Very Interesting Article on System/CPU Power Usage and Performance

[CupCak3]

This article seems pretty interesting from what I've seen so far though I haven't had the time to read it thoroughly. Could come in handy if you're taking into account energy costs like me when building new DC machines.


Low Power and Energy-Efficient CPUs from Intel and AMD

Thoughts?

Interesting thanx, gonna read it now..

Since DC computers usually run at 100%, the energy used at "idle" is not of any interest to me.

During the current (and most likely future) times of high energy costs, the $ per DC work unit would interesting. I don't know what tool we could use that would be the most accurate across the DC realm but for BOINC it would seem you could divide a system's RAC by the cost of operation to determine the most $ efficient DC system. Has anyone already done this?

Can't we just build wind & solar farms to power more rigs?

Btw I've got a mains power meter if you want me to run any tests on my ageing XPM rig? (it uses 185w at 100% load inccidently!)

I just got a kill-a-watt so i'm going to start testing my mahcines to see what I come up with. Most of mine are comprimes of barton's and thoroughbred's w/ a couple palermos and a some sempron. But i did just buy a 65W 3800+ which i'm going to run on a Tforece. It'll be intesteing to see how it fair's w/ their numbers.

whoooosaaaa.... whoooooosaaaaa.....

I shouldn't have read that article. It was a very interesting read, particularly the cost per work done on the AM2 (ADD) 3800+, but now I want a new AM2 dual core system even more than I wanted it before, and I still can't afford to build a new system any time soon...

Well if you want the SSF EE cpu, you're in luck b/c they really aren't available for retail yet even though AMD did a paper release several months ago. But the 65W EE version is ready for enjoyment

Nice new rig

Btw my XPM 2500 rig runs at 2.5GHz ,has 2xHDDs ,FDD,1xDVDRW,1GB RAM ,Radeaon 9700 Pro,1xNIC (+1 onboard) ,Antec TPII 430 PSU,2x80mm fans & a 92mm fan.

My 2nd rig ,a S754 Sempron 3100 @2.5GHz ,has 1xHDD,1xCDRW,FDD,GF4 Ti4200,512MB RAM ,ColoursIT 500w PSU,1xNIC ,1x120mm ,1x80mm fan & CPU fan(70mm?).
This rig draws just 120w running DPAD (or SETI),so it draws about 1/3 less power & its about 15% faster at DPAD too! (I'll be swapping mbrds & CPUs over at some point ).
I'm going to get a better HSF for this rig & I'm hoping I'll get a slightly better overclock
