High-p<sub>t</sub> hadrons are produced in large-momentum transfer parton scatterings in p + p and Au + Au collisions at RHIC. In Au + Au collisions, the production is modified compared to p + p collisions by interactions of the hard-scattered partons with the hot and dense medium. Relevant results on high-p<sub>t</sub> hadron spectra, elliptic flow and azimuthal di-hadron correlations in Au + Au collisions at √s<sub>NN</sub> 62.4 GeV are presented and compared to available results at 200 GeV. Qualitatively similar suppression patterns are observed at both energies.
