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 board offers excellent throughput, but at the price of having almost double the CPU utilization of the other solutions.

All Ethernet tests were performed with standard frames and the NVIDIA Active Armor suite disabled. Gigabit Ethernet supports Jumbo frames as well and will theoretically provide a further reduction in CPU overhead. We have seen test results that show the combination of Active Armor and Jumbo Frames can reduce CPU utilization below 10%, which is very respectable performance for on-chip gigabit LAN.

    WTF?? Man who cares about gaming? As if it matters that u have 10 displays for a game?? This has to be designed to be perfectly suited to multichannel VIZ and Sim, a graphics cluster killer before clusters even took off, AKA where SGI and E&S have played for ever. This could be the final nail in the coffin.... my heart bleeds ;) think about it 4 genlocked quadro’s for 8 edge blended quad buffered channels, this is the sort of thing you drive planetariums and VR centres with *NOT* games.

    Where can I get one ?

    No mention of an (Athlon CK804) driver for the South bridge: http://www.anandtech.com/mb/showdoc.aspx?i=2561&am...">http://www.anandtech.com/mb/showdoc.aspx?i=2561&am...
    Only for the North bridge:
    "System Platform Drivers: NVIDIA nForce4 SLI Intel Edition 7.13"
    Also: was the automated driver installer used, or was a manual "Device Manager driver" install routine required? Due to the mix of the Intel N. bridge and an AMD S. bridge?

    Actually, only the Intel driver set is required. I will post a more detailed response later today. We used the automated installation program and you will find the Intel MCP is just a subset of the AMD CK804. I have actually used the Intel IDE drivers on my Nforce 4 board as an example.

    one 2405FPW and two 1704FPV's.

    and the answer is..................

    Email me and I will setup a test configuration for you as I will have that same monitor delivered next week.

    I couldnt find the link in order to download the BF2 AT demo, so I can benchmark myself.
    Anyone found it?

    Nice review, BTW, Hope Nvidia support this board in future drivers just to see 4 Video Cards Benches.
    BTW, I wouldnt buy this board, it isnt available for the best Gaming Processor.

    It's still "beta" from my perspective, and it hasn't been published. My next article with benchmarks will hopefully include the demo and other required files for running the BF2 benchmark, but just FYI, it isn't meant for non-technical types. You'll have to edit a batch file, and it doesn't automatically set BF2 settings (other than resolution) - it just runs with whatever settings BF2 is currently using. Stay tuned....

    Good stuff on adding to the range of games used for benchmarking, and a most excellent choice in BF2 as AT reviews have been lacking in benchmarks using FPS games lately. Adding a seventh FPS title when there are none from any other genre (except Aquamark 3 which is dubious at best as a representative sim) was a great idea as FPS games are all anyone plays at AT. If the recently released Serious Sam 2 is as fun as the two episodes of the original Serious Sam, it might be worth adding that too.

    But seriously, whilst taking the time to add BF2 to the benchmark suite is probably a good idea as it is very popular, you really should consider games other than what you like-- such as racing, flight/space-sims, above-view RPG, RTS, etc. It's no wonder the benchmarks are all so predictable with the main difference between gfx-cards being OpenGL and Direct3D games, when all the games are basically displaying the same kind of scenes.

    I actually ran benchmarks on Nascar SimRacing (Daytona on four monitors is incredible), LOMAC, Falcon 4- Allied Force, GTR, and Call of Duty 2. We firmly believe the standard benchmarks need some additions to represent the overall gaming experience. You will see some of these results (plus a couple of RTS/RPG) shortly in the next "SLI x16" review. As noted in our sound test we will greatly expand the information provided for on-board solutions shortly to also include the new Dolby Master Studio suites shipping with the SigmaTel 922x and Realtek 882m audio options. Once this board is released for production we will do a complete follow-up that will concentrate on multiple-monitor usage.
