Audio Performance

We limited audio testing to the Rightmark 3D Sound version 2.1 CPU utilization test and tested with sound enabled to show the performance effects on several games. The Rightmark 3D Sound benchmark measures the overhead or CPU utilization required by a codec or hardware audio chip.

Audio Performance - Empty CPU - 32 Buffers

Audio Performance - 2d Audio - 32 Buffers

Audio Performance - DirectSound 3D HW - 32 Buffers

Audio Performance - DirectSound 3D EAX2 - 32 Buffers

As you can see, none of the onboard audio solutions were quite as low in CPU utilization as the Abit AudioMAX 7.1 solution. The Asus P5N32-SLI Deluxe uses the "almost standard" Realtek ALC850 found in most high end NVIDIA AMD SLI systems. The current NVIDIA driver release limits the 3D sound buffers to a maximum of 48 compared to 25 with the RealTek drivers. It also indicates support for OpenAL with full EAX2 compatibility. However, Quake 4 refused to recognize the OpenAL support and would not allow sound in the game. The current RealTek A3.76 release does not include OpenAL support. We will be updating our test results for the RealTek ALC850 based boards with the newly released A3.78 drivers shortly and providing F.E.A.R. results.

Audio Performance - DirectSound 3D EAX - BattleField 2

Audio Performance - DirectSound 3D EAX - Splinter Cell Chaos Theory

Audio Performance - Wolfenstein - Enemy Territory - Radar Demo

The Battlefield 2 numbers are interesting as the Asus P5N32-SLI Deluxe implementation of the Realtek ALC850 sound solution creates a 12% loss in frame rates. This compares to 27% on the Gigabyte GA-8N SLI Quad in this highly popular on-line game in which sound is as critical as frame rates. Splinter Cell Chaos Theory has an acceptable loss of 6%, but Wolfenstein Enemy Territory loss is close to 13%. Obviously, if you are a serious gamer, then a dedicated sound card is a requirement and fortunately, the board had two PCI slots available.

While the Realtek ALC850 codec offers acceptable CPU usage and sound for most office applications or internet based flash games, it is not competitive in audio quality with the MSI P4N Diamond or Gigabyte GA-8I955x on-board audio solutions.

We have finalized our expanded audio testing suite and will introduce this in the next review roundup.

    It is an awesome board.

    Thank you for the comments about the sound tests. We will be expanding this test suite greatly in the coming weeks. If you think BF2 has a hit, wait until you see the F.E.A.R. scores with sound effects at maximum. ;->
    However, in order to be consistent we will be testing the latest driver sets for each audio implementation along with adding an X-FI into the mix. The audio drivers within the latest NVIDIA 6.82 platform set are more game friendly than the RealTek versions but you give up some functionality and features for it.

    Gary - don't know if you will see this or not, but it would be interesting to see how the X-Fi series Creative card compares to the BlueGears X-Mystique, which is a highly rated ~$90 audio card available from NewEgg among other sites that has an excellent featureset (of course it lacks the latest EAX that Creative keeps for themselves so they have a reason to sell their wares to gamers, but it has more Dolby-related 5.1 features than the X-Fi series).

    Would be neat to see those two cards compared in "% usage" of CPU during gaming.

    Good Day,

    I have bought several cards the past few weeks including this one and the Chaintech AV-710. I intend to greatly expand the scope of audio testing on the board reviews due to the advances in on-board quality/drivers or the lack of in the nF4 area. I have a hard time understanding why most board manufacturers are shying away from C-Media as their on-board solutions always worked/sounded better than the RealTek AC97 counterparts. In the HD audio area it is a toss up in my opinion but I prefer the SigmaTel codec's on the Intel boards at this time including Intel's software packages. Hopefully I will be able to have the full audio section available in a couple of weeks. The next article series will have a little more information but is not representative of where we will be going in the future.

    I appreciate the comments and suggestions. I welcome anyone to email me if you have concerns or suggestions about our information. Obviously we have a format to adhere to and cannot test every possible hardware/software solution but I am always open to suggestions. :-)

    Oh and dual true-16x PCI-E slots and the passive cooling are both incredibly desireable features. When the AMD version of the board comes out I'll be all over it provided it reviews as well as this one did.
  • Leper Messiah - Thursday, October 27, 2005 - link

    If the AMD version works as well as this one does for intel's, I've got my new mobo picked out. Heat pipe cooling+ 8 phase power= The win! 840EE's at 4.2 might actually give an overclocked X2 a run for its money! :gasp;

    Except that EE's will run MUCH hotter than X2's. This isn't a big deal if you have your own nuclear reactor.

    It was not that bad on this board (a very good description from you), idle temps at 37c, 4.1GHz at 46c according to the bios readings. I believe they were very close as I had a duplicate setup with the MSI P4N in it and you could feel the difference with your hands near the case. We will have thermal tests in the near future.
  • Karaktu - Thursday, October 27, 2005 - link

    One thing I would REALLY like to see added to review articles is the total power consumption of the test setup, both at stock and overclocked settings. There are a couple of power supplies (Coolermaster, Thermaltake) that include attached wattage displays for convenience.

    This would be useful for a number of reasons, not the least of which would be an idea of how much it's going to cost you to run such a rig. ;)

    Hi Joe,

    We have discussed this and it is nice to see a request for it. :-) Hopefully, once I have the test equipment setup then we can include these results in selected articles. You will find this information in the some of the CPU reviews already. We will also start checking thermal readings when a manufacturer introduces new technology onto the board. Asus did this with the eight-phase design and it certainly helped the thermal conditions on the board and with the CPU. This was based on a more subjective review of numbers generated from the bios and monitoring programs (along with overclocking results) which is okay for a high level discussion but is not detailed enough for absolute objective statements.

    Thank you.

    I find it very hard to believe that this is an 8 phase vreg. Simply counting the inductors indicates that it's only a 5 phase. Can you post the VR controller part number so I can see the datasheet?
