Benchmark Results: Audio And Video Encoding

Converting an entire feature-length movie soundtrack to Apple format in under a minute is something only an ultra-fast processor can accomplish. Unfortunately, the poorly-threaded program probably would have reached the same performance level using an air-cooled i3 processor at the same clock speed.

Leave it to independent programmers to develop a transcoder that actually works--as previous dual-core system reviews have demonstrated, HandBrake’s threading looks superior to that of our other video-encoding programs. Converting a 1GB video file to MP4 in less than 5 minutes strikes us as an excellent use for all that excess processing power.

TMPGEnc encoding times look about the same today as they did six years ago, though changes in the DivX codec might be responsible for that lack of progress. On the bright side, overclocking boosted its performance by 68%.

MainConcept gets a smaller boost of around 47% through overclocking, making us a little more curious about how well the less-expensive systems will compare.

    More than 64GB is gonna be needed for multiple games and good apps... those ssd's can only handle 5 games max.

    You're repeatedly ignoring that it's 128GB, not 64GB, because the article repeatedly states that the drives are striped (Level 0) by the RAID controller. And there's a terabyte of added storage on top of that for stuff that isn't programs.

    I couldn't have made it better. Amazing rig for a 3k budget.

    Nice fail there Zoe.

    This thing is a beast.

    Nice as it is, my only complaint is that...
    Overclocked 5970 + i7 on a single 120.2?
    ARE YOU MAD!
    Likely.

    Well, I personally would have dropped something else and gone for a 120.3 or 140.3 radiator. =D
    Hell, maybe even a 140.4 radiator, but then again, I like my system to run chilly and silent. It's also be very difficult to mount a 140.4 I assume. Maybe I could jack a radiator form work, I think it's about 1 metre by 3 metres by half a metre. Granted, it's for industrial use, but just for one day, please boss please?

    Good results on the i7 though. Decently low voltage and still managed to reach 4.3GHz. My i7 is a lemon. It makes me sad. =(
    Also an impressive overclock for a 5970.

    At this kind of power, you should be testing multi monitor resolutions. I have a 5770 and I run 7 megapixels, you use a 5970 and only run 4 megapixels.

    Looking forward tho the $1,500 build. See how my build compares to one six months older on a similar budget (and cry).

    Well, the explanation is in the conclusion, the builder wanted redundant storage instead of the big radiator but chose neither, leaving enough room in the budget for anyone who wanted to copy the build to make their own upgrade choice.

    But what's not in the budget is that the water was never hot, it was barely warm. The problem with running the CPU at 100% load and the GPU at 100% load is that the water temperature went up by around 10 degrees...we're talking about going from the 30's to the 40's here at full load. The article points to the GPU cooler as a likely flow restriction so I have three solutions:

    Solution 1: Add 1/2" by 3/8" adapter T's and cool the chipset block, parallel to the GPU block. That would allow some of the water to bypass the GPU cooler, which is OK since the GPU was always cold. But 1/2" by 3/8" T's are hard to find outside of a hardware store, and Newegg certainly doesn't have them.

    Solution 2: Switch to a 3-fan radiator. A 4-fan unit won't fit nicely into that case, and making an ugly system wasn't considered a solution.

    Solution 3: Add a second liquid-cooled 5970 parallel to the first. Get twice the GPU power and completely unblock the lines in the process. The GPUs would run slightly hotter when each gets only half the water, but at least the CPU block's flow won't be restricted. And...since it's probably adding another 10 degrees to the coolant...stick the three-fan radiator in there as well. For FOUR grand you could have a KILLER system!

    OK, so solution 1 is the cheapest, but you have to admit solution 3 is tempting...

    I kinda like it. Dramatic power increase for the overclocked components. But also dramatic performance increase.

    Another solution to the constricted water flow would be to change the block on the 5970.

    This build gets one and a half thumbs up from me, not that anyone cares...
