The 59th edition of the TOP500 revealed the Frontier system to be the first true exascale machine with an HPL score of 1.102 Exaflop/s.
The No. 1 spot is now held by the Frontier system at Oak Ridge National Laboratory (ORNL) in the United States. Based on the latest HPE Cray EX235a architecture and equipped with AMD EPYC 64C 2-GHz processors, the system has 8,730,112 total cores, a power efficiency rating of 52.23 gigaflops/watt, and relies on Gigabit Ethernet for data transfer.
However, a recent development to the Frontier system has allowed the machine to surpass the 1 exaflop barrier. With an exact HPL score of 1.102 Exaflop/s, Frontier is not only the most powerful supercomputer to ever exist — it's also the first true exascale machine.
