When it comes to exaflops it is the floppiest El Capitan has been ranked as the most powerful supercomputer in the world. It boasts a benchmark performance of 1.742 exaflops, or 1.742 quintillion calculations per second,

The supercomputer, housed at Lawrence Livermore National Laboratory, achieves 1.742 exaFLOPs. China's machines could be even faster, but it's not sharing details publicly.

El Capitan’s data processing abilities represent a major advancement in scientific research, particularly for managing the nuclear stockpile.

El Capitan was built by HPE for the National Nuclear Security Administration (NNSA) at the Lawrence Livermore National Laboratory (LLNL) to simulate nuclear weapons tests. It is powered by AMD instinct MI300A APUs and is not only the fastest but also in the top 20 of the greenest computers too.

El Capitan has more than 11 million combined CPU and GPU cores based on AMD 4th-gen EPYC processors. These 24-core processors are rated at 1.8GHz each and have AMD Instinct M1300A APUs. It's also relatively efficient, as such systems go, squeezing out an estimated 58.89 Gigaflops per watt.

A supercomputer housed at the Lawrence Livermore National Laboratory (LLNL) in Livermore has officially been crowned as the world’s fastest. The computer, known as “El Capitan,” is a collaboration between LLNL,

Newcomer El Capitan unseated five-time No. 1 system Frontier and is now the third exascale machine in the TOP500 supercomputer rankings.
