 GHz, connected via the proprietary LingQi interconnect and running Kylin OS.

The new ranking also places El Capitan at 1,809 exaflops, Frontier at 1,353 exaflops, Aurora at 1,012 exaflops, and JUPITER Booster at exactly 1 exaflop.

The TOP500 edition described LineShine as the first system to exceed two exaflops in sustained double precision using only CPUs.

Multiple outlets framed the result as a return to the top since 2017, with the system debuting directly at number one on the TOP500 list for June 2026.

Boursorama, citing Reuters, said the LineShine system “clinches first place in the TOP500 ranking” but “only ranks fourth in a test designed to simulate AI-like computing tasks.”

The same Reuters-based framing described why that gap matters, noting that “Most of these companies do not seek to appear in the TOP500 ranking” and that cloud supercomputers are oriented toward AI workloads.

El Chapuzas Informático added that LineShine ranks first in the HPCG benchmark with 22 petaflops, while warning that “one should not confuse having the world’s most powerful supercomputer with also leading in AI-related workloads.”

In the June 2026 TOP500 context, the CPU-only design was presented as a defining technical choice, with LineShine’s HPL-MxP result placed at fourth with 7.92 exaflops.

The shift in leadership was tied to technology sovereignty themes, with several reports emphasizing that LineShine is built with Chinese hardware and described as a message of autonomy in computing systems.

Argentinisches Tageblatt said the TOP500 ranking placed LineShine at the top with 2,198 exaflops and described it as “the first time since 2017 that a system Chinese encabeza esta clasificación internacional.”

Reuters-based coverage in Boursorama quoted Jimmy Goodrich saying, “If hyperscalers submitted their systems, this ‘world’s fastest system’ would not rank among the top five,” linking the public ranking to what it measures.

The same Reuters-based account also reported that China had suspended its TOP500 submissions in 2023 after years of export controls tied to chips and computing, and it noted that the LineShine system contains no leading-edge AI chips.

Across the coverage, the stakes were presented as both technical and political, with the TOP500 described as a snapshot of scientific computing while other AI-focused systems were said not to participate in the public ranking.
