HPCG - June 2025

The TOP500 list has incorporated the High-Performance Conjugate Gradient (HPCG) benchmark results, which provide an alternative metric for assessing supercomputer performance. This score is meant to complement the HPL measurement to give a fuller understanding of the machine.

  • El Capitan is the new leader on the HPCG benchmark with 17.4 HPCG-PFlop/s. 
  • Supercomputer Fugaku, the long-time leader, is now in second position with 16 HPCG-PFlop/s. 
  • The DOE system Frontier at ORNL remains in the third position with 14.05 HPCG-PFlop/s. 
  • The Aurora system is now in fourth position with 5.6 HPCG-PFlop/s.
