Need some info, help!

[axispr]

Right now I'm taking a Computer Architecture class. My first assignment was to do a comparison between the specs of some mobile processors. I almost have all my info, but can't seem to find power consumption and cost of some of the chips.

Here are the chips I'm comparing:
Athlon XP-M
Athlon 64 M
Pentium4 M
Pentium M
Celeron M
Transmeta Efficeon
Transmeta Crusoe
Via C3 Mobile

Any help finding the cost and power consumption of these chips would be appreciated...

Thanks!!!
