Mani,

As is the fan and the junction between the die and the heat sink.

Hammer will have integrated heat spreader. What are the advantages, and can it be quantified?

The way I see it, integrated heat spreader can:
- protect the core from mechanical damage, as it is not exposed
- larger area, higher heat dissipation, if heat sink gets detached, the mass and the area of the heatsink give the CPU more time to do what it needs to do gracefully
- larger contact area with heatsink, helps conductivity. But isn't there some loss in conductivity from the silicon to integrated heat spreader that offests it?
