Overview
- The Top500 update published on June 24, 2026 placed LineShine at number one with an HPL measurement of about 2.198–2.2 exaflops, overtaking the U.S. system El Capitán.
- LineShine is installed at the National Supercomputing Centre in Shenzhen and is built with domestically designed LX2 CPUs, a proprietary LingQi interconnect and the Kylin operating system.
- The ranking reflects performance on the HPL benchmark, a linear algebra test that rewards CPU-oriented, sequential workloads and does not directly measure GPU-style parallel training used for most modern AI models.
- The United States still holds the majority of top slots on the list, and many cloud providers that run GPU-heavy AI systems do not submit their machines to Top500, so public rankings understate overall AI compute capacity.
- Analysts say the result signals China’s push for semiconductor self-reliance in response to U.S. export controls and could accelerate domestic chip and system investment, but it does not by itself change who leads in AI model training.
