El Capitan has retained its title as the world’s most powerful supercomputer in the 65th edition of the Top500 list.

All three of the top systems are operated by the US Department of Energy, which faces dramatic budget cuts under the current administration. They are the only publicly disclosed exascale systems – China no longer submits new supercomputers to Top500, but is believed to operate several exascale systems.

Lawrence Livermore’s El Capitan, an HPE Cray EX255a with AMD 4th Gen Epyc 24C 1.8GHz CPUs and Instinct MI300A GPUs, reported an HPL score of 1.742 exaflops.

It is followed by Oak Ridge’s Frontier, an HPE Cray EX235a with AMD 3rd Generation Epyc 64C 2GHz CPUs and Instinct MI250X GPUs. Frontier achieved 1.353 exaflops.

Rounding out the top three is another HPE system, this time Argonne’s Cray EX-based Aurora with the Intel Exascale Compute Blade, Xeon CPU Max 9470 52C 2.4GHz, and Intel Data Center GPU Max. It squeaked into exascale, with 1.012 exaflops.

At number four is Europe’s Jupiter Booster, a partial version of the larger supercomputer being built at Germany’s Forschungszentrum Jülich campus. The BullSequana XH3000 features Nvidia GH200 Superchips for a total of 793.4 petaflops. It is set to become the first EuroHPC exascale supercomputer.

Microsoft Azure’s Eagle system comes in at number five, with Intel Xeon Platinum 8480C 48C 2GHz CPUs and Nvidia H100 GPUs. That supercomputer achieved 561.2 petaflops.

The sixth fastest supercomputer is Europe’s second most powerful: The creatively named HPC6, a 477.9 petaflops system from Italian oil giant Eni.

Japan comes in at seven, with the Arm-based Fugaku supercomputer, built by Fujitsu for Riken. It achieved 442.01 petaflops.

We’re back to Europe for the next three: Switzerland’s Alps (434.9 pflops), Finland’s Lumi (379.7 pflops), and Italy’s Leonardo (241.2 pflops). We visited Lumi earlier this year, where the team is competing for Europe’s new AI supercomputer efforts.
