System Builder Marathon, Q1 2013: $800 Enthusiast PC

Power And Temperature

At this point, the power consumption chart we see below should have been expected. We're already well-acquainted with the Ivy Bridge architecture's efficient nature compared to anything we've seen AMD achieve with Piledriver. But it really hits home when you consider that we used a 520 W power supply in an $800 build, and barely topped 350 W of consumption with our CPU and GPU overclocked. I don't think I'd be comfortable using the same PSU on last quarter's build, which approached 500 W when we overclocked it.

The thermal results come in fairly close to each other, though Intel's CPU does heat up quickly when we apply more voltage and a higher multiplier to it. Rosewill's RCX-ZAIO-92does a great job at stock clock rates. However, it's quickly overwhelmed when the Core i5 is pushed to 4.4 GHz (it makes sense now that Thomas said, "Though it was somewhat hot and noisy on our Core i7 test system, we could recommend the Rosewill unit specifically to Core i3 overclockers with extremely tight budgets" in his review of this sink).

Considering the FX-8350's high power usage, the $1,000 build’s Xigmatek's Loki heat sink does quite well in comparison.

  • That's a great value PC there. Would be hard pressed to think of a more compelling combination for the money. Well done.

  • The table outlining the components of the build. It should read 800$ and not 1000$, I think?

  • The heat sink breaks easily but it is a good cheap solution, as long it doesn't break.

  • If this machine were at $1000 budget, might as well add a 128GB SSD, and replace the HD 7870 to a HD 7950.

    there would be marginal performance boost from switching from a 7870 LE(nerfed 7950, heck can call it a 7930 and it would be partially correct in a way) to an actual 7950. Though its likely the outcome for the 1k budget coming up next.

  • I really wasn't expecting the AMD chip to be so close to the i5. I'm a bit surprised. The power consumption figures look bad for the FX though.

  • I would like to see builds for non-overclocking as well if they are comparing non-overlocked benchmarks. The $800 isn't a good estimate of what you can achieve in a non-overclocked build when you are paying all that extra for unlocked parts. A locked i5, locked mobo, no heat sink, and smaller PSU will scrape enough for a small SSD. This would be a more well-rounded build that a lot of people would choose especially if they are not planning on overclocking.

    That's cuz the 8350 is using a 670 which in GPU heavy titles will boost its numbers higher. Same GPU would show a more different story and the price difference between a 8350 and a i5 3570k is only able to bump a 7870xt to a 7950 at most, not to a 670

    For a $800 budget, I would rather get all the real in game performance I can first while and add a ssd later than lose out on fps and get faster load times

    higher fps(stronger cpu, gpu) > faster load times

    $35 saved from cutting cooler and k is not enough for an SSD

    After looking at this it would seem illogical to buy a 8350 over a I5. But yes it does do decent interns of price/performance.

    This would have been correct for a "$800 Gaming PC" .
    But for a "$800 Enthusiast PC " , a SSD is a must. Even a 64GB, lower end SSD would have been OK.

  • i am a bit surprised.
    this build looks like a budget-upper-midrange build (if that makes any sense). the mobo... looks weak. the cooler and gfx card looked... cheap. i didn't expect the oc core i5 3570k build to keep up with oc fx8350 build in threaded benches (for $200 less, even). only 7zip seems to take advantage of 8 integer clusters/cores properly and the rest of them don't seem to scale well beyond 4~ cores. i noticed that trend in games but this is the first time i've seen it in non-games softwares. i use handbrake, lame mp3 and archivers (7z, zip/rars), so those benches were very informative for me. thank you.
    when i first started reading, i wanted to see an fx8320, cm hyper 212 evo(or a corsair clc) with a sturdy 970 mobo + radeon 7870xt. as i read on, this current build and its performance started to look more and more interesting.

    The difference between the 7870 XT and the 7950 can be huge when overclocking is considered. That lost memory bandwidth is no small matter for Tahiti LE when it runs at around 1.2GHz. I also suspect that the lost compute units from 28 to 24, although not a significant loss, are considerable.

    Also, not only are the 2560x1600 bencmarks not the only ones showing such a comparison, but also the 1920x1200 and 1680x1050 benchmarks. This is also fairly consistent across most games. Both of these claims are demonstrated to be true by the rest of this article.

    We could easily scrape out enough money from the budget for a decent 60GB/64GB SSD such as Plextor's M5S 64GB without really hurting core performance, at least if we didn't stick to Nweegg (granted Tom's doesn't have much option left in that if they want free systems to hand out). Loading times alone could be worth it.

  • The i5-3570K's overclock appears to be "4.4 GHz @ +0.085 V" as opposed to showing "4.4GHz @ 1.15 V".

    I'm wondering if Blaz's disable-one-core-per-module trick would help Piledriver here, as you'd have a single core with access to 2MB L2 and 2MB L3 without the scheduler needing to worry about the second integer core. As it is, even if the software could make full use of all the CPU cores, they'd likely have a memory contention or bandwidth issue.

    Steamroller will definitely improve matters but AMD will continue to be behind until anybody but the creators of 7Zip thread their software to hell (outside of rendering and productivity apps, of course).

  • These results are pretty eye opening! I already knew it, but dang. As an AMDer, I can't wait for Steamroller (good thing I get to see Haswell first). They need to improve performance, but power consumption as well. No excuse this time around.
