Audio Performance

Audio Performance is an area that we will be developing as we expand the new motherboard suite. We plan to provide Quality benchmarks and subjective listening to the more basic performance tests. For this SLI roundup, we limited audio testing to the Rightmark 3D Sound CPU utilization test. This benchmark measures the overhead or CPU utilization required by a codec or hardware audio chip.

Audio Performance - Empty CPU

Audio Performance - 2D Audio

Audio Performance - 3D Audio

As you can see, there was at least one surprise in the test results. The MSI Creative SoundBlaster Live! Chip is touted as a 24-bit hardware solution by MSI, so we fully expected the low CPU utilization that we are seeing in the chart. The other 3 boards all use the Realtek ALC850 codec, so we expected CPU utilization results to be similar. As you will note, the Asus and Gigabyte are in fact similar, but the Karajan module used on the DFI is apparently doing an incredible job on that board. Using the same base Realtek 850, DFI has managed to drop CPU utilization to close to the levels of a hardware solution.

We have to congratulate MSI on their choice of Creative SoundBlaster Live! 24-bit for audio. Similarly, DFI deserves praise for their excellent design work on the Karajan module, which reduces overhead to such low levels compared to competing implementations of the same Realtek 850 codec.

    Wesley did you spend any time at all on this link, I consider this to be a serious issue

    When I set up my MSI board I cannot get surround sound out of the optical digital cable except for DVDs. I verified this on a few web sites. Not why there is conflicting information but mine is real world experience with current drivers (did not use packaged CDs)

    #28, 31 and 32...
    The onboard Creative Sound Blaster Live! 24-bit samples at 192 KHz instead of 96 KHz (like Realtek's ALC880/880D and 850) and features full support for Creative's EAX HD technology. Additionally, the soundcard has also passed Dolby certification for Dolby Digital and Dolby Digital EX and has an integrated Dolby interactive content encoder!

    #41 I've got a TT WS0049 PS, so I should be good with the -5v.

    #43 I've already cancled my DFI SLI DR board. MSI here I come ($238 cdn... so it's cheaper too) :D

    #42 - The on-board nF4 LAN requires a PHY (Physical Layer) gigabit LAN to function properly, but is specified as PCIe. All 4 SLI boards implement PCI Express Gigabit LAN with the PHY chips (Vitesse or Marvel). If you check all 4 manuals you will see Gigabit PCIe LAN specified by all 4 for the on-chip LAN.

    #40 - From the MSI manual Audio specifications:
    "Dolby Digital Encoder. 24-bit/96-192kHz audio quality. Up to 100db SNR. 7.1 channel H/W audio."

    Wesley,
    "all 4 SLI boards implement PCIe on Gigabit #1"

    I don't think the onboard LAN on the nForce4 chipset uses the PCI-E bus, are you sure about this?

    Here's the address for a MSI forum note concerning the problem with the Creative onboard sound and power supplies without a -5 volt connection.

    http://diamondclub.msi.com.tw/eng/forum/viewthread...

    And, if you take a look at the ATX12V Power Supply Design Guide, you can see that the lack of a -5 volt connection on many current power supplies should not have come as a surprise to MSI.

    WOW! This is looking good...
    Manual available here:

    8 Channel & SPDIF audio effect

    Page 5-8
    After installing teh creative audio driver, you are able to use teh 2-,4-,6- or 8- channel and the SPDIF audio featre now..

    Page 5-11
    Decoder shows SPDIF Passthrough option!!!

    I am not familiar with the old Creative Live 24 hardware or menu settings, but is this new?

    BTW: If this is the case, I am canceling my DFI preorder (I've been waiting almost 1 month for this board to become available....)

    Good things may indeed come to those who wait! There is no better way to hook up to my Z5500's if the encode is supported!

    #28, #31, I'd really like to know as well...

    #32, I guess this is brought up, because of this statement in the roundup (on the first MSI Page)
    "The Audio also fully supports Dolby Digital encoding, which will matter a great deal to some users."


    Anand, is this some sort of typo, or can the onboard solution in facte ENCODE dolby digital audio. The ENCODE assumes that it can take .wav audio and encode it to dolby digital and place it on any (analog/SPDIF Coax/Toslink) output (ala IntelHD and SoundStorm)

    Let us know :D
