Power Consumption

Power Consumption

For all testing, power saving features such as AMD’s Cool’n’Quiet, (and Intel’s SpeedStep) were disabled, and Windows Vista’s power option was set to high performance. Let’s take a look at the total system power usage measured from the AC source. 

Using the boxed cooler prevents us from pushing too much CPU voltage, which then keeps both overclocked systems’ idle and CPU load power consumption from skyrocketing. The better gaming performance achieved with dual Radeon HD 4850s does come at the expense of greater power consumption. 

We don’t have data from the previous SBM articles, but considering the platform change and that the CPU readings used are core temperature measured by AMD OverDrive and Core Temp, the comparisons are better left to stock versus overclocked on the same system. When looking these over, remember that when we overclocked, the automatic fan control was disabled, so the CPU and two graphics card fans were running at 100%.

    A nicely done build, great work with overclocking on a stock cooler and an impeccable write up. Thanks for the great article Mr. Henningsen. AMD did a good job for a budget build, especially at stock clocks.

    Great article! It's crazy to see all of that packed into a case for only ~$650.

  • I usually love reading these, but this time I just went directly to the comment section. There's no point in building or owning an amd box, they are too weak compared to modern Intel/Nvidia based systems.

    Wonderful. =D

    What about the new $100 quad core athlon with no L3?
    I know I like extra cores. Wonderful choice regardless.

    I wonder what the quad core athlon with a 512MB 5850 (which would increase the budget though) will be like. Both cheap yet highend parts. =D

    Nice to see what only a pocketful of cash can get you.

    i know it wasn't available at the time but what about that 100 dollar quad core the athlon II x4?

    Good article. I know you stated you were leaving the "unlocking" of the other cores to the winner of the contest, but were you guys able to unlock? If so, could you re-run those benchmarks? Again great article.

    While "forcing" all AMD builds for a single marathon is a good idea, the timing is somewhat unfortunate.
    An article which explores the performance and value of a complete Lynnfield build is something I (and many others, i'd dare to guess) would like to see but haven't yet, and this month's SBM is a missed opportunity in that regard.

    That's a bitchin budget gamer system especially looking at the gaming benchmarks.Just this month I was thinking about building a similar type of system with the Phenom II X2 550BE.I was going to go with gigabytes 785G type board (just one graphics card slot) though however I may reconsider that especially with what you presented here although I was shooting for a much cheaper budget build (about $180 less than what you have),Newegg did have a gigabyte 785G board with the Phenom II X2 and $20 off in a combo deal until the end of this month.
    I think that your choices were better than mine (more powerful).

    Another alternate mobo - 785G ...they are availbale in AM3/AM2+ flavours and have SB 710, which can allow core unlocking -http://www.newegg.com/Product/Product.aspx?Item=N82E16813128394
    But not sure about their o/c potential though...

    Nice to see a cheap system still using a quality motherboard.
