Power Consumption

We measured "system" power consumption at the wall outlet using a Watts Up Pro power meter. We do not include the power numbers for a monitor or external speakers; however, we do install a set of headphones to the audio out jack. We also turn on all peripherals in the BIOS along with enabling all power saving features. Power consumption was measured at idle after a 15 minute period and under a load while measuring the average power consumption of the Ambush level in Crysis Warhead. Windows Vista is set to balanced performance mode and the prefetch folder is cleared for each test. Our two tests consist of the standard BIOS power savings mode and a second test using the energy saving applications provided by each supplier. Today the latter consists of the MSI, ASUS, and Gigabyte boards.

Idle Power Consumption

Load Power Consumption

At idle with the BIOS only setup, the Intel DX58SO has the lowest power usage and is followed by the MSI, Gigabyte, ASUS, and EVGA boards. The load numbers favor the Gigabyte board with the EVGA once again utilizing the most power. Our power numbers have fluctuated greatly as the BIOS designs have improved for each board. EVGA just delivered a new BIOS that we are testing now that addresses S3 resume problems and should improve power consumption numbers also. The latest Gigabyte BIOS also provided a significant decrease in idle power consumption as it originally matched the EVGA board.


Power Savings due to Custom Power Design


Power Savings due to Custom Power Design

The MSI Greenpower system provides the greatest power savings compared to the ASUS EPU-6 and Gigabyte DES designs at present. The MSI board has an idle power reduction of 9W with the ASUS and Gigabyte boards dropping 5W. We noticed that even under gaming, each design managed to save a few watts during our load testing. We utilized a beta version of Gigabyte's DES software that has preliminary support for the X58. All three suppliers indicated we should see slightly better results in the next round of BIOS and software updates.

    Im glad Anandtech is taking a firmer stance with the motherboard makers. I too have seen a degradation in quality over the years.

    I take what review sites say with a grain of salt. People concerned about stabilty should go to the motherboards makers forums(or other user forums) to really see what to expect with a product.

    You dont need to be einstein to realise that manufacturers send hand picked and tweaked products to review sites. Their sales figures depend on a good review, but then the masses who buy the boards/products from the shop see very different results.

    Also its hard to poorly rate a product when reviewers have friendships at the companies or depend on advertising revenue from these same companies.

    Whats the use of high overclocks if you cant get 4 Gigs of ram to work? Or your new PCI-E 2.0 Video card is having "compatibilty" problems with a board advertised to run it? Then they say its your PSU or memory. The PSU maker blames the motherboard, everyone blames each other and us suckers have to go out and buy 2 PSU's, 2 different ram kits and mix and match to get a working system.

    I like to buy high end parts but my experience is its usually not worth it. Most "high end" boards, PSU's , memory are overpriced and provide little or no better experience than a mainstream parts at half the price, except maybe graphics cards where a high priced one will provide a better gaming experience on high settings.

    Even in crossfire/SLI an X38/X48 board running at 16X/16X will perform no better than a mainstream P45 board running at 16X/8X. Even worse in some situations.

    X58 is a little different because its a whole new architecture that looks interesting but really doesnt offer a huge performance gain. We will probably see the socket 1156 boards performing about the same if the past is anything to go by.

    Anyway something needs to change in regards to reviews. Maybe review sites should only test parts obtained from retail channels. Maybe review sites should run a standardised lot of tests before even considering overclocking results. I expect all the advertised features to work correctly as advertised.

    Like i said, the best thing consumers can do is, dont take too much notice of reviews and go to the manufacturers forum or other user forums to see what you're really in for.

    I love the fact you are trying to implement changes in how you review hardware. Personally I do not overclock, dont want to but i do want the newer Intel processor/motherboard combo for 3d rendering and just because it is time to upgrade I should go with the future. Not all your readers want to burn up cpu components some of us just want a good honest working system.

    That's it?!
    After promising snippets for weeks, the final article is a compilation of what's been said before. That, and more promises future articles will be more in-depth about: RAM… non ES CPUs… the two or three X58 motherboards not covered here…, etc., etc., etc.

    I appreciate all the work that goes on behind the scenes to make reviews. But at some point you gotta tell it like it is. If a BIOS or driver wasn't ready-- tough luck. There's plenty of room for other companies to shine by getting things right the first time. Or, are sites like Anandtech the new beta testers?

    "We still have several boards to review, ranging from the $220 MSI Platinum up to the $400 Foxconn Bloodrage with several in-between. Our next review will focus on the "lower" end X58 boards from Intel, Gigabyte, Biostar, and MSI. Our final review will feature the upper end boards from ASUS, Gigabyte, DFI, and Foxconn. In between, we will provide a comprehensive OC guide along with a detailed look at memory performance with several DDR3 tri-channel kits from Corsair, OCZ, Patriot, GSkill, Kingston, Crucial, and Mushkin."

    Say it isn’t so. Why did I read this article for?

    I'll try going from the bottom up...
    >I thought the Nehalem memory article was out already. There's that much memory performance left to be covered?
    >How can readers make use of "a comprehensive OC guide" that's coming out before "upper end boards"? There's no point if a few bucks more can get you a board that goes as high as your attempts to OC the cheaper one. Might as well pay more and OC more, or pay less if both have the same ceiling.
    >The next review will be about lower end boards like Intel's?! Huh?! The Smackover retails for over $250 USD. Unless they have a cheaper board nobody knows about, and they're ready to sell it now; there's NO SUCH THING as a low end X58 board this year.

