The supercomputer race just got a seismic shakeup. On June 28, 2026, the 67th edition of the TOP500 list dropped, and for the first time in nearly a decade, a Chinese system sits at #1.
Meet LineShine — a 2.198 Exaflop/s beast built by the Shenzhen Cloud Computing Center and installed at the National Supercomputing Centre in Shenzhen (NSCS). It pushes El Capitan (1.809 Exaflop/s) to second place and marks the first time a Chinese machine has topped the list since Sunway TaihuLight back in 2017.
The Specs That Matter
| Metric | LineShine |
|---|---|
| Rmax (HPL) | 2.198 Exaflop/s |
| Rpeak | 2.736 Exaflop/s |
| Cores | 13,789,440 |
| Processor | Custom LingKun LX2 — 304 cores @ 1.55 GHz |
| Interconnect | Proprietary LingQi |
| OS | Kylin OS |
| Power | 42,220 kW |
| HPCG | 22.00 Petaflop/s (also #1) |
What Makes LineShine Special?
LineShine isn’t just fast — it’s differently fast. While every other Exascale system in the top 5 (El Capitan, Frontier, Aurora, JUPITER) relies on GPU accelerators (AMD MI300A, Intel GPU Max, NVIDIA GH200), LineShine achieves its 2.198 Exaflop/s using a CPU-only design. Its custom “LingKun” platform packs 304-core LX2 processors running at just 1.55 GHz — relying on sheer parallelism rather than clock speed or specialized accelerators.
This CPU-only approach means LineShine punches above its weight on the HPL benchmark but shows a more modest 3.6x speedup on mixed-precision (HPL-MxP), landing at #4 with 7.92 Exaflop/s — behind GPU-heavy competitors.
The system also tops the HPCG benchmark at 22 Petaflop/s, which measures real-world application performance — a strong indicator that this isn’t just a theoretical benchmark queen.
The New Exascale Landscape
| Rank | System | Country | Rmax | Cores |
|---|---|---|---|---|
| #1 | LineShine (LingKun) | 🇨🇳 China | 2.198 EF | 13.8M |
| #2 | El Capitan (HPE Cray) | 🇺🇸 USA | 1.809 EF | 11.3M |
| #3 | Frontier (HPE Cray) | 🇺🇸 USA | 1.353 EF | 9.1M |
| #4 | Aurora (HPE Cray / Intel) | 🇺🇸 USA | 1.012 EF | 9.3M |
| #5 | JUPITER Booster (Bull) | 🇪🇺 Germany | 1.000 EF | 4.8M |
All five are Exascale-class — a milestone that seemed impossible just a few years ago. The US still holds three of the top five spots, but China’s return to #1 signals the supercomputing race is far from over.
Why This Matters
Supercomputing power directly correlates with a country’s ability to lead in AI training, climate modeling, drug discovery, and defense simulations. China’s LineShine breakthrough — using entirely domestic processors and interconnects — demonstrates that the country can compete at the highest level despite export restrictions on advanced chips.
FAQ
Is LineShine the world’s fastest computer ever?
Yes — at 2.198 Exaflop/s on the HPL benchmark, it’s the most powerful system ever measured by TOP500 standards.
How much does it cost to run?
LineShine draws 42.22 MW of power. At average industrial electricity rates in China, that’s roughly $25-30 million per year just for electricity.
When will the next TOP500 list come out?
The TOP500 list is published twice a year — expect the next edition in November 2026. The race between China and the US is expected to intensify.
Can I access LineShine for research?
LineShine is installed at the National Supercomputing Centre in Shenzhen and is expected to be available for approved research projects through China’s national supercomputing network.
Final Thoughts
China’s return to #1 on the TOP500 is a big deal — but the full story is more nuanced. While LineShine dominates the HPL benchmark, GPU-powered systems still lead in mixed-precision workloads critical for AI. The real winner here is competition: with five Exascale systems now online, the pace of innovation in HPC has never been faster.
