The dynamics of partons in ultra-relativistic [sup 197]Au+[sup 197]Au collisions in the future collider experiments at RHIC and LHC during the first 3 fm/c are simulated in full six-dimensional phase-space within a parton cascade model to compute the entropy production and the space-time dependent energy densities, temperatures, etc., in the central collision region. The partons' evolution from pre-equilibrium towards the formation of a thermalized quark-gluon plasma is quantitatively analyzed resulting in predictions for the energy densities [epsilon][congruent]15[minus]31 GeV fm[sup [minus]3] and associated temperatures [ital T][congruent]295[minus]345 MeV at [radical][ital s] = 200 [minus] 6300 A GeV. The multiplicity of final points from the plasma is estimated from the amount of entropy produced, yielding a huge [ital dN][sup ([pi])]/[ital dy][congruent]1900[minus]3400. An equation of state is extracted together with initial conditions for the further hydrodynamical space-time evolution of the matter.
