Audio Performance

Since this is the first NVIDIA implementation of HD audio, we tested to see how it compared with HD audio implementations from ATI. For audio testing, we used Rightmark 3D Sound CPU utilization test Version 2.1. This benchmark measures the overhead or CPU utilization required by a codec or hardware audio chip. Since we found that Version 2.1 yields different results from the earlier 1.24, we have only included test results with version 2.1.

Audio Performance - Empty CPU - RightMark 2.1

Audio Performance - 2D Audio - RightMark 2.1

Audio Performance - 3D Audio - RightMark 2.1

None of the onboard audio solutions were quite as low in CPU utilization as the hardware Creative SoundBlaster Live! chip, which we have tested on both AMD and Intel top-end boards from MSI. However, ATI's High Definition Audio on the ADI Soundmax used on the Asus turned in excellent performance in all the utilization tests. Results were in every case almost the same as results from the ATI chipset Asus A85-MVP, which uses the same ADI codec with the ATI Crossfire chipset. Azalia HD is demanding of CPU power, but CPU utilization remained below 5%, even in 3D audio rendering as tested with RightMark 2.1.

It is very important to point out that NVIDIA only provides HD audio for high-end AMD Integrated Graphics solution like this A8N-VM CSM board. There is no current NVIDIA HD option for nForce4 or nForce Dual x16 discrete chipsets for AMD processors. We are happy to see NVIDIA offering HD audio on the GeForce chipsets, and we hope that they will soon offer similar or better solutions for their discrete chipsets.

Ethernet Performance

Asus used the hooks in the 430 Southbridge to provide Gigabit LAN on the A8N-VM. Since this was the first time we had seen the Marvell 88E1111 PHY, we decided to test the performance of the on-board Ethernet.

The Windows 2000 Driver Development Kit (DDK) includes a useful LAN testing utility called NTttcp. We used the NTttcp tool to test Ethernet throughput and the CPU utilization of the various Ethernet Controllers used on the AMD motherboards.

We set up one machine as the server; in this case, an Intel box with an Intel CSA Gigabit LAN connection. Intel CSA has a reputation for providing fast throughput and this seemed a reasonable choice to serve our Gigabit LAN clients. At the server side, we used the following Command Line as suggested by the VIA whitepaper on LAN testing:
Ntttcps -m 4 ,0,‹client IP› -a 4 -l 256000 -n 30000
On the client side (the motherboard under test), we used the following Command Line:
Ntttcpr -m 4 ,0,‹server IP› -a 4 -l 256000 -n 30000
At the conclusion of the test, we captured the throughput and CPU utilization figures from the client screen.

Ethernet Throughput

Ethernet Overhead

As you can clearly see, the Marvel 88E1111 PHY performs about the same as the top PCIe Ethernet Gigabit LAN solutions. True PCIe Gigabit LAN is capable of about 35% faster speed than the PCI Gigabit LAN used on some boards. In practical terms, this won't matter to most users, since high-speed internet barely taxes a 10Mb/s connection. The speed difference may be important if you routinely transfer many large files on a full 1 Gigabit network.

    I have bought two of these, needed to be upgraded to 5.06 to really do anyting with it. Asus customer support comment: Dealer should not sell these board without upgrading them first...

    After many hours of testing and emailing with other users:

    - You can't change FSB. It is fixed at 200. No overclocking possible.
    - You can't use HT as specified. it is only stable at 400 mhz at 8 bits, which reduces bandwidth by factor 5
    - Gigabit does not go above 200mbit

    Revision is 1.01

    I send them back.

    Anand and gang,

    in the followup article you guys plan to do, how about adding a section for mobo performance with value ram and with high $$ ram. This board is a steal and those of us who want to make a very capable budget system are curious as to how this would perform with 'budget ram'.

    ie. I have this mobo, and want to pair it with a 3200 cpu and 1gb value ram.

    Despite the many comments on this Mobo and the number of integrated graphics Mobos based on the Nvidia 6100 series chip showing up, I can't figure out where there is enough need/demand/market for these integrated graphics boards??? It looks like a solution for a non-existent need to me. It looks like Nvidia is trying to create a market segment that doesn't exist??? Very strange.

    I, for one, don't give a rat's left buttock for the integrated graphics.

    I'm building a new LAN party PC on the cheap and wanted to make it small. Trouble is, I don't want to make it proprietary a la Biostar/Shuttle.

    So I opted for the Aspire QPack case with an XFX 6800 GS card.
    I'll use the onboard audio and LAN.

    Trouble is, none of the reviews of these 6100 and 6150 mobos (here or on other web sites) seem to compare the performance of these mobos with the performance of other MicroATX boards. I mean, from a performance perspective, I want to compare the MicroATX boards built from the 6100/6150 chipsets with those MicroATX boards that are built from, say, nForce4 chipsets.

    While I may one day build an HTPC, I'm just not a fan of that yet. Still too early in the game.

    But a small gaming PC with good enough performance to rock some FPSs or RTSs with my buds - now THAT's a compelling app for me.

    Has ANYONE directly compared the performance of Micro-ATX boards made from different chipsets? I've been looking, but still haven't found anything.

    "I'll use the onboard audio and LAN."

    should read:

    "I'll use the onboard audio and LAN of whatever mobo I buy."

    Boards with integrated graphics have the largest market share. You know Intel is the biggest player in VGA, right? All the OEMS (Dell, Gateway, HP etc) want the cheapest board poosible, and not having to plug a vid card into the board is just another way to do that, coupled with the fact that it is one less thing to break.

    The nice thing about these nforce boards, and the radeon xpress, is that they'll at least be able to run vista's eye candy, which previous generation integrated parts will not be able to do.

    Does anyone have a good recommendation for a case for this board? Something small but quiet.
  • frustrated - Friday, December 2, 2005 - link

    Please, please, please try an installation of mythtv of this motherboard and let us know the results. Is driver support available in linux for the different components on this board.

  • Phantronius - Friday, December 2, 2005 - link

    Hey Linux boy, we don't care. Piss off.

    Ignorant. Mythtv is big in the home brew PVR market. I think there would be a lot of interest seeing if this board works well in Linux. An installation of Knoppmyth would only take about 30 minutes.
