Comparison of the TNG-Cluster sample introduced here to other simulated cluster ensembles. For each simulation we contrast the numerical resolution, in terms of gas/baryonic mass resolution (y-axis), versus the number of simulated massive halos with M_200c ≥ 10¹⁵ M_⊙ (x-axis). We include only cosmological hydrodynamical simulations of galaxies, both uniform boxes (circles) and zoom-in suites (diamonds). The vast majority of these simulations include models for both stellar and supermassive black hole feedback physics, although they vary in many key aspects (see text for details).
