Top 10 Supercomputers Expected to Dominate at PetaFLOPS and Exascale Levels in 2025
In a thrilling turn of events, the world's fastest supercomputer as of June 2025 is none other than El Capitan, located at the Lawrence Livermore National Laboratory in the United States. El Capitan boasts an impressive Rmax score of 1.742 exaFLOPS, making it the first European supercomputer to claim the top spot in the TOP500 ranking.
El Capitan, tied together by the Slingshot-11 network, is built using HPE's Cray EX255a design with AMD 4th-gen EPYC CPUs and Instinct MI300A accelerators. This powerful machine is not only Europe's new flagship supercomputer but also the continent's highest-ranked system, adding a significant boost to the European supercomputing landscape.
Joining El Capitan in the elite tier is the JUPITER Booster, another European powerhouse located in Germany. With an Rmax score of 793.4 petaFLOPS, JUPITER Booster has secured its place in the TOP500 ranking in June 2025, making it a new heavyweight supercomputer in the European scene.
Meanwhile, China, a dominant force in global supercomputing, has decided to stop submitting data to the TOP500, keeping the true scale of its systems a mystery. This move adds an extra layer of intrigue to the global supercomputing rivalry, as the world waits to see what China's next move will be.
The LUMI supercomputer system, put into operation in 2020, is another European contender with an Rmax score of 379.7 petaFLOPS. LUMI, located in Finland, is built on HPE Cray EX235a with AMD EPYC + Instinct MI250X, making it a formidable player in the supercomputing world.
In the United States, Aurora, located at the Argonne National Laboratory, has an Rmax score of 1.012 exaFLOPS, while Frontier, located at the Oak Ridge National Laboratory, has an Rmax score of 1.353 exaFLOPS. Both supercomputers are built using HPE Cray EX235a cabinets, AMD EPYC CPUs, and Instinct MI250X GPUs, on Slingshot-11.
Microsoft Azure's Eagle, a top-five supercomputer, has an Rmax score of 561.2 petaFLOPS, making it the highest-ranked cloud supercomputer yet again this cycle. Leonardo, located at the EuroHPC / CINECA in Italy, has an Rmax score of 241.2 petaFLOPS, holding onto a top-ten slot in 2025 as newer Grace-Hopper and MI300A systems climb above it.
As we look to the future, the next milestone for supercomputers is expected to be zeta-class supercomputers, capable of a staggering 1,000 exaFLOPS. Japan has already set its sights on this frontier with plans for Fugaku Next, which is expected around 2030.
