System Builder Marathon, Q1 2013: $1,000 Performance PC

Power, Heat, And Efficiency

The presence of only one graphics card gives our current build a big advantage in power consumption. It also proves that we were wrong to assume we'd need more than a 380 W power supply. Our measurements apply to the complete build, including energy lost as heat within the PSU. The 400 W maximum input reflected for our tuned configuration corresponds to a 340 W output at 85% efficiency.

Our current build’s CPU also runs much cooler at 4.40 GHz compared to last quarter's overclocked build. This is in spite of the previous build’s use of a nearly identical CPU cooler, the same core architecture, and a lower overclocked voltage. We could credit part of the current system’s relatively cool operation to our own side-fan placement optimization, but we also know that Hyper-Threading facilitates better utilization. So, doubling up on Prime95 threads could very easily tax that platform more acutely, hurting thermal performance.

Since our new system is the competitor, we used the previous build’s stock performance as the baseline for our calculations. The new build starts out 25% slower, and its overclocked configuration finishes 22% slower than Q4's tuned machine.

The purpose of calculating average performance here is that it allows us to compare average power in our efficiency chart. Those calculations result in a baseline of 100%. But we subtract 100% from all of those results, since nothing can be more than 100% efficient. The resulting chart shows how far each alternative configuration deviates from that baseline.

Lower energy consumption allows today's build, which is marginally slower, to establish big gains in energy efficiency, gaining 49.5% in stock trim and 35.6% when overclocked. The reason the overclocked configuration picks up less efficiency is because its power consumption goes up faster than performance.

    Isn't this basically the same thing as the $800 pc but with an ssd?

    I think they should have compared the benchmarks with Q4 $1000 pc.

    stoogiepoor build, psu too crap, no storage. a expensive version of a 7870 for no reason at all < waste of money
    And my boss wonders why I hurl insults at people who comment without actually reading the article.

    Now instead of insults I can tell people "Don't be a stoogie". Thanks!

    Pretty much. Not really a fan of any of the parts other than the CPU and GPU...

    The only thing i could have tried to change in this build was to get a 64GB SSD , get a 500GB HDD , and if i have any money left, try to get a HD7950.
    Otherwise, not much wriggle room here. Nice build!

    I'm not sure if having an SSD without an HDD is an attractive option for most people. 240GB goes by pretty fast.

    It actually plays Skyrim WORSE than the $800 build...

    It's the same PC as the $800 build except they just swapped out the HDD for an SSD. Dissappointing.

    No point, We Like Our Games To Load Fast!!!
    Chairman RayI'm not sure if having an SSD without an HDD is an attractive option for most people. 240GB goes by pretty fast.
    Programs can eat most of a 240GB drive up. In fact, I just shrunk a copy of the test suite, with OS and games, to 132 GB.

    Using the drive performance measurement to reflect program load times means loading all the programs on the SSD. And that explains why SSD capacity wasn't sacrificed to make more room in the budget for an HDD.

    Nobody knows why, but the $800 PC did use a newer GPU driver.

    So it's going to lose the Day 4 Value Roundup, right?

    Looking from another perspective, these two builds, with two different builders, with $200 difference, just show(again) how much better price/performance wise are Intel CPU's and AMD GPU's.

    I see your point, but I'd rather see slower game loads and better FPS , than faster game loads and lower FPS. And, the OS is accelerated in both cases anyway.

    You guys must really want me to buy that 7870 Myst Edition. I'm actually hoping to see 2 of those cards in a crossfire configuration on the $2000 build.

    Builder 2 copied Builder 1's power supply. Builder 1 copied builder 2's RAM. Both were stuck with the same video card due to availability issues :)

    Performance difference between Tahiti and Tahiti-LE is fairly small, right? But the price difference isn't small, is it? $1000 PC builder simply hoped for a better overclock, even though that didn't work out.

    Nobody wants you to buy the Myst Edition. Tahiti-LE is a good value, if you like that argument pick your favorite vender. Vender choice wasn't available on purchase day.

    But hey, I'm on board with the 7870 Myst Edition CrossFire suggestion...I'll see if we can make it happen!

    Good call on the bigger SSD over a HDD. Not sure what folks are filling them up with. My other PC has 250GB drive with 400 or so CDs ripped to it, thousands of photos, lots of docs and the office suite and isn't full. Die mechanical drives. Just die.

    Im going o defend their choice here, this isnt "Build the best gaming pc for the money" its to build the best performance PC for the money. And having a large capacity SSD along with mid-upper end CPU/GPU seems good to me. If they wanted to build a pure gaming PC the extra $200 would just be spent on the GPU.

    I think theres something to be said about the value at above $1000 though.. past this price range, people really start caring about having a nice case, nice cooler, etc that are more than just performance but aesthetics too.

    Just do a $2000 build and name it something as "Imaginary build" or something stupid but just do it as a reference for those who may actually spend $2000 on a build.

    I think these would be more interesting if they pitted AMD against Intel/NVIDIA at the same price target.

    Most likely they'd end up with a similar ugly case that no one would really want, possibly the same memory and hard disk, but the heart of the system would always be different.

    Besides, people love rivalries. Sure, AMD processors blow in absolute performance, but they're cheap, and maybe the video card can save the day against the evil Intel/NVIDIA empires. It's a lot more interesting than testing two essentially identical machines, except for the hard disk.

    Do it for different price ranges, and it might even be more competitive. $500, $750, and $1000 might not all have the same winner.

    Totally called that the gpu wasnt going to change. marginal benefits to fund the difference between the 7870 LE and 7950.

    Every time AMD CPU's lose, AMD fans scream that it was intentional. And why would anyone want to pair Intel with Nvidia when Intel with AMD has so much performance for the money?

    Lets do a "Worse of" builds, just for shites and giggles
    Pair a AMD CPU with a Nvidia GPU. So its expensive and may not perform as well.

    (I will be extremely happy if this build performs well)
