Power Consumption

As always, we measured power consumption at two states: at idle sitting at the Vista desktop and under load while running our WME test.  At both settings, Cool 'n Quiet/EIST were enabled to keep power consumption down to a minimum, although the biggest difference is made at idle.

Keep in mind that the X2 5000+ listed here is a 65nm Brisbane core, while the rest are 90nm parts.  The X2 3800+ is a low power EE SFF core, although still based on AMD's 90nm process; all of the Intel CPUs are 65nm.

System Power Consumption at Idle

At idle, AMD's power consumption is lower than Intel by a few watts. Keep in mind that our E6300 is a particularly bad sample so it showcases the worst possible power consumption for that particular processor.

System Power Consumption under Load  

Under load it's clear that AMD needs 65nm to be competitive with Intel as only the 65nm X2 5000+ is able to draw power similar to that of its Intel counterparts. Note that AMD is at a bit of a disadvantage here as it's running on a more power hungry nForce 590 SLI chipset compared to Intel's P965, but the power requirements at 2.8GHz - 3.0GHz on AMD's 90nm process are quite real.

AMD needs 65nm top to bottom in a bad way; not only will it help ease capacity constraints, but it will also keep AMD from turning into the power hungry chip maker that Intel once was.

    ASUS M2N32-SLI Deluxe

    are you useing the older corsair XMS2 sticks 1.2v as i cant get my 2.1v sticks to even POST some times in my pc

    allso this test is 2 months old other review good thing is your useing an 8800GTX to test the limits of the CPU, other web site was still useing and ATI X1950 and fiding that thay was GPU limted (dono why thay still bother testing them with that x1950 as the test will be GPU limted not CPU)

    I've been critical of AMD's chances, but they do have a shot - The problem is their chance to catch up depends on Intel slipping up.

    AMD needs a perfect storm to happen:
    1) Barcelona needs re-capture performance/watt leadership
    2) Barcelona neees to re-capture performance/watt be damned leadership
    3) Barcelone needs to ship in big quantity during calendar Q3 07
    4) Intel needs to slip Penryn ramp up to Q2 08 and slip their next micro-architecture to 09

    If any one of these doesn't happen it's going to be rough going.

    Well, the big question, WHY Vista 64 bit ? The other question WHY AMD 6000 + ?

    For me, personally, testing on Vista 64bit, is a bit odd, and perhaps is used to confuse the real subject: Why pay a $200+ premium for a CPU (direct comparrison to the E6600), that only does better in video related applications ? Oh, and in case anyone is interrested, I am NOT a fan boy, but if I were to pick a preffered platform, it would be AMD / nVidia. Currently I'm using an AM2 system, with the best budget motherboard on the market period(this is my opinion of course: the ABIT NF-M2 nView).

    Also. personally, I would have rather seen the data done in XP, because this would give us a real idea of how this CPU would compare to previous tests, and again, in my opinion, was very bad timing on anandtech's behalf if this was not intentional. I've done my own testing in Vista as well, so I KNOW pretty much where the performance differences lie, although I have not personally tested Ultimate 64bit. I, not unlike many others, will not see the need for Vista for at least a while longer, and Directx 10 games become mainstream . . . XP Pro performance data PLEASE!

    The main reason that I havent moved to C2D, or intel as of yet, is simply, because of the motherboards availible for this platform, and I simply do NOT like what the Intel side of the camp is offering, period. Motherboard features / cost, is nearly the only thing keeping me from switching sides ATM, and I for the life of me, can not figure out how AMD gets off charging a $200 price premium for a CPU that isnt very good overall. Now, if some manufactuer, made a motherboard that was both attractive in features, and cost, I personaly think AMD would be in serious trouble, which would be very bad for everyone, not just AMD.

    Based on these 'scores' you've given, I would think the CPU to buy from AMD would be the 5600+, and perhaps that what your conclusion said ? I wouldnt know, I make my own 'assumptions', based on the test data (IE, I didnt read the conclusion) ;)

    Thanks for the good laugh!

    You show me, a good C2D capable motherboard, for $80 usd, that is as feature rich as the AM2 ABIT NF-M2 nView, and perhaps I'll laugh with you. Until then, your comment isnt / wasnt even nessisary.
  • strikeback03 - Thursday, February 22, 2007 - link

    That $200 price premium on the AMD processor you mention plus your $80 motherboard budget will get you almost any board in the C2D camp.
  • yyrkoon - Thursday, February 22, 2007 - link

    Except, that you completely missed the whole point. $80 budget board, does NOT mean, someone is going to go out and purchase a sub $500 CPU for it, thats just silly. However, I also wouldnt stop them from upgrading to that CPU, when the prices drop over time. Also, not everyone wants SLI, or crossfire GPUs, so by the time, you find a board with as good features, be it i680, or one of the Intel chipsets, you gain, SLI, dual GbE, and a very good chance of other goodies, but you lose, integrated graphics, which if you're building a very low budget PC, this can save you a good amount of cash. Also, this motherboard will accept just about any aftermarket CPU cooler you could care to put on it, but honestly, IMO, this isnt a board I'd use to OC anyhow, but it will OC well compared to the cost you put into it.

    There are lots of motherboards out there, that have some very cool features, personally, I really, really like the Workstation line from Asus, 2x 16x PCIE, 2x 133 PCI-X, and 2x PCI 2.3, and I beleive they make them for either AM2, or C2D, but the plain simple fact of the matter is, they also cost more than $300, thats nearly as much as an E6600 . . .

    Take a look at the $80, and under Intel CPU capable motherboards, and tell me you can find one that is as stable, with as many features as this one. Then realize just how many of those, actually supports C2D . . . Trust me, I've looked, because I really want to move away from AMD atm, but it does not make sense, if you have to compromise, on what you get stablity/support/feature wise.

    New A64 6000+ actually performs slightly worse (loses more benchmarks) than E6600. However, A64 6000+ costs $459 while E6600 costs only $316. Worse performance for 45% higher price??? Is that a good deal? Reasonable price for A64 6000+ would be about $300.
  • sprockkets - Tuesday, February 20, 2007 - link

    That $102 dollar 3600 chip and a new AMD HDMI chipset or the Abit 6150 board. For more performance, sure, C2D, but hey, can't beat $102 for good dual core performance.

    I wonder how Fusion will push prices lower...
  • anandtech02148 - Tuesday, February 20, 2007 - link

    At idle and load do these charst include 8800gtx power consumption too?
    Is this the whole system powerconsumption including the graphic card?
    I thought 8800gtx power consumption alone is 245wtts.
