{"slug": "top500-names-new-number-one-at-isc-26", "title": "TOP500 Names New Number One at ISC'26", "summary": "China's LineShine supercomputer, powered entirely by indigenous LX2 CPUs, claimed the #1 spot on the 67th TOP500 list at ISC'26 with 2.198 Exaflops, surpassing El Capitan by 20%. However, the system lacks GPU accelerators, highlighting a divergence from AI-focused HPC where NVIDIA dominates 81% of TOP500 systems and all top Green500 entries.", "body_md": "China's return to the TOP500 summit after nine years matters for geopolitics and HPC procurement, but carries a critical caveat for AI practitioners: LineShine is entirely CPU-based with no GPU accelerators. At ISC'26 in Hamburg, the 67th TOP500 list debuted with LineShine, installed at the National Supercomputing Centre in Shenzhen, at #1 with 2.198 Exaflops sustained (Rmax) -- more than 20% ahead of former leader El Capitan -- using roughly 13.8 million cores of the indigenous LX2 processor. It also tops the HPCG benchmark at 22.004 Petaflops, confirming it is not a LINPACK-only system. Meanwhile NVIDIA continues to dominate AI-oriented HPC: 81% of TOP500 systems and all of the Green500's top 8 run on NVIDIA hardware. The benchmark that matters for AI training throughput tells a different story than the one China just won.", "url": "https://wpnews.pro/news/top500-names-new-number-one-at-isc-26", "canonical_source": "https://letsdatascience.com/news/top500-names-new-number-one-at-isc26-b2b336a6", "published_at": "2026-06-28 19:38:00+00:00", "updated_at": "2026-06-28 23:08:45.662595+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-chips", "ai-infrastructure"], "entities": ["TOP500", "LineShine", "National Supercomputing Centre in Shenzhen", "LX2", "El Capitan", "NVIDIA", "Green500", "ISC'26"], "alternates": {"html": "https://wpnews.pro/news/top500-names-new-number-one-at-isc-26", "markdown": "https://wpnews.pro/news/top500-names-new-number-one-at-isc-26.md", "text": "https://wpnews.pro/news/top500-names-new-number-one-at-isc-26.txt", "jsonld": "https://wpnews.pro/news/top500-names-new-number-one-at-isc-26.jsonld"}}
