Audio Encoding Performance

We will utilize iTunes 7.3 for our audio encoding tests as it is one of the most utilized audio applications available due to the immense popularity of the iPod. We just completed testing with the 7.4.2 release with the results only improving by a percent or two.

Our first task was to figure out what test CD to utilize. We needed one that contained a significant number of tracks and had over 600MB of data in order to properly stress our platforms. After rummaging around the lab and discounting the Burl Ives Greatest Christmas Hits album, we happened upon a CD that would work for our purposes as it was not working for anyone else, INXS Greatest Hits. This one time '80s glory masterpiece contains 16 tracks totaling 606MB of songs that was instantly whisked into our anxiously awaiting optical drive.

Our first test consists of utilizing iTunes to rip our INXS CD in WAV format onto our hard drive. Even though CPU speed and optical drive selection have a great impact on these test results we are using the same optical drive between platforms for each test.

Our test platforms score within 1% of each other. This test was very consistent with each result never varying more than one second from the base score as the test heavily relies on the performance of the optical drive which results in test result margins that are minimal. However, we once again see the ASUS board leading a benchmark that is heavily dependent on the storage system.

Our next two tests have us utilizing iTunes to convert our WAV files into ACC or MP3 compatible formats. We utilize the 320kbps and variable bit rate option for both tests.

iTunes normally favors a system with excellent CPU throughput and these tests indicate a balance between the Intel G33 and the AMD Radeon X1250 chipsets. The differences between the boards is around 1% in both tests but the ASUS board tops the charts again.

    When building a couple computers for work using the MSI P35 Platinum board, it appears they don't support eSATA hot-swapping, at least not in XP. I know my Foxconn G965 board at home can do it. Is this behavior still present in the MSI board here? Is it a P35 limitation, or BIOS, or what?

    I dont get it...

    an svdo card (add2-n) with dvi output costs what $6 on ebay. why dont you guys just buy one, so you can test these with digital.

    also the video driver in vista 32bit is not as mature still as the recently released gma 3000 compatible XP driver.

    most people actually have XP so could another round of benchmarks in XP be run? I probably wont even get vista for at leas tanother year, since well its pointless and has no reason for being bought at this point.

    Well.. it seems like you're using Windows XP and a monitor via VGA. Then why bother with these new IGP-based mATX boards? 915G/945G (or GeForce 6100) series would be a better choice for you. They are a lot cheaper (~$50 probably) and XP support is as mature as can be.

    In the center of this new wave of IGPs is the advent of HD contents. Vista is kinda necessary-evil in a sense but in general it handles HD and multimedia contents a lot better than XP and has a more intuitive/prettier UI for a living room environment. CRT has long been dead in living rooms, and if you prefer CRT over LCD for some reason (professional gaming maybe?) IGP wouldn't be an option to begin with.

    I'd say DVI is the minimum requirement, HDMI w/HDCP being a preferred solution in these days and nights.

    One thing that may have been overlooked.. The MSI board is the only one suitable for people looking to use a dual-slot graphics card as well as, say, a creative sound card, with some space between them. For that reason the only board reviewed that I would look at buying would be the MSI.

    From page 1:
    quote:

    The innovation in the IGP market has been lagging for some time but has picked up in recent months with the introduction of the AMD 690G, AMD Radeon X1250, and now the NVIDIA MCP73 series. All of these solutions offer native DVI/HDMI output, HD decode and playback, ...


    Read the following Nvidia pages and the news is somewhat disappointing re HD video.

    Summary PDF -- http://www.nvidia.com/object/IO_35712.html">http://www.nvidia.com/object/IO_35712.html

    PureVideo is only listed for the MCP78 (7050PV+630a) combination. All the other AMD chipsets and none of the Intel chipsets have PureVideo HD.

    If, in the future, they release an MCP73 using (say) 7050PV+630i then memory will be limited to DDR667.

    There is no details thus far, but what would be good is if the new chipset fixes the HD Audio problem that all current HDMI video cards seem to suffer from (i.e. the problem whereby the chipset supports HD Audio, but the video cards can only accept SPDIF-grade audio for HDMI pass-through).

    Everyone who is letting these boards have it for not including HDMI/DVI is completely right. It makes no sense. Sure, I could buy a cheap DVI graphics card and stick in there, but if I have to do that, why would I buy a board with onboard graphics in the first place?

    Sadly missing from this review is the board that DOES include onboard DVI, Intel's own DG33TL. Even sadder is that it takes Intel to make the feature-full board while the OEM companies go for the minimum.

    I agree with the others, as most computers I build have IGP's, being able to directly compare each of the available IGP's on the market would be about the best thing from a review for a long time.

    The 6100/6150SE should also be included as this is still widely sold.

    Also of interest would be a summary of what other nVidia and AMD IGP's are on the horizon.

    Thanks!

    "We generally feel that users like to install games into the same colored slots for dual channel operation, but MSI chooses to color channel A orange and channel B green."

    I wasn't aware you could install games into DIMM slots.

    Sorry 'bout that - I was helping Gary out a bit and managed to mangle the text. Blame the speech recognition. That or I'm just slurring my words a bit. :)

    great article tackling most the issues that we care about!


    question #1: why bother reviewing boards without DVI or HDMI?

    whether we are building pc's for friends/offices etc, or an office/server box for ourselves, or we want it to find a home in its post-gaming life when we ditch it for something better... DVI will be key. inexcusable that they pinch pennies there and frankly not worth your time considering these boards. gigabyte has a g33 board with dvi/hdmi, as does intel...

    question #2: this would have been muuuch more useful like 5 months ago when G33 was new. now it's about to be eclipsed by the 7150 and g35.



    overall i cant wait to see a similar roundup with modern chipsets like g35/nvidia 7150/ g690 and 7050pv for amd...

    would be interesting to see a cost/perf of integrated platforms including cpu costs...
    mobo + cpu costs... it seems amd has some good cheap 690g boards out there, with dvi/hdmi for around $75. (almost $50 cheaper than a g33 board with dvi)...
