I'd expect the two die to be thermally coupled though. It's difficult for them not to be. There will be conduction through the package substrate's power and ground planes, and (more importantly) through the heat pipe connecting the two die to the HSF. So I wouldn't be surprised if the eDRAM die Tj tracks the CPU+GPU Tj despite the disparity in W/mm^2.
