Benchmark Results: Audio And Video Encoding

Our iTunes-based workload is single-threaded, so we end up with results that vary based on, one, architecture, and two, clock rate. The benefit of a hexa-core chip is completely masked. Not surprisingly, then, the slightly more efficient Ivy Bridge architecture manages to outmaneuver Sandy Bridge-E at any given frequency.

Despite its complexity, we hit 4.6 GHz on our Core i7-3930K. That's the same ceiling encountered on the Core i7-3770K. But because Ivy Bridge doesn't respond well to voltage increases, heating up quickly, we can't safely push any higher.

Lame is also single-threaded, so its results mirror iTunes.

Both HandBrake and MainConcept benefit from extra cores, but not by as much as higher clock rates. The result is a near-tie between the current overclocked build and the former, six-core machine’s baseline.

    Very nice build, if only I had $1800 to spare

    Well, is GTX 680 availability good enough now?

    i would never buy a green 5400 RPM over a 7200 RPM drive, no matter the cost.

    Awesome Build!!

    I have the exact same GTX 680 from ASUS, and I love it. Managed to get 1337Mhz out of the core and 6800 out of the memory. I achieved that with only 115% power limit. If I raise the power limit any higher, i start to loose performance and stability. That is a truly awesome memory oveerclock you got out of it! Congrats!

    Very much looking foreward to the value comparison.
    Would LOVE to see the 1800$ build win the value comparo!
    GO GTX 680!!

    My vote goes towards keeping a gaming focus as opposed to a more "all-in-one" type build.
    Love the System Builder Articles, love Toms!

    Unfortunately GTX 680 availability is still pretty spotty.
    Had to spend 2 days on newegg, refreshing the page every few mins to get the model i wanted.
    However, it IS looking better. They are listing them more often on newegg, and they don't sell-out as quickly as they were a few weeks ago.
    Check newegg daily from 5:30pm to 6:30 pm CST, and you should be able to catch one.
    The GTX 670's are in stock right now.
    Good luck rohitbaran!

    should we keep the gaming focus or move back towards higher-cost do-it-all machines?
    Personally, I'm happy with the gaming focus. Don't know how others feel but gaming performance is more important than productivity benchmarks for me. I compile a lot of code and do some video encoding but I find gaining fps in games is more important than shaving seconds off my work. Besides, productivity follows gaming performance close enough.

    On another note, I dislike value comparisons when things like SSD size and optical drives have made an impact in price. A larger SSD does nothing for a benchmark but is awesome in practice. I'd prefer only comparing the combined price of the gpu, cpu, cooler(s) and mobo in the value chart. That's not a perfect solution but it annoys me that things like high quality PSUs, nice cases, blu-ray burners and large SSDs throw things off so much.

    My only dislike about this build is the case, for a $2000 PC I would prefer a case that was tidier and larger than the Antec Nine Hundred (especially with the layout of the HDD bays). The NZXT Phantom 410 would be much better for that budget.
