Power Draw on CPU's

[cheez]

I currently have an Intel Conroe E6600 CPU in my system running at default clock. How much power does this draw compared to the latest Intel chips such as i7 and i5? Just trying to get an idea how my chip stacks against the latest brothers.

:ninja:

Lemme know. thanks!

Not enough to warrant a new system unless...

A. You need more performance
B. You are running the machine 24/7 for extremely prolonged lengths of time

That said I would imagine the biggest difference in power draw would be at idle with your chip losing by a fair margin. Was there a particular scenario you were wondering about or were you just interested generally?

I was just wondering if anyone has info on power consumption between the latest CPU i5 or i7 core and a 7 year old Intel chip Conroe (2.4ghz).

Yes my chip will run at anywhere from 1% to 20% CPU utilization.

thanks,

Not sure if this is relevant to you, but the biggest upside power draw-wise might be the igpu and the fact that you dont need a discrete gpu. That could easily shave off 30 watts or more idle.

I currently get around 60W at the wall with a dual-core Conroe-based Xeon and a low end GPU (Radeon 6450). From reviews I've seen, a similarly configured i3 with IGP idles at around 40W, so you're looking at ~20W difference.

In low usage situations like yours, the difference is probably on the order of 5-10 watts, in favor of the new stuff. A lot of these savings would be from the other components integrated on the CPU, though.

Thanks for the info guys. This gives me good ballpark figure.

I don't have numbers for you cheez (still trying to find my start button, lol) but the room I ran more Core2 quad in is noticeably cooler with the system in my sig.

buy a kill a watt. My laptop can run as low as 12 watts, your cpu isn't the drain. It's miniscule compared to the monitor, hd, etc.

I agree, although having to use a discrete GPU is going to be pushing up your power usage a lot more than a CPU with IGP.

Another component to look at is the PSU, if it isn't high efficiency (keeping in mind that psu's tend to have worse efficiency at 25%< and 75%> then you can be wasting power there as well. The other component that can suck juice like crazy if it is an older model is the monitor, technology has come on leaps and bounds the last few years and new "green" monitors can use 10% of what some of the old models did.

All of these power saving get compounded if you live somewhere hot and are using AC to cool the house.
