AMD Powers Four Of Ten Fastest Supercomputers In Latest Top500 Rankings

AMD has strengthened its position across the latest Top500 and Green500 supercomputer rankings, with its technology now powering 191 systems on the Top500 list – an 11 per cent increase year-over-year.

The company’s EPYC CPUs and Instinct GPUs are present in four of the ten fastest supercomputers and four of the ten most energy-efficient systems on the respective lists. AMD also powers 41 per cent of the new systems added to this year’s Top500 rankings.

The results were highlighted at ISC 2026, the high-performance computing conference held in Hamburg, Germany.

Top500 Presence

AMD-equipped systems holding positions in the Top500’s top ten include El Capitan at number two, Frontier at number three and the newly deployed HPC7 system at Eni at number six.

AMD Instinct GPUs power 42 per cent of the total computing performance (FLOPs) across the top ten systems on the list.

Of the 44 new systems added to the June 2026 Top500 list, AMD powers 18 of them, making it the most represented silicon vendor among new entrants.

The first systems powered by AMD Instinct MI355X GPUs have also appeared on the list. Two newly announced systems at the University of Cambridge are ranked at numbers 67 and 68.

Energy Efficiency Gains

On the Green500 list, which ranks the most energy-efficient supercomputers, AMD-powered systems hold four positions in the top ten: Otus at number five, Capella at number six, AMD Ouranos at number nine and Portage at number ten.

AMD technology powers 56 per cent of the top 50 systems on the Green500 list, reflecting the company’s focus on performance-per-watt alongside raw computing power.

Advancing European Sovereign AI

AMD highlighted its growing role in European sovereign AI and exascale computing through several deployments across the region.

Eni’s new HPC7 supercomputer, ranked sixth on the Top500, is one of Europe’s larger industrial HPC systems. Building on the earlier HPC6 system, which sits at number eight, Eni is using the AMD-powered infrastructure to support AI, modelling and simulation workloads aimed at accelerating energy research.

LUMI, operated by the EuroHPC Joint Undertaking and hosted by CSC in Finland, holds the number 11 position on the Top500 and has become a key resource for European AI research, providing access to computational resources for both traditional HPC and AI workloads.

GENCI, France’s national high-performance computing agency, is advancing its HPC and AI capabilities with AMD technology. This includes the development of Alice Recoque, France’s first exascale supercomputer, which will be powered by AMD Instinct MI430X GPUs and 6th Gen AMD EPYC CPUs. The system is intended to serve as both an HPC resource and an AI Factory.

FP64 Computing And The MI430X GPU

AMD also used the conference to highlight the continued importance of double-precision (FP64) computing for scientific applications. Whether modelling climate systems, simulating advanced materials, designing aircraft or exploring nuclear fusion, accuracy remains essential for producing reliable results.

At HPC User Forum 2026, AMD previewed the Instinct MI430X GPU, designed to address the growing need for both AI acceleration and HPC performance.

AMD projects the Instinct MI430X GPU will deliver more than 200 teraflops (TFLOPs) of native FP64 performance, which would set a new benchmark for simulation, modelling and AI-driven scientific computing. This level of performance is relevant as AI and HPC workloads increasingly converge on the same infrastructure.
