Synthetic RGBB magnitudes are generated with the most recent theoreticalstellar evolution models computed with the Dartmouth Stellar Evolution Program(DSEP) code. They are compared to the observational work of Nataf et al., whopresent RGBB magnitudes for 72 globular clusters. A DSEP model using a chemicalcomposition with enhanced $\alpha$ capture [$\alpha$/Fe] $ =+0.4$ and an age of13 Gyr shows agreement with observations over metallicities ranging from [Fe/H]= $0$ to [Fe/H] $\approx-1.5$, with discrepancy emerging at lowermetallicities.
