IS it true?????

[silverferro]

Hi guys I just came across a article from TOM"S HARDWARE Here which stated "The fastest P4 processors are specified for up to 115 or 84 Watts in Socket 775, depending on the classification and validation of each part after production. For Socket 478, the maximum TDP is 103 W for the 3.4 GHz part. In contrast, the Pentium M numbers are much, much lower. Looking at Dothan, the maximum TDP is only 21 watts, while Banias consumes a maximum of 22 watts" &
that "AMD's latest 90 nm Athlon64, based on the Winchester core only consume 3.2 Watts in idle mode (running Cool & Quiet). An Athlon64 3500+ never required more than 31 Watts even under full load. This is all the more amazing if you consider the performance level that this particular processor delivers"

I keep my computer running for days 24/7.Heat from my 2 BIG harddrives + AGP + AthlonXP 3000+ is worst then global warming effect on my little room already situated on a tropical country and my montly electricity bills are enough to make BUSH & his "intelligence" people to think I'm running a secret nuclear Lab in my home and send his amry to invade my house!!!! LOL

I was actully considering purchasing the new type of computers which are small and run on only 12V dc like this on and with external USB harddrives to save energy but won't give the same performance as the AMD64 but still cost the same as an average system. If this news is true then I can get two in one POWER AND ECONOMICAL.....I will sell off my present setup and get the AMD64.

Before that I need to confirm:

[1] Am I correct to say AMD64 uses less power than Intel P4 & AthlonXP or did I miss somthing?
[2] IF it uses less power then it should also give out less heat compared to athlonxp? Can someone
who has a AMD64 confirm this please with Average Temps during Idle and Full Load.

Thanks in advance

the athlon 64 seems to run about 10 and sometimes even 20 degrees lower than the Barton core Athlon. All using the stock heatsinks.

See my CPU in my sig...idles at 32c, load at 45c with stock heatsink and ceramique. My 2500+ idled at 46c...lol

That link for some reason takes me to microsoft.com. 90nm A64's use much less power than P4's, but i don't know about those numbers or if they use less than athlonxp's.

Yes, the new Winchester core A64's use less power. These are the 90nm cores, not the older 130nm cores like crawhammer.

Currenly i believe that only three A64's come with the new 90nm cores, they are:

A64 3000+ Winchester 90nm core S939

A64 3200+ Winchester 90nm core S939

A64 3500+ WInchester 90nm core S939

Be careful with the 3500+ S939 though, the ealier version of 3500+ S939 used a Crawhammer 130nm core and these produce more heat (use more power).

So in summary if you buy a S939 A64 3000+ or 3200+ it definetely is a Winchester 90nm core. If you buy a S939 3500+ it could be a Winchester 90nm core or a Clawhammer 130nm core, make sure you check the specs and get the 3500+ Winchester core.

that is TOTAL BS. A64's use somewhere in the neighborhood of 40-50 watts load. 3.2w? LMAO!
tomshardware is totally retarded.

3.2 watts IDLE. re-read it.

and yes, those numbers are true.

 

[richardrds]

The 3.2 watts at idle with cool-n-quite feature activated may be correct, that feature lowers all fan speeds and brings the clock speed down to something like 600Mhz vs the stock 1.8-2.6 Ghz. It basically is putting the cpu into a low power sleep type mode while it is idle, as soon as a proccess rquests service it will speed up the cpu to stock speed.

Yea, they are retarded. It's not like THG to be pro AMD when there's no need...

It's even worse than this. Here are a couple of power-consumption charts from Anandtech:

Power consumption for AMD and Intel CPUs

86 watts at idle for the Winnie 3500 (of course, not in Cool & Quiet mode).

He specifically stated that the number they quoted was with cool and quiet mode. Moreover, Idle is Idle, it doesn't matter if one cpu has a certain proprietary feature, if it uses less power when idle, thats that.

Those numbers are the watts the entire system consumed, not just the CPU. I is very hard to measure just CPU power consumption, so anandtech kept as many variables the same and showed us the system power consumtion so you could see how much more power some chips used.

read, those numbers are the ENTIRE SYSTEM, not just the CPU.

edit: oops, repost

 

[neoreturns]

I was under the impression that the 90 nm A64's were max 30 watts

 

[xbdestroya]

This PDF describes the max power consumption figures of the various A64 processors in their different available Cool n' Quiet states. Keep in mind these figures are all MAX, and the processor often will not reach those levels.

http://www.amd.com/us-en/asset...nd_tech_docs/30430.pdf

You'll have to scroll down through it in order to reach the Winchester core specs - it's divided up by steppings.

The Winchester cores are the BI stepping.

Since different sites have stated different results and there is no way of saying who is more accurate since i'm no expert and some of you say measuring the cpu consumtion alone is hard to measure and the results are of the whole system which makes sence. So I have learned a new lesson today. Even if I have a super power consevertive CPU but the rest of the system is not then I'm at square one again. Unless "everyone" manufactures other parts of the computer also to save power then there can never be a system which we can call power efficient.

-One good news is DDR2 will be using less power then present DDR.
-No such news for harddisk or display cards as far as I know.

One good idea will be for harddisks to slow down like the AMD64 during low usage like websurfing,typing a letter on word and so on instead of spinning at full speed. Maybe around 1000~1500 or something like that when left to idle.
And for the display card to run at lower settings during web surfing or less power needing usages and run at full speed during games,3D apps ect and totally shutdown the display card since the monitor will be off when people leave their comp running at night. Less power used, less heat, less noise(fans), less spent on bills!!!! how does that sound? Mother earth will start loveing us again instead of sending us tidal waves and winter storms.

At this point in time, maybe we can compare according to heat during idle and full load among CPUs. Less temp means the cpu is using less power to start with and need a less powerfull cpu fan saving more power.

Start more talks on this topic on forums and manufactures will act on it, i'm sure.

Thanks OrangeParktech for the temps. And the rest of you who have the AMD64 do post your temps too.

 

[CheesePoofs]

The hard drive idea wouldn't work IMO. Hard drives use the most energy when they are spinning up, but when they are at the speed they spin at (7200rpm's for most) they use very little power. If they always slowed down to 1000-1500rpm's when they were not being used they would use slightly less power than if they were spinning at 7200rpm's, but they would cancel out the power saved by useing a lot of power to spin up to the normal speed of 7200rpm's so that they could be accessed.

Also, most video cards use very little power, only the high end ones don't. All low end cards use just tiny heatsinks, and some are passively cooled, meaning they use very little power.

 

[silverferro]

Harddisks can't be accesed when spinning at a lower speed then 5600/7200rpm? I see, i didn't know that. I thought it will just slow down the data accessing/reading time. If it could work then it would not matter though as downloads using present internet speeds can't be faster then what the disk can handle during overnight downloads at slower rpm.

And for the graphics cards, I'm just using normal Geforce MX440, thats the cheapest I can find in the shops now days so presume its the lowest end. Even then it gets dame hot for just normal everyday usage. I have read this somewher and it goes something like this, ( Total power = power used to do the actual work + wasted power(heat) ). If we looked back a few years, we could watch movies and surf the web with thoese PCI grafic cards.They served the same purpose but didn't create that much heat(wasted power). Can that be said today with present AGP cards when we are doing the same things other then gaming and 3D apps ofcos.

Computers have been been made to satisfy the crave for more and more performance over the years but failed to be efficient wasting more power when not needed. Hope AMD64's and Intel's centrio will set the trend for computer makers from now on to follow and make make it easier on our pockets at the end of each month when the bills come.
