  Measurements of identified particle production with the PHENIX experiment at
RHIC have reached a mature state, where a multitude of nuclear systems at
different colliding energies have been studied. The discovery configurations of
$\sqrt{s_{NN}}$ = 130 and 200 GeV Au+Au collisions have now been supplemented
by additional Au+Au and Cu+Cu configurations at various energies, along with
baseline p+p and d+Au runs at $\sqrt{s_{NN}}$ = 200 GeV. In this work we
present a systematic study of the Cronin effect in d+Au collisions and recent
results from p+p collisions. We then proceed to make a critical comparison of
pion, kaon and proton production in heavy ion and baseline systems, and discuss
the observed nuclear effects on hadron production.
