1kW TDP chips need LESS cooling?

  Yes, Rubin reportedly can deal with running significantly hotter. That makes radiating a much more practical approach to cooling it.

    I see what you’re saying - higher design temp radiates better despite more energy overall to dissipate.

Yes, running hotter will cause more energy to be radiated. but These parts are not at all designed to radiate heat - just look at the surface area of the package with respect to the amount of power they consume.

        I think OP was saying hotter part -> hotter radiator attached to the part, not that the part itself will radiate significantly.