    This article's conclusion, as of 12/05/08, seems impartial and has constructive criticism for the board makers. Perhaps this whole series of articles and blogs will look good to someone reading them for the first time 6 months from now. But, right now, the article is just fodder.

    Are readers better off with an expensive board they know thanks to this article, or should they get an even more expensive board that’s been skipped from this review? Heck, maybe the best is a cheaper one whose price puts it in the so-called ‘low end.’
    These boards are not $1-$5 dollar items. So, say it like you mean it.
    KTHX.
    Or... charge manufacturers for all the beta testing you've done and the many 'second' chances they got before you went public. While you're at it, spare us from dealing with ads in your Web site.

    PS: I wrote this before I read any comments. Boy am I not alone!

    Err... i'm pretty sure i'm just feeding a troll here... but here goes:

    Do you not understand what quotation marks mean? You know... somewhat sarcastic? they specifically put the word "lower" in quotation marks, so unless you truly have no grasp of the english language, you must be retarded to think that they actually meant those boards are "low end" boards.


    "This article's conclusion, as of 12/05/08, seems impartial and has constructive criticism for the board makers. Perhaps this whole series of articles and blogs will look good to someone reading them for the first time 6 months from now. But, right now, the article is just fodder. "

    So... what you're saying is... "WAAAAH! ANANDTECH DIDN'T TELL ME WHAT I SHOULD BUY! WAAAAH! THEY'RE TOO IMPARTIAL! WAAAH! THEY SHOULD BLINDLY GIVE ADVICE OVER THINGS THEY HAVEN'T TESTED YET! WAAAAAAAAH!"

    Right.

    Which companies have better quality control out of the gate is information of EXTREME relevance to the consumer. These boards are close enough together in pricing, features, and performance as makes no difference to me. Which company's board had the least problems when it was shipped to you would absolutely sway my purchase. Also, how quickly they dealt with problems you brought up, and how obsessed they were with overclocking performance results to the exclusion of basic functionality would be a huge factor for me.

    Inform the consumer! Report on hardware? Tell us which companies deserve our money.

    Perhaps you should send the mobo manufacturers a bill for your testing. It sounds like Anandtech provided a very valuable service since clearly the manufacturer's quality assurance processes are not up to the task.
    Yes, overclocking is fun, but if I buy a production board, it had better be production ready. Also, whether the board is $300 or $65, that sucker better work.
    I'd actually like to know which manufacturers we're discussing as I'd like to stop supporting them with my dollars until they get a clue.

    It's hard not to rant here, but I know that rants often get passed over.

    You guys don't know what a relief it was to read this article. I've been building systems for many years and I have noticed the steady decline in quality.

    My latest build was not only the most money I've ever spent on a computer, but also the worst experience I've ever had with a build. I've since sold it off as pieces, while I contemplate buying a preassembled workstation for the first time in my life.

    The final straw for me was when I complained about a broken feature to a well-known manufacturer and they told me that I "should have known" what to expect from their product by reading their message boards. In other words, we know it says it does A, B, and C on the box, but if you read our message boards before you bought our product, then you would have known that it doesn't do A, B, and C.

    I hope you guys can turn this situation around.

    Anand's essay on this topic is some of the most important writing I've seen here. Unfortunately, the editorial slant of AT reviews, along with many other sites, has set the stage over the years for exactly what the complaint is about. Anand describes it well...the overriding interest, if not outright obsession, with what often amounts to miniscule performance advantages has literally buried the benefits of simple day to day dependability. Now that this situation has reached such extremes that Anand feels compelled to sound off about it, the task is to turn the editorial focus enough to raise dependability to the higher level of concern that it deserves. Some users in the forums point out at times that different settings or product differences make absolutely no difference in real world use. AT reviews should be equally candid and state, perhaps in bold type, when differences in observed speed are insignificant, and then NOT go on to rank order products on these insignificant speed differences. AT reviews should also go on to provide a rating or at least clear observations about the true ease of use, dependability and satisfaction to be expected by users in general or at different levels of experience, including BIOS issues that the manufacturer has not fixed. It sounds like this might be coming. Great! JDPowers ranks cars on something like initial problems/defects found by new buyers and there's no reason why similar polling/experiences shouldn't be provided for users of what are increasingly expensive computer parts. I hope Anand follows up on this issue and really institutes changes to address it.

    Thanks for the roundup. Great reading.
    I bought the i7-920, 12GB of G.Skill PC3-1333 RAM and Asus P6T a couple of weeks ago, and have only had one real problem. My new Logitech Illuminated Keyboard causes the mobo to take about 3 minutes to initialize USB devices at POST, and then when it does POST the keyboard won't work at all until Vista takes over. Very irritating. Haven't contacted ASUS, because I'm sure they'd point the finger at Logitech, who would point the finger back at ASUS. Besides, the keyboard does not cause any problems on my other PC.
    I should say that I don't and won't be doing any overclocking, unlike most people around here I imagine, but even so I've noticed a lack of attention to detail in these mobos.

    Good article.

    However the feature tables are a rather large download. If you absolutely must post them as an image please use PNG or GIF. I resaved one in both formats and the size dropped in half without a loss in quality. JPEG is excellent where color content is more important than detail. However the indexed color of PNG and GIF is superior for a 2 color text table where the sharpness of the letters and not the exact shades of those two green is most important.

    Also you have a next page link at the bottom of the last page that, of course, goes nowhere.
