AMD chips power 191 supercomputers as rankings shift

AMD chips are used in 191 systems on the latest Top500 and Green500 supercomputing rankings. Its technology now appears in four of the world's 10 fastest supercomputers.

The updated rankings show AMD expanding its presence across both performance and energy-efficiency tables. Company figures show its processors and accelerators power 41% of the new systems added to this year's Top500 list, with 18 of the 44 newly listed machines using AMD technology.

AMD is represented in four of the Top500 top 10, including El Capitan at No. 2, Frontier at No. 3 and the newly deployed HPC7 at No. 6. AMD Instinct GPUs also account for 42% of the floating-point operations per second represented by the top 10 systems.

The latest Green500 rankings, which measure energy efficiency in supercomputing, also show a strong AMD presence. Four AMD-based systems are in the Green500 top 10: Otus at No. 5, Capella at No. 6, AMD Ouranos at No. 9 and Portage at No. 10.

Across the 50 most energy-efficient supercomputers, AMD technology is used in 56% of systems, giving the chipmaker a larger footprint in the efficiency rankings as operators weigh electricity use alongside raw computing output.

European growth

Much of AMD's latest update focused on Europe, where several supercomputing projects are using its processors and graphics accelerators for research and industrial workloads. The company linked that growth to demand for domestic AI infrastructure and exascale computing in the region.

Eni's HPC7 system was highlighted as one of Europe's leading industrial high-performance computing installations. Ranked No. 6 on the Top500, it follows HPC6, ranked No. 8, and is used for AI, modelling and simulation tasks tied to energy research.

The University of Cambridge also appears in the latest list with what AMD described as the first systems built around its Instinct MI355X GPUs. Those two systems entered the Top500 at Nos. 67 and 68.

Elsewhere in Europe, LUMI remains one of the region's most prominent supercomputers. Hosted in Finland and operated by the EuroHPC Joint Undertaking with CSC, it is ranked No. 11 and is used for both traditional high-performance computing and AI workloads.

France's national high-performance computing agency, GENCI, is also expanding its use of AMD technology. This includes Alice Recoque, described by the company as France's first exascale supercomputer, which is set to use AMD Instinct MI430X GPUs and sixth-generation EPYC CPUs.

AI and HPC

The figures come as chipmakers and system operators increasingly treat AI and high-performance computing as overlapping markets rather than separate ones. Large scientific systems are now expected to handle both traditional simulation work and newer AI tasks on shared infrastructure.

AMD said many scientific applications still depend on double-precision, or FP64, computing. That includes climate modelling, advanced materials, aircraft design and nuclear fusion, where computational accuracy remains central to the results.

The company also pointed to the next generation of its accelerator products as part of that strategy. It said the Instinct MI430X GPU is aimed at users who need both AI processing and high-end HPC performance, and projected that the chip would deliver more than 200 teraflops of native FP64 performance.

The claim reflects how vendors are trying to serve converging AI and scientific workloads with the same silicon. In practice, the balance between training AI models, running inference and carrying out large-scale simulations has become a central issue for research labs, industrial users and national computing programmes.

Broader Top500 data suggests AMD has strengthened its position in a market long shaped by competition over processor performance, accelerator adoption and power efficiency. With 191 systems now listed and year-on-year growth of 11%, the company has increased its share of newly installed supercomputers while also gaining ground in energy-efficient deployments.

Of the 44 new systems on the latest Top500 list, AMD powers 18, the most of any silicon vendor.
