    Hey all, I got a quick question...Does all current AMD CPUs have the power (battery) saving technology?

    TIA.

    If you are talking about the mobile CPU's, yes.

    yup they have better power saving capabilities as compared to intels chips but ultimately you will be sacrificing on performance

    Yeah, I meant mobile CPU's.

    Awesome...when AMD cpu comes to Dell, I will get the Sempron, or cheapest as possible cpu durring that time. I dont care about performance, my current CPU is more then enough. :)

    yeah, my desktop Athlon 64 has Cool n Quiet, basically a crippled version of the laptop PowerNow!

    Cool n quite refers to desktop CPUs, while Power Now was introduced for mobile CPUs. I'm not aware of the differences, if any.

    AMD mobile processors are amazing for undervolting. You'll really save some power if you want to. That's pretty much the only thing I like better about my Athlon 3200+ compared to my T2400. You can't undervolt the T2400 any further than speedstep sets it. I brought the voltage on my 3200+ down from 1.35V to .85V. Big difference. Battery now lasts a little over 3 hours instead of an hour and a half. Also, the fan never comes on high anymore(even with 6 hours of Prime 95 torture test) and the fan exhaust is always cool. Never even warm.

    Also, I notice you have a Celeron. I have a 2.8ghz celly laying around, from my old HP ZE5730. Those things really suck for battery life, as I'm sure you already know. Intel cut the powermanagement from them, so they never scale the speed or voltage.

    Oh, and mobile AMD processors own. I suppose the Core Duo has a few advantages over AMD mobiles now, but the Turion and Mobile Athlon 64 will crush any pre-Core Duo Intel CPU in performance. The Pentium M might get slightly better battery life, but if you undervolt your Amd processor you should be able to beat it in that respect. It's not by any means far behind in battery life.

    I think PowerNow might be able to scale further down in clock speed and frequency. Not sure though, but if anything, that's the only difference. So I wouldnt call it "crippled" either.
