Mobile Athlon 64 versus Intel Centrino

Archived from groups: comp.sys.laptops (More info?)

I have found iteresting laptop on Hp site, it has Athlon 64 3000+ processor.
I wanted to find out if it is mobile version or mobile so I called Hp USA
and they told me that it has Power Now technology so it must be mobile
version. Is it true that if Amd has Power Now then it is mobile version?
Another issue that concerns me is how AMD Athlon 3000+ is comparable with
Centrino platform /Pentium M/, I put emphasis on power consumption. Is Power
Now as good as Centrino's power management? What is power consumption in
Athlon 64 Mobile?
Thanks for answer.
