Top500.org on Tuesday released its 65th list of the world's most powerful supercomputers, revealing the dominance of American AMD-based systems amid a lack of new entries from China, as well as the performance of supercomputers used by AI giants such as xAI and OpenAI.
The latest update to the global high-performance computing rankings places the AMD Instinct MI300A-based El Capitan at the forefront with Rmax performance of 1.7 FP64 ExaFLOPS, followed by the AMD-powered Frontier (1.353 ExaFLOPS) and Intel-based Aurora (1.012 ExaFLOPS) as the top three exascale-class systems, all of which are operated by U.S. Department of Energy laboratories.
