Power consumption does'nt matter?

Power consumption does'nt matter? I hear people say so, so lets look at the numbers.

You better have a look at your power bill and calculate 95W (X2-4800) vs 179W (840XE) 24/7 over a month. I pay 14 cents per Kwh

84W * 24 * 30 * = 60KWh/month you are losing by buying Hot hot hot P4 over a64 eq. 60 * 14 cents is $8.40 a month!!! Or $100.80 a year you're losing out on running Pentium dual!!

Not to mention I live in the desert and have to pay more for A/C 8 months a year because added heat the prescott will introduce into my home.

That is assuming you are running 24 hours a day of course. I run 24hours a day for Folding@Home and I can't wait to have my X2 4400+ watercooled running at 2800 two concurrent folds.

Edit: The power consumption of the Pentium Dualcores to me is unbelievable. People talk about the less expensive Pentium D dualcore but don't take into account 80 dollars a year (160 dollars per 2 years) the diffeence between them and the X2's. Of course the X2's dominate all but the 840EE in performance to boot. Intel is lucky AMD doesn't have Fab36 up and running with cheaper dualcore or they would have an even bigger headache.
 
Say you Overclock your pentium dually's..thinking of course you got a "deal" with the $270 820 right... OK

OC 820 to 3.8Ghz (assuming you got water or phase change to nessesitate proper temps). At this point you have two 670's which use 162W a piece, meaning you're using 324W on just processor!!!

That's $230 a year premium you're paying!!! Easily paying for the 4200/4400 clocked to 95W 4800 levels...

Deal for 820? I don't think so

LOL. I wonder what the power draw is for the overclocked AMD X2's. Say 2800. That would be interesting. I agree with you, the Intel chips use so much wattage that people forget to take into account the extra juice costs for the performance (or lack of) they are getting down the road.

Maybe you could help answer my psu question for my X2 that I am getting I posted this question about half hour ago for my upcoming watercooled X2
 
2800Mhz X2?

140W is my guess on 512 chip and 155W on 1024 chip depending on Vcore ..

AMD starts leaking like crazy after 2600Mhz... Intel after 3100Mhz on 90nm
 
The power consumption of X2 are still too high imo, the next generation of dual-cores has to go down to 60Watt. And dont forget quadcores, i wont buy me a quad with 250Watt...

I doubt they will release quad+ core processors on the current 90nm process. They'll likely go to 65nm or lower which, for AMD 😉, means you'll likely see less or the same power consumption on quad+ core parts that you see now on their dual core parts. Intel will likely keep rising in power consumption on Netburst. 😱
 
Intel has Speed Step which is the same as Cool & Quiet

One thing to also consider in power consumption for your pc is the efficiency of your psu. An OCZ 520w Powerstream is only 63% efficient at load compared to a Seasonic S12 which is 80% efficient. Just something to consider.
 
I have been saying the same thing for months, and nobody listens to me. Me electic bill is about $100 a month for 6 (now 7 at the price of 6) computers 24/7, and everything else, including AC. If I had 820 dual-cores, it would double or triple (AC) to $200 or $300 a month. Businesses will see a big savings.

Too high!?!? What do you run a Via C3 Eden and anything above that is too high??

Tell me you are joking.

Excellent thread Zebo. I was wondering that myself.

That is an eye opener! I am going to miss the dorms and running everything all the time (AC w/windows open to have better "circulation", etc...) w/out worrying about the costs... boo for moving on and getting older... 😛

Uhh.. they did. But The P3s were better performers back then and the athlons were widely regarded as crappier chips. It wasn't until K7 and P4s were released that AMD began to overpower (and underprice) Intel...

They were. But not only that 30W differential is nothing, a VCR or a clock radio or a DVD player. Not all three of them together (84W) like the difference here! And not fuggin 324W if you start overclocking!! That's what my 220 gallon commercial air compressor uses in my garage with it's 10HP electric motor!

Exceelent point so if you're using a PowerStream that overclcoked 820D is using 528W from outlet... do the math with y'alls electric bill.

It is a whole helluva lot higher efficiency than that.

The 470 Watt never makes it below 70. At peak output you are looking at 78%. A full 15% higher than what you stated. It also flirts with the 80% line as well. Since you are referring to the 520 take a percentage or 2 away. Very efficient PSU, NOTHING on Seasonic though.

Hmm? Depends which Athlons and P3s you compared, the early P3s were godawful, but the later ones with full speed cache could edge out the athlons that used external cache. Athlons were still cheaper per performance though and had higher mhz so they had higher performance overall, plus once the athlons got integrated cache and DDR, there was really no comparision between the P3 and Athlons. Even the Durons could often match the P3s mhz per mhz.(athlons typically performed at about the performance of a p3 200mhz above I believe, and durons were about athlons minus 200mhz)

Honestly, from the launch of the Athlon it took until Northwood B where Intel could compete with AMD in overall performance, and Northwood C to surpass noticably, and Intel never matched price per performance.
