The suppression of hadrons with large transverse momentum ( p T ) in central Au+Au collisions at compared to a binary scaled p+p reference is one of the major discoveries at RHIC. To understand the nature of this suppression PHENIX has performed detailed studies of the energy and system-size dependence of the suppression pattern, including the first RHIC measurement near SPS energies. An additional source of information is provided by direct photons. Since they escape the medium basically unaffected, they can provide a high- p T baseline for hard-scattering processes. An overview of hadron production at high p T in different colliding systems and at energies from will be given. In addition, the latest direct photon measurements by the PHENIX experiment shall be discussed.
