TOP500 List - November 2023

R_max and R_peak values are in PFlop/s. For more details about other fields, check the TOP500 description.

R_peak values are calculated using the advertised clock rate of the CPU. For the efficiency of the systems you should take into account the Turbo CPU clock rate where it applies.
