<There is nothing in Hammer that makes it a really good mobile chip>

There was a post a few days ago on the specs for a Hammer DC-DC convertor chip and I posted a response to it. The specs on the chips say that the Hammer will use no more than 40 amps and Vcc cannot be set higher than 1.55 volts. From that its reasonable to conclude that the largest cache Opteron (1M or 2M) will not use more than 1.4 volts x 40A = 56 watts.

Normally they would design such a chip to handle not only the introductory power levels, but also the highest power consumption expected over the lifetime of the chip. In other words, the power consumtion of the fastest Clawhammer at introduction had better be considerably less than 50 watts, or these DC-DC chips will soon be obsolete. A 1.3v Clawhammer running at 2/3 speed might reasonably be expected to draw no more than 30W, putting it into the high power notebook category.
