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.

    Gary, I got one of the first production runs of this board and I smelled something burning on the first post. I got it to work, but mobo temps were 46-48C. my friend got the same board a few weeks later in an almost identical setup (P43.46EE, dual Quadro FX-3400's, PC P&C 850 PSU) and got 28C mobo, and 29C (idle on the CPUw/Zalman 9500 cooler). So I RMA'd it, and am hoping for similar results. It should be back any day now and I'm hoping they replaced it. Asus forums list many unhappy campers having all sorts of Bios issues. Which Bios are you using now(212 maybe?) Also, I was disappointed that there are only 5 internal sata ports since I use 9 hard drives. I've been looking into using a Sil Image 5X1 port multiplier with a 4 bay esata enclosure from either Addonics or Cool Drives to get a RAID 0X4 on the Sil 3132 with my 4 WD740 Raptors for video capture/editing. Do you know anything about setting up an esata RAID? Thanks

    Thanks for the reply Gary, dont bust a gut though, 1920x1440 is really good enough :)

    Im just welcoming the recognition that people do use high res to do normal things like play games on (shock horror).

    Ive always found it strange that Anandtech reports on so much cutting edge hardware in the cpu, mobo and video areas, the bread and butter of a good review site, but seemed to ignore people with high end monitors in test results - at least you are putting that right now, thank you again.

    Hooray! a reviewer that benchmarks games up to high end video resolutions! Thank you thank you!!

    My own resolution of 1920x1200 wasnt mentioned but I got the picture from what you did cover, thank you again- The other Anand reviewers seem to think theres no life after 1600x1200. (but there is :¬) )

    Nice one

    Hi,

    The review results will depend upon the monitor's capability during testing (several of my monitor's only go to 1600x1200 or 1280x1024). Also, please realize that a large majority of readers have 19" LCDs that only support up to 1280x1024. This is why we standardized on this resolution recently. However, we will start providing higher resolution benchmarks depending upon the hardware being reviewed (performance oriented boards) and time allowances. This is based upon the fact that the next step up for most buyers will be the 1600x1200 ~ 1920x1200 capable monitors.

    The higher end monitor's I have for testing do not support the 1920x1200 format. They support the 1920x1440 and up resolutions. However, that should change in the next month or so hopefully. ;-)

    I appreciate the comments and hopefully we can get you and others some 1920x1200 benchmarks in the near future.

    Thanks!

    As the owner of a P5ND2-SLI-Deluxe I have to say the C19 chipset gets WAY too hot. Not to mention the horrible stability of the BIOS. There has been Many complaints from ASUS owners about these issues. Another issue as of late has been power supplies blowing. I personally experience a 3 day old 500W Aspire power supply blowing, and after flashing the BIOS the entire system dying.

    I wonder about the stability of the NVIDIA chipset and how it will hold up in the long run. I would have liked to see a comparison against the P5WD2-Premium.
  • Gary Key - Saturday, October 29, 2005 - link

    I have read some of the horror stories about the P5ND2-SLI-Deluxe and agree about the thermal issues among others with the A2 stepping of the C19. The A3 and up steppings are better in this regard and the new board layout is significantly more robust than the P5ND2 series. I believe Asus realized their errors from several product releases lately (I went to Intel boards after an earlier issue with Asus) and are in the process of correcting them. This board has restored my faith in their new product lineup. This bios we tested with (0047) has been wonderful from both a stability and performance viewpoint. I personally use OCZ or PC Power and Cooling power supplies and have never had an issue with any board, good or bad. I did not have the P5WD2 to test against but I do have the P5LD2 now. :->

    Hey Gary,

    Thanks for taking the time to write back. Based on your article and statements here I am going to contact my online retailer who is processing my RMA and tell them to just issue a credit and I will purchase the P5N32-SLI instead. Don't worry i won't hold you responsible for my decision :-)

    I just figured it couldn't be any worse than the last board. Hopefully they fixed the things that were issues with the P5ND2-SLI Deluxe.

    One last question, when will this be available, have you heard anything yet? All the online retailers are saying Pre-Order.

    Good Day,

    I bought a couple of boards from NewEgg last week but I noticed this morning they are out of them. I will send them a message and see when their next batch is in. When you receive the board please email me and we can discuss specifics on the board and bios. I really think you will be pleased with this board. If not, please post your issues. I would appreciate another viewpoint or opinion on the board.

    Hi Gary,

    Any word on why the boards all disapeared? Seems that No one has them anymore.
  • Gary Key - Wednesday, November 2, 2005 - link

    Good Day,

    We spoke with Asus tonight. The second production run of boards was slightly delayed due to a couple of minor hardware changes on the board that should not affect performance. They changed resistors in a couple of areas apparently. However, Asus will provide us a new board for testing to ensure results are indicative of the review board results. The next production run of boards should arrive within 7 business days according to our sources. I will post an update to the article if there are any changes with this new release.

    Thanks....
