WebWatch: AMD Hammer: one hot chip?

AMD A WHILE BACK, AMD gave a ballpark figure as to the power requirements of the Hammer. The figure seems fairly respectable, a 100 million transistor chip operating at a moderate 70 watts. Whether this low power figure is due to a comparatively low clock speed or the silicon on insulator (SOI) process is difficult to tell. Suffice to say that, for a chip that is supposed to be PR 3400+, that's a very low power requirement. The story of power gets deeper, though. Start counting those transistors. A Sledgehammer (Opteron) with 1MB of cache will have 100 million of the little blighters. Now start thinking about the Clawhammer (Athlon 64). The base model only has a 256K cache. That knocks down the transistor count by more than a third. Realistically, we're talking a 60-65 million transistor chip.
