The ISC High Performance 2026 conference in Hamburg, Germany (June 22–26) delivered several major stories that reshaped the supercomputing landscape. While China's LineShine stunned the industry by taking the TOP500 No. 1 spot without using any GPUs, NVIDIA still dominates the list with 81% of all systems. Europe also announced its largest-ever AI supercomputer expansion, and NVIDIA previewed its next-generation Vera Rubin platform.
China's LineShine Takes the TOP500 Crown — With No GPUs
The 67th TOP500 list, released June 23, 2026, saw China's LineShine system at the National Supercomputer Center in Shenzhen debut at No. 1, displacing the US' El Capitan system . It achieved 2.198 FP64 exaflops on the High Performance Linpack (HPL) benchmark — the first system ever to sustain more than 2 exaflops of double-precision performance .

At ISC High Performance 2026, China's LineShine supercomputer shocked the world by taking the No.
Crucially, LineShine uses only custom Armv9-based CPUs (Huawei LX2 processors with 304 cores each) and no GPUs. It is built entirely from domestic Chinese chips, networking, and software . The system consumed 42.22 MW of power and delivered a performance-per-watt of 52.07 GFLOPS/W, below El Capitan's 60.94 GFLOPS/W .
Experts noted the result demonstrates China's ambition for self-sufficiency in computing systems rather than AI competitiveness, since GPU-accelerated systems remain better suited for AI workloads . LineShine also topped the HPCG (High-Performance Conjugate Gradient) benchmark with 22.00 HPCG-Petaflop/s and the HPL-MxP benchmark with 7.92 exaflops .
NVIDIA's Dominance: TOP500, Green500, and Grace CPU Adoption
Despite losing the No. 1 spot, NVIDIA's overall presence on the TOP500 grew to 81% — over 400 of the 500 systems use NVIDIA technology . Key metrics from NVIDIA's official blog :
90% of systems new to the TOP500 run on NVIDIA technology.
26 systems on the list now use the NVIDIA Grace CPU, up 8 from the previous list.
238 systems use NVIDIA GPUs; 376 systems use NVIDIA networking (mostly Quantum InfiniBand).
Grace CPU shipments total nearly 2.5 million units .
The top 8 systems on the Green500 energy-efficiency ranking run on NVIDIA GPUs, and 9 of the top 10 use NVIDIA technologies .
The No. 1 system on the Green500 is KAIROS, a Bull Sequana XH3000 system using a single NVIDIA Grace Hopper GH200 Superchip, achieving 73.3 gigaflops per watt .
Europe's Record 35 New AI Supercomputers
On June 22, 2026, NVIDIA announced the largest-ever European AI supercomputing expansion: 35 new AI/HPC systems across 23 countries, built on Blackwell and Hopper architectures . Key details:
The infrastructure will serve over 3 million researchers.
Systems will support climate science, healthcare, clean energy, decarbonization, and quantum computing .
The total AI computing capacity across these systems is described as delivering 800 AI exaflops, accelerating work for researchers in generative AI, climate modeling, medicine, sustainable agriculture, and energy systems .
NVIDIA AI infrastructure now powers over 90% of Europe's AI factory buildout .

Vera Rubin Platform: Rack-Scale Supercomputing for Science
NVIDIA unveiled the Vera Rubin platform, a rack-scale supercomputing architecture designed to converge high-precision simulation, AI, and data analytics. It delivers approximately 7 exaflops of AI performance and 5 petaflops of native double-precision (FP64) performance . The platform is intended for the next generation of TOP500-class systems, combining FPGA-based double-precision engines with NVIDIA's full-stack CUDA-X and AI platform capabilities .
According to NVIDIA CEO Jensen Huang, the platform is designed to function as a new scientific instrument capable of accelerating research in climate modeling, drug discovery, and energy systems .
Broader Implications for Applied Research
NVIDIA and EuroHPC explicitly framed the 35-system expansion around decarbonization, clean energy, and quantum computing research . The quantum-GPU computing track was a featured theme at the conference, with European centers including CINECA, Fraunhofer FOKUS, BSC, and Jülich expanding quantum-GPU infrastructure . The systems are designed to accelerate climate modeling, healthcare, biotechnology, sustainable agriculture, and government AI services .
