System Builder Marathon Q2 2015: Value Comparison

By Thomas Soderstrom
published

Now that we’ve built four PCs with matching budgets, which builder, and which machine, owns the title of best performance for $1600?

Power, Heat And Efficiency

Power numbers are surprisingly consistent between different builds at stock settings, but CPU overclocking puts a big mound on the loaded power numbers of the work machines.

Because the work machine topped so many workstation applications, it came out ahead in the efficiency scale. Because there weren’t any old or cheap machines to use as a baseline, I used the average of all systems instead.

    Test is biased towards work PC. It is hard to differentiate between systems in your graphs.

    5/10.

    That's probably why so many readers demanded a 5820K last winter.

    That's why I retained the same order throughout the article. This chart format works best with 5 or fewer configurations, 6 was a stretch and 8 is too much for some readers. We'll most likely go back to fewer configurations next time.

    Is it just me, or are the noise tests missing?

    I'm not sure I enjoyed this SBM as much as usual. In past cycles, even builds that have been bad have presented additional "data points" to use when evaluating new builds in general. Don's 4x Crossfire HD4850 build, Paul's Celeron+flagship graphics machine, and Thomas' beautiful Antec Professional PC stand out in that regard.
    I'm not sure these systems show anything new or unexpected, although there may still be people who don't realize just how effective mini-ITX can be. The silicon lottery played its part, and thermal problems raised their ugly head as well.
    Not to defend "we've always done it this way," for its own sake, but I'm sure I'm not the only one a little exasperated by some of Julio's choices and methods. With few exceptions, I could see why any of the three previous builders did certain things (Don's cheap case selection(s) being one of those exceptions), but I hardly know where to begin with Julio. It's not even that he's blatantly "wrong" about things, but his builds felt awkward; maybe like music where A=432Hz is notably different from music where A is tuned to 440Hz.
    Of these builds, I prefer the mITX boxes. My own games and single monitor need nothing more than a GTX970, so that makes Thomas' little box the one I'd prefer to win.

    Am I the only one who can't see a big case such as the Rosewill Neutron as an ITX? I mean, it's like a regular tower, just two bays lower. Compare that to DIYPC's case, now that's something you can call compact.

    I kind of agree, but that's because mini-itx cases are kinda weird as the are likely one of two extremes. They're either short and long, like the coolermaster elite 1## / haf stacker series, or tall and "fat" like the rosewill neutron. (HTPC cases are a different class)

    Since the little cube PC was the only one of mine (the workhorses) noticeably noisy, I measured it. Overclocked, it produced 42.4db under combined load (card spins up), 34.3db idle. I reset it to stock, and it dropped to 35.9db under combined load and 32db idle. Both of those are at 1m. Since the full tower didn't get my attention, I can guess it was at least 6db quieter.

    I never got a chance to hear the gaming machines running.

    I'm sure the tests were done as accurately as possible, there will always be margins for error but a few of the test results seemed really out of place. For instance the 7zip times. The gaming pc scored the worst/slowest but when oc'd it performed even better than the oc'd work/performance pc? By a huge margin no less. I can see there being different variables due to program behavior, how well it makes use of multiple threads and so on. It doesn't explain how there was such a huge leap from stock to oc'd game pc build vs the much less significant jump from stock to oc'd performance pc. Many results were in line with one another while others seemed to be all over the place.

    I like the theory of this SBM: every system gets equal money but different themes. Doing such should reveal how shifting balance around in system components affects overall system performance. But I have to agree with Joe. It just felt . . . awkward.

    My guess is that the program crashed but the timer closed without registering the crash :) New builder doesn't know what an errant result looks like yet, but he's learning quickly!
