I don't think the absolute temperature is directly related to the wattage. Heat transport also factors into it. You could always keep the chip cooled with active heat pumps or carefully applied liquid nitrogen.
It's just impractical, especially getting everything cooled equally in the presence of hot/cold spots.
- dom0 10y agoHeat resistance is approximately a given (surface area), so wattage depends on the permissible temperature difference between the two items (die and heatspreader). If you run hotter, you can dump more power into it. Temperature is ultimately limited by sped up diffusion of doping and such, temperature limits in surrounding materials (eg epoxy-based chip carriers or epoxy-based case material), and reduced performance due to increasing leakage currents.
