Ethernet Performance

The current motherboard test suite includes LAN performance measurements. All of these boards utilize PCI Express controllers with the only difference being the supplier of the core logic.

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 nForce4 Ultra 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, -a 4 - l 256000 - n 30000
On the client side (the motherboard under test), we used the following Command Line:
Ntttcpr - m 4 ,0, -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 Throughput

The Agere ET1310 and NVIDIA on-chip PCI Express LAN solutions exhibit slightly higher throughput, but their CPU utilization is slightly more than the Broadcom solution on the Gigabyte 955x board. The Marvell 88E8053 options on the MSI and Asus boards offer excellent throughput, but at the price of having almost double the CPU utilization of the other solutions.

All standard Ethernet tests were performed with standard frames and the NVIDIA Active Armor suite disabled unless otherwise noted. Gigabit Ethernet supports Jumbo frames as well and will provide a further reduction in CPU overhead.

We added a further test scenario in which ActiveArmor was enabled on the Asus P5N32-SLI Deluxe board via the new 6.82 platform driver set. The throughput numbers increased by almost 3% while the CPU utilization dropped by over 7% with the standard settings enabled in the application. We also enabled Jumbo frames with ActiveArmor resulting in an increase in throughput numbers by 5% while the CPU utilization dropped by over 12%. We will be adding this benchmark testing to our standard test suite along with providing more information regarding the NVIDIA firewall solution in the near future. I highly recommend that if you have a NF4 based board, you should utilize ActiveArmor in its current configuration.

    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?
