High energy density (HED) laser, soft X-ray black body (BB), light, and 20 km/s mechanical impact interactions in warm dense matter (WDM) regimes are compared at equivalent intensities. Different transport mechanisms induce different equations of state and material responses for HED plasma driven ablation interactions at ~100's GPa and ~105 K with energy densities more than sufficient for target vaporization. These HED interactions characterize WDM at temperatures of ~0.1-30 eV and densities of ~10-3-10 g/cm3 the upper ranges, 0.5-30 eV and 0.5-10 g/cm3, are thought to exist in giant planetary cores and HED planar shock waves. Plasma region pressure (P) and temperature (T) generated by intensities of ~1015-1022 W/m2 depend on target properties and irradiation wavelength or impact velocity. At 6×1015 W/m2, P and T vary from 20 MPa to 1.2 TPa and 17-49 eV effecting P/T gradients, BB peak wavelengths, ablation and hydrodynamic regions of solid targets. Momentum coupling varies from 3.3×10-9 to 10-4 s/m.
