AMD releashed their new low power CPUs yesterday.
The original Opterons run at 80W.
The *48s run at 89W.
P4E runs above 100W.
Opteron HE runs at 55W! (*46)
Opteron EE runs at 30W! (*40)
While they do not have 2.2GHz like the rest, they will soon upgrade to those speeds.
Price Comparison
*48s = HE *46s = EE *40s.
The EEs may be very expensive, but it uses very little energy, which means. very little heat.
Good job AMD for making such a cool and energy efficient CPU.

PS: These Low Power Opterons are similar to the Mobiles in which the DTRs are the Regulars and the Mobiles are the Low Powers.

It dosent matter about power.. If you have atleast a 400 Wat Power supply, you are good.. No need for this at all

You are looking at this from the wrong perspective. Less power means less heat.
Uses:
Servers who don't want large energy bill
Companies who want cool CPUs
Overclockers who want to OC 20GHz (exageration, but it does offer better overclocking)
