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.

    Typo on Page 20: I don't think you hit F3, it's F6.

    Wesley, would it be possible to get a reply to the comment #6 i wrote? ASUS worked closely with you to resolve the dual 6800 ultra issue, but they just stonewall me and everyone else regarding the overclocking at 1T issue.

    Perhaps if someone with some "muscle" in the hardware reviewing world were to push them for a response you could get one out of them?

    Thanks, Adam Miles

    #52 - i don't envy what you have to go through. i've had the misfortune of trying to get tech support from asus sometime ago and it was like pulling teeth.

    #29 - i agree. while i would love to have two 6800 ultras or GTs in SLI, the fact of the matter is i can't justify the cost. so instead i'm going with two 6600GTs. although this is apparently not a very popular choice, the fact remains that this configuration is still going to be substantially faster than my current setup using a 9700 pro and it costs about the same as my 9700 pro when i bought it.

    I just noticed that the MSI board lacks additional PCIe boards, where the DFI board has an additional 1x and 4x slot. Anyones opinion on the importance of this? Reply

    I just have to mention to my fellow anandtech members that I have an ASUS A8N-SLI board and I have been trying to get through to their "tech support" Friday and all Monday morning with absolutely no luck whatsoever! You can't even get through to anyone. So, when considering a motherboard keep this in mind. My experience with their "tech support" has been the worst you can imagine. Well...at least they weren't rude or incompetent.... they just aren't there. Reply

    too bad the non-sli from MSI doesn't use the SB audio

    Heinrich,
    Did you configure the settings as per page 5-12 in the manual to passthrough on the decoder?

    How did you make the Gigabyte run 4x dimms at 200mhz?
    I have this new motherboard GA-K8NXP-SLI and 4x of kingston hyperx pc3200 (KHX3200UlK2).
    And running a new AMD athlon64 3500+ 90nm

    I use SPD settings for the memmory. T2 is enabled.
    Do I then force 200 mhz it just frezes.
