Hardware advice wanted


Because of recent circumstances, I’m looking for at least 1 ‘new’ laptop. Is there anyone using DragonFly on a laptop? (Other than those mentioned here.)

Along the same lines, has anyone put together a server recently with a focus on low power usage?

    I’ve been researching power consumption lately, mostly on the AMD side of things — which has a clear lead on the desktop/server chips. [Disclaimer: AMD shareholder. :)]

    One odd thing: Semprons appear to have a higher performance-per-watt than Athlon64s; with modern processes, large cache can apparently suck a lot of power vs. the execution units. From various benchmarks, I get the impression a Socket 939 Sempron 3400+ is at least on par with the low (3000+?) end of the A64 range; remember, the Sempron fake-clock numbers are supposed to compare to a Duron, while the Athlon fake-clock numbers compare to previous Athlons. They also apparently have a nice low consumption at idle — something like 9W for some particular model, though the A64s are only a little further into the double-digits — which was an efficiency concern for me replacing office desktops that spend a lot of time doing nothing.

    If you want something dual-core, there’s a thermal sweet spot somewhere around the 3800+ x2 and, I think, maybe the 4200+ or one particular lower-numbered 4n00+.
    (Using http://www.hothardware.com/viewarticle.aspx?articleid=710&cid=1 for a quick reference here.)

    If you absolutely don’t give a shake about performance, apparently the new Geodes with the funny part numbers pop into Socket A. Of course, then your northbridge might have a louder fan than the CPU. No idea how this compares price or performance-wise vs. going EPIA.
