Multitasking-

The vast majority of our benchmarks are single task events that utilize anywhere from 23MB up to 1.4GB of memory space during the course of the benchmark. Obviously, this is not enough to fully stress test our 6GB or 8GB memory configurations. We devised a benchmark that would simulate a typical home workstation and consume as much of the 6GB/8GB as possible without crashing the machine.

We start by opening two instances of Internet Explorer 8.0 each with six tabs opened to flash intensive websites followed by Adobe Reader 9.1 with a rather large PDF document open, and iTunes 8 blaring the music selection of the day loudly. We then open two instances of Lightwave 3D 9.6 with our standard animation, Cinema 4D R11 with the benchmark scene, Microsoft Excel and Word 2007 with large documents, and finally Photoshop CS4 x64 with our test image.



Before we start the benchmark process, our idle state memory usage is 4.05GB.



We wait two minutes for system activities to idle and then start playing Pinball Wizard via iTunes, start the render scene process in Cinema 4D R11, start a resize of our Photoshop image, and finally the render frame benchmark in Lightwave 3D. Our maximum memory usage during the benchmark is 5.62GB with 100% CPU utilization across all four or eight threads.

    785G is just onboard graphics halfbreed between 780 and 790 or whatever. until AMD releases a new line of high-end boards worth reviewing, why bother?

    P55 is just half a chipset, i5 took over some of the functionality anyway ... why bother ?

    Why do we need PCI anymore? I´ll tel you why: The PCI bus is more than enough for a hell bunch of applications, that´s it. If you have a damn good sound card or video capture, or whatever the card you have, and it´s PCI, you´d love to have the slot in there, because you don need to ditch that card and bet a "fantastic" PCIE x1 new card.
    C´mon people, let´s use the computer for the right purpose, not just to give money to the manufacturers buying new parts that you don´t
    necessarily need.

    I know, I´m being inflexible and oldschool, but, please, evolution is one thing, marketing is a completely different animal.

    IMO it is more a board real estate problem than a case of buying the latest and greatest. On these P55 uATX boards you have 4 slots, one of which has to be devoted to graphics unless it is a headless server. If you use a dual slot graphics card (which a substantial portion of the readers on this site) you lose a second slot, and ideally you would have an open slot beneath that to ease airflow. So that leaves you with one or in a pinch two slots, therefore what interface they are is quite important. PCIe has been out on boards for what, 5-6 years now? I'd say its time to stop selling PCI cards and leave the PCI slots only on full ATX boards (plus maybe a few HTPC-oriented uATX boards) and let the interface finally die off.

    Though I'd say IDE has even less of a place now, SATA hard drives have been the norm for years and even optical drives for a few years. Time to upgrade if you are still carting one of those around.

    Thanks Gary for the detailed review. Can't wait for the p55 roundup, and I'm also very interested now in your audo codec review.

    ... but I don't see the sense in SLI on mATX. Using the typical long video cards means you can't have a shorter depth case, just shorter height and since when is the area above your computer case a vital piece of real-estate?

    With 2, 8 or 16X slots onboard it only makes sense to me to go full ATX, is someone with the system budget to build a powerhouse gaming machine really poor enough, indescriminating enough, or young enough (to not have desirable cards from past systems) they don't want to add some other cards?

    I hate to say it but this is getting to be a madness, the idea that we need to focus centrally on gaming ability of a board. Most people are not hard core gamers, but factually speaking, most hard core gamers don't do SLI either. Granted you can use a 16x slot for cards with fewer lanes, that seems the only saving grace for the two boards.

    It's getting to the point I want a cTX case design where the drive racks are not in front of the mainboard and PSU, they are above them, so the case is even taller than std. ATX but not as deep.

    Might tip over a little easier but earthquakes are rare here and plenty of other household items are more tip-happy than that would be.

    There are cases made to hold a uATX board lying on the bottom, making it kinda a wider Shuttle. I'm personally looking for full ATX as well though, as the height doesn't matter too much to me (pretty sure anything short of a ABS Canyon or some of the bizarre decorative cases would fit under my desk) and don't want to limit my slot selection.

    Hey Anand,
    Gigabyte boards have on issue that drives me nuts. As soon as you start overclocking them, you lose the ability to S3 sleep. When you do your maximal overclocks for various board reviews, would you mind testing if S3 sleep was maintained at those maximal overclocks?
  • Gary Key - Monday, October 5, 2009 - link

    This board resumes from S3 (USB keyboard) at up to 215 Bclk (mentioned in the thoughts section, make that more visible next time) with our setup and that includes an external hard drive on the Firewire port which is properly instructed to shut down and restart.
