System Builder Marathon, Dec. 2011: $2400 Performance PC

Power, Heat, And Efficiency

Liquid cooling pumps are somewhat of a power hog, so we expected our new system to consume a little more at idle compared to the previous build.

Overclocking requires much more power, so its big consumption numbers are par for its superior overclock.

Liquid cooling usually drops temperatures, though sharing a small radiator with the GPU doesn’t help our CPU temperatures compared to the previous machine.

Efficiency compares work to energy, so we first compile a performance chart to gauge work per unit of time in comparison to the previous system’s baseline. After this, we compare the performance ranking to the power ranking.

The current overclocked PC is around 9% faster in games than its tweaked predecessor, but it also consumes more than 9% additional power. Keeping the former system’s standard speed as our baseline, we calculate our efficiency chart around it. Since the baseline is 100% (and yet nothing is 100% efficient), we then subtract 100% from the efficiency chart results to show only how much more or less efficient each system is by comparison.

First calculating overall performance at 10% for storage performance and 30% each for Gaming, Encoding, and Productivity scores, our power-per-performance chart shows that the previous build was more efficient in spite of its lower performance. Overclocking boosted its efficiency by increasing performance by more than power consumption.

A big boost in CPU voltage required by the new system increased its power consumption by a greater percentage than performance, resulting in less efficiency.

    when i first saw "System Builder Marathon, Dec. 2011: $2400 Performance PC" first thing i thought was a x79 build, $2400 just for performance PC using a 2600k CPU i kinda cringe , i cant imagine how much more expensive it would be if u did it with a 3930k, yes i know it not a big different in performance between the two but was just wonder :)

    When I saw how much power this thing sucks down, I was glad to see that it pretty well shows the law of diminishing returns. This does nothing to change my opinion that only where time is money, i.e. for professional use, is this kind of cost justified. Spending this amount of money just to play games is a waste of resources all around, from the money to buy the parts, to the expense of running it. For future high-end builds, please specify the professional and/or his/her software that this machine is being designed to run. Justify the GPU choice by throwing in a GPGPU application that can take advantage whatever was selected. BTW, it does LOOK great; nice case choice.

    Also, as much as I understand the frustration with sacrifices, IMHO that's where the best lessons are.
    Fun to read, yes, but just not practical. Hmmm, I guess that means the downvoting is about to begin...

    So, I wait until tomorrow to enter?

    No, you're good today. It should start with today's story. I'll see if I can get that changed.

    $2400 and no i7 3930K?

    one-shot$2400 and no i7 3930K?What, and ditch one of the graphics cards for a reduced average-performance score? 3930K didn't show up until after the system was ordered, but I stand with the first argument, there's just not enough performance to be gained using these specific apps.jtt283For future high-end builds, please specify the professional and/or his/her software that this machine is being designed to run. Justify the GPU choice by throwing in a GPGPU application that can take advantage whatever was selected.We try to add professional apps that at least a few thousand of our readers have access to, but I'll ping Chris for more. Basically we try to spend our money boosting our own apps and adding a few more is probably justified. Suggestions? jtt283BTW, it does LOOK great; nice case choice.I was a little disappointed in my examination of the Arc Midi, that it's nowhere near as solid as the Arc Mini. I think it's because it's larger (so the bracing bends are further appart). As nice as the Arc Midi looks, the Antec Three Hundred is far sturdier at a similar size.jtt283Also, as much as I understand the frustration with sacrifices, IMHO that's where the best lessons are.Fun to read, yes, but just not practical. Hmmm, I guess that means the downvoting is about to begin...I almost voted you down for saying that... :P

    I can't find the storage benchmarks. Am I just overlooking them? I am thinking about getting the Crucial M4 for Christmas. It seems like a good overall value.
