Abstract: We consider a class of seven-dimensional $\mathcal{N}=1$ supersymmetric orbifold GUTs in which the standard model (SM) gauge couplings and one of the Yukawa couplings (top quark, bottom quark or tau lepton) are unified, without low-energy supersymmetry, at ${M}_{\mathrm{GUT}}\ensuremath{\simeq}4\ifmmode\times\else\texttimes\fi{}{10}^{16}\text{ }\text{ }\mathrm{GeV}$. With gauge-top quark Yukawa coupling unification the SM Higgs boson mass is estimated to be $135\ifmmode\pm\else\textpm\fi{}6\text{ }\text{ }\mathrm{GeV}$, which increases to $144\ifmmode\pm\else\textpm\fi{}4\text{ }\text{ }\mathrm{GeV}$ for gauge-bottom quark (or gauge-tau lepton) Yukawa coupling unification.
