Ethernet Performance

The current motherboard test suite includes LAN performance measurements. All of these boards utilize PCI or PCI Express based 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 Intel motherboards.

We set up one machine as the server; in this test, an Intel system with an Intel CSA Gigabit LAN connection. Intel CSA has a reputation for providing fast throughput and is a logical choice for our Gigabit LAN server.

On the server side, we used the following Command Line as suggested by the VIA whitepaper on LAN testing:
Ntttcpr -m 4,0,‹server IP› -a 4 -l 256000 -n 30000
On the client side (the motherboard under test), we used the following Command Line:
Ntttcps -m 4,0,‹client 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. Our NTttcp test represents the absolute best throughput scenario for our network controllers and will rarely be duplicated under normal usage patterns across an office or home LAN. We decided to create an application test across that would represent typical usage patterns in a home Gigabit and 10/100 network setup. Unfortunately, we have not been successful over the course of the past couple of months in creating a test that is repeatable or does not contain issues brought on by the Vista operating system we discussed in our last article.

Both the CPU utilization and throughput performance favors the Realtek Gigabit controllers with the Gigabyte implementation offering the best combination. However, the differences are slight and will not be noticed under normal operating circumstances.

    Sad how an AMD 7050 board can be had for $80, $40 cheaper with the same features. It is the premium you pay for having dvi.

    Oddly enough too is that the Gigabyte board you quote doesn't use all solid caps yet the lower end board does. And of course, they didn't bother with solid caps on their new AMD boards period, cause "AMD is second tier."

    Preposterous!! Why do they even bother making this junk without DVI. More and more I find that I don't want a leet board that overclocks 100 Mhz higher but a stable board with the right features. -sigh- Reply

    and on top of it, these igp's are not suited well for gaming or videos,,, (the two applications where you may not notice the difference between a digital and analog interface), so they will be used for text/office work... an application where the discrepancies in the user-experience of analog vs digital interfaces with an LCD are undeniable.

    again, great article.,, but in the end, I sort of wonder why waste ur time exploring these boards when your time is better spent on solutions that deserve our money?

    I think both of those G33 + SDVO models launched long after Gary had started work on this uATX stuff. Good to see that some people are including the necessary chip, as uATX without DVI is simply unacceptable. Unfortunately, testing some of this stuff takes a lot more time than we would like. We're working to address that, however. Reply

    I would love to see a review of motherboards with igp
    that can be converted to raid servers by using the lone
    pcie 16x slot.

    Have fun,

    I'm doing exactly what you mention with an Intel DG965RY. I have an Areca ARC-1210 fitted in there with 3 320GB WD Caviar SE16s in RAID 5. Reply
