Price vs. Performance vs. Watt vs. GHz

I thought this (http://www.xbitlabs.com/articles/cpu/display/core2duo-shootout_13.html) aspect of the X-bit article very interesting. However, power consumption (http://www.xbitlabs.com/articles/cpu/display/core2duo-shootout_11.html) appears to be a tad bit less then what I've seen here.

The X6800 uses less power than any other chip when idle?
Is that right? Pretty impressive if so. an anyone find a drawback for Conroe apart from not a lot of motherboards to choose from at this early stage? Everything I've been reading for months now just keeps confirming thatit's getting better and better.

Looks more like a rounding in the margin of error.

[Mikesnav]

Why is the E6300/6400 so high in idle?

i thought they had EIST as well.

[Haltech]

That cant be right, whatsoever. Even idle wattage isnt that low, at least not in a full running system its not. How did they come up with those numbers?

[FunkyRider]

Allendales' don't have EIST, goes from 7x to 6x is meaningless

I don't see what the big deal is...

Unless all of you are planning to make a passivly cooled PC heat with Conroe at idle is a non-issue. Same goes for AMD really. Now temps when OC'ed and over-volted climb pretty quick and that is something to worry about. Only people really should worry about idle temps and power draw are those who are running a rack-mount with dozens or even hundreds of CPUs in 1/2U cases, then it begins to add up and effect TCO.

I can live with temps.. My interest is total wattage consumed at full load. Im going to have a farm of these for DC Projects.

Does anyone know how to get your total wattage from a system at full load?

Not really. I just like efficiency, and I think others here do too.

You can buy power consumption meters, that you have to put between your PSU and wall-outlet. This is the total consumption, with the power that is wasted in the PSU as it's efficiency is never more than 70-80% in the best case.

[Danger30Q]

A good power consumption meter is called the Kill-A-Watt made by P3 International. They can be found on eBay.

[Gun_Strife]

wow just checked on the Kill-A-Watt and that looks great and can be had for $26, think ill pick one up ty Danger30Q
i wanna test it with my current rig and then my conroe rig when i get it

[Eastcoasthandle]

post your results.

Lower power consumption can be good for OC, more headroom before the heat becomes unmanagable. Ok, i know that isnt entirely true for AMD X2, preslers overclocks better even if they are powerhungy beasts (i mean, not to the same performance level but higher compared to original clock). Will be fun to see this again when they add X2 EE to the charts, and thats what the AMD-fans will be interested in, unless they changed their minds and power consumption was only important for Prescott/smithfield/presler... Time will show but i think AMD fanboys are not as interested in power consumption now as they pretended to be before Conroe was revealed :) History has shown the same happening before, for example Athlon XP's heat was a problem only for some of the Intel fanboys, and Prescott heat was a big problem for AMD fanboys.

Nice and all if you appreciate it, just be aware that if/when you OC one of the first things to go is that efficiency (heat and power scale in a non-linear fashion), so still doesn't make a whole lot of sense to me to focus on it here as this site is OC-centric.

You mean me OCing my Video card, RAM, chipset and cpu negates all the 'power saving' technologies? /joke


good thing power is included in the rent :toast:

If you put load on em' sure. Stuff like clockspeed scaling and under volting can still work to lower power/heat but only if you're putting little to no load on the machine. If you're that concerned about power/heat you'll turn the machine off if you're not using it, that'll save way more power than any sort of power saving tech.

damn good point :clap: :clap:
