Quad Power Consumption Graph

[21stHermit]

Here's a Quad Power Consumption Graph done by X-bit which shows how much more efficient 45nm is compared to 65nm Quads.

This bodes well for all of the 45nm CPU's.

 

[wwswimming]

Power Consumption with 4 Load Threads -
Phenom ~ 131 watts
Q6600 ~ 79 watts
Q9450 ~ 58 joules/second

8 watts idle power consumption for the Q9450. DAMN, thumbs up !

if we could only convince PG&E to sell Quad Cores
below cost, the same way they're doing with
compact fluorescents. ($1 for quantity 2, 23 watt,
1680 lumen light bulbs.)

"We measured the current going through the processor voltage regulator circuitry, thus estimating the power consumption of the CPUs themselves"

This isn't new news. Hopefully AMD can get their shit together, and eventually release a competing product.

I know that this is off the topic, but what is wrong with Lasik wwswimming? I had Lasik done several years ago, and I couldn't be more pleased. I have better than 20/20 vision... 😕

These numbers can also be used in relationship to heat produced by the chip.

whats funny is when you overclock to 1.4 you about double these values in heat output.

Bring the OC up to near 1.45 the value climbs to ~ 200-215

Drag the numbers up more to 1.5 where everything is thinkn its okey to run a quad on air. That power draw number goes up to almost 300.

Now how are you people suposed to cool 300W of heat on air?

Said Otellini to Barret as he kicked the ex-Intel CEO in the ass and shoved a Netburst up there for good measure...

I don't overvolt my CPU's because I use them for 24/7 365 operation. 😉

imo i believe a 5% over volt would be safe for 24/7 365 usage provided you have acceptable temperatures. my absolute limit for overvolting and non 24/7 365 usage would be 10%.

If you don't overvolt then you are likely to be good for 24/7 365x10 operation (i.e. 10 years or longer continuous operation).

For those of us who have no intention to be running today's relics in 3 years time (where will you be in 2011?) we can live with 24/7 365x3 operation with some elevated Vcore along the way.

mostly fud. there was an off-topic discussion here

QFT!!!

Even more reason for me to get a Q9450.

Wow.. wonder what that works out to over a year in power costs.. I leave my tower on 24/7 OUCH!

About the same as leaving a couple 100W lightbulbs on all the time. (maybe 25 cents a day)

Peanuts compared to what your hotwater tank is costing you. Also peanuts compared to what your AC or heating bills are.

Wow.. wonder what that works out to over a year in power costs.. I leave my tower on 24/7 OUCH!

We pay $0.07/kWh for electricity. For a ~125W computer idling 24/7 in my area (my computer idles at about 115W measured at the wall), one would pay $0.21/day which is $6.30 per month. For a quad-core CPU running all four cores on something like Folding@Home 24/7 in a a place like southern California where rates are more like $0.13/kWh, one could expect to pay something closer to $18 per month.

For what it's worth, for comparison, we pay ~$22/month for just the hot water heater (natural gas, Xcel energy, northern Colorado).

If I left my computer on 24/7, it would use approximately 10% of the total electricity that we use in one month (we average about 750kWh per month - and yeah, that's a bit below the average - it goes up a bit in the summer, but we don't need or use the AC much).

* Thanks to engineer for correcting my math. Fixed. *

speaking of power consumption, why do we use kwh instead of joules (or megajoules)? after unit conversion, it's all joules

 

[pm]

Because the electric company charges me in kWh? 🙂 And that's what I see when I look at my bill...

it's sort of like talking about a car accident over and
over. there's a thread in Health & Fitness about it.

We pay $0.07/kWh for electricity. For a ~125W computer idling 24/7 in my area (my computer idles at about 115W measured at the wall), one would pay $0.42/day which is $6.30 per month.

125W would take 8 hours to equal a killowatt. You would get 3 kWh throughout the day so you would pay $0.21 per day, not $0.42 per day???

Is my math fuzzy or yours? 😉

I have been running my QX9650 + 8800 ultra and see almost 450w from the wall while gaming.

Overvolting these chips increases usage rapidly.

Let's round it up tp 500W...or 0.5 KWh...still is only costing you about 10 pennies an hour while you play even if you live in HW and pay $0.20/KWh.

Crunching is considerably cheaper as your video card is idling.

My overclocked 3.3GHz G0's draw 225Watts from the wall when processing small FFT's...which is about as close to peak CPU power usage as I can get them.

For my actual application of interest that I do run 24/7 with all cores loaded I see about 190W pulled from the wall. About the same as a couple 100W light bulbs left on all the time.

 

[The-Noid]

I wasn't complaining. I run all my computers 24/7 for crunching just stating that you can ramp up cpu draw considerably when overvolting.

I didn't take it that way. I was replying to your post with the intention of "merely expounding on the conversation that we are talking about measly pennies here".

I'm pedantic like that some times. Just ignore it if it gets overly annoying.

I wrote it for a 250W computer and then decided that was too high, changed it to 125W thinking that was more realistic. When I changed it, I changed 125W and the final answer - $6.30 ($0.21/day * 30 days) but not the intermediate one.

Thanks for the correction.

As Idontcare mentioned, this includes the video card. I pulled this power-hungry monster from my calcs because I couldn't picture someone using their videocard 24/7.... although some people I know who play WoW might come close. 🙂

Let's round it up tp 500W...or 0.5 KWh...still is only costing you about 10 pennies an hour while you play even if you live in HW and pay $0.20/KWh.

"HW" is Hollywood? Or Hawaii? They seriously pay $0.20/kWh? Wow. At $4.50/W, solar starts to look like a viable option in either of those places with the Fed tax credit.
