List of Most Powerful Supercomputers in the World
The world's fastest supercomputers ranked by sustained performance on the High Performance Linpack (HPL) benchmark, based on the November 2025 TOP500 list.
The world's most powerful supercomputers are ranked twice a year by the TOP500 project, which measures sustained performance on the High Performance Linpack (HPL) benchmark in petaflops — quadrillions of calculations per second. As of the November 2025 list, four machines have crossed the exascale threshold of one quintillion calculations per second, three of them at U.S. Department of Energy laboratories and the fourth, JUPITER Booster, becoming Europe's first exascale system. El Capitan at Lawrence Livermore National Laboratory holds the top spot at 1.809 exaflops, while accelerated systems built on AMD, Intel, and NVIDIA hardware dominate the upper ranks. These machines power nuclear stockpile stewardship, climate modeling, drug discovery, and large-scale AI research.
