Q6600 vs E6850 electricity costs???

[fretman]

The E6850 is 65w. The Q6600 is 105w.

On average use about 3 hours per day what is the difference is electricy costs? Thanks.

That's the amount of heat these models produce, the Q6600 also has a 95W model with the newer G0 stepping.

In terms of power costs it's not easy to say but what is certain is that the power used to performance ratio will be in Q6600 favor. Other than that it's not just a case of 2 Vs 4 cores, these models work at very different frequencies (2.4 and 3GHz).

Also don't forget even the quad cores starting from B3 stepping have Intel SpeedStep technology so unless you turn it off in the BIOS, it will lower the chip to 1.6GHz when idle hence consume less power and produce less heat.

It makes most sense to buy the Q6600, Intel knows this and that's why it's positioned it as a price were many can afford and be extra happy with the added performance. You can always overclock, 3.6GHz from a G0 Q6600 is within reach for mind blowing performance.

For normal use, the E6850 will use less power because even Speedstep-enabled idle cores consume power, at least with the current setup.

Thanks for the help....I'm still flipping back and forth between the E6850 and Q6600.

Go the Q6600 - at idle, the difference in power consumption will be negligible. If you get the G0 (95W), the power difference will be 30W (at full load). That's half of one standard light globe. Replace a 60W incandescent globe with a 15W fluoro, and enjoy the power of a quad-core with feeling guilty.

Just for interest:
30W x 3hrs x 365days = 32.85kWh per year. Power costs somewhere around $0.10/kWh, depending on where you live. So it'll cost you about $3.28/year.

Good analysis. I'll go for the Q6600. However, the store will be getting a shipment in next week. I'm not sure if they'll be the G0 or the B3?

why not go with CLUBIT.com since that's all they're shipping now?

 

[fretman]

I like the store I'm ordering from so I'll stick with them. I just hope it's the G0 batch.

WHAT?? I like newegg but they were overpricing their cpus so I got mine from xtreme gear. There are a LOT of reputable online retailers, and clubit is one of them. there is absolutely no reason to settle for a chance at the b3 when the g0 has such tangible benefits. One you have the cpu then you won't remember where you got it, anyway.

 

[fretman]

Correct....but I'm not putting the system together...the store is. If I knew how to put one together I would. However, if I buy the rest of the components from the store and got the CPU from another place and brought it to them I'm not sure if they would put the system together for me.

Worst case: you live in Europe and you always use you PC at full power during those three hours. Feeding the CPU will cost per year:

3h x 0.065 kW x 365 days x 0.30 ? = 21.35 ?
3h x 0.105 kW x 365 days x 0.30 ? = 34.49 ?

So not much to worry about with so little use.

Why is it that everyone is taking the TDP values and using them as an indicator of how much power these CPU's consume?

That's the amount of heat they produce on average, not the amount of power consumed, both measures in Watts.

Looks like the store will be getting the G0 batch of Q6600's. Thanks.

In any semiconductor, most of the energy put into it will be converted into heat, while a very small amount goes back into the mobo. Since the same amount of power will go back into the mobo for both of these CPU's, then the difference in power draw will be the same as the difference in heat, which is 30W.

OP: If you can, wait until you can be sure you're getting a G0. They're better all-round, and the only disadvantage is waiting a week or two...

Wrong, I have had my B3 for like 6 weeks or so, and The G0's are just now starting to appear, and not enough feedback on HOW much better they are (granted it looks very promising)

Because they're the same thing?

If there is a difference between power draw and heat output, where do you suggest the missing energy goes?

 

[hans007]

i would get the quad.

in fact if you are even seriously debating this you probably dont need the quad and probably only really need an e6550. don't buy something just because its in the "price range you feel like spending"

Compare the Q6700 and E6750, your only saving 9W in idle mode, though the load difference if all 4 cores are used vs 2 is 50W, but if your only using Single Threaded workloads then the difference wouldn't approach that at all.

And GForce100 is right TDP only gives you a indicator of what the entire lineup draws at maximum, but not what the processor actual disappates you need to view actual results to get those values.

Since the Q6700 is 95W as well, and the E6850 has a TDP of 65W, but the actual difference is 45W. SO E6850 is further below it's TDP then the Q6700 is.

You also got to remember that the E6850 can only drop down to 2.0GHZ at idle while the Q6600 can drop down to 1.6GHZ at idle, so like show the difference isn't that great.

 

[theprodigalrebel]

I believe using something like RM Clock, you can reduce idle speed/vcore even more? It's been a while so I may not be entirely accurate about the program's features.

 

[IvanAndreevich]

Just get the G0 stepping and forget about it. Under gaming load Q6600 won't consumer more than the E6850. The only way to get it to consume 95W is to render / run quad Prime95 on it. But in that case it will still have better performance-per-watt.
