With over three decades of tracking the progress of high performance computing, the TOP500 lists continue to provide a reliable historical record of supercomputers worldwide. The lists lay out critical HPC metrics across all of its 500 machines and draw a rich picture of the state of the art in terms of performance, energy consumption, and power efficiency. The TOP500 now features an HPCG ranking, which measures machines’ performance using irregular accesses to memory and fine-grain recursive computations—the very factors that dominate real-world, large-scale scientific workloads.

In November 2024, the 64th TOP500 list was unveiled at SC24 in Atlanta, Georgia. The U.S. maintained its dominance with the debut of El Capitan, the third exascale system, installed at Lawrence Livermore National Laboratory. Built by HPE with AMD processors, El Capitan claimed the top spot with 1.742 exaflop/s on the HPL benchmark. With this, the top three systems—El Capitan, Frontier at Oak Ridge, and Aurora at Argonne—are now all exascale-class machines at U.S. Department of Energy facilities. Frontier, the leader since 2022, now ranks second, while Aurora, now fully operational, takes third place.
