nForce4 Ultra Roundup: Charting the Mainstream

Ethernet Performance
We have often talked about the throughput advantage of PCI Express compared to PCI and its impact on Gigabit LAN performance. To show you this, the new motherboard test suite includes LAN performance measurements.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:
Nttcps - m 4,0,On the client side (the motherboard under test), we used the following Command Line:-a 4 - l 256000 - n 30000
Nttcpr - m 4,0,At the conclusion of the test, we captured the throughput and CPU utilization figures from the client screen.-a 4 - l 256000 - n 30000
All Ethernet tests were performed with standard frames, but Gigabit Ethernet supports Jumbo frames as well. Jumbo frames 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.

oh...final system will have 4-5 HDs, standard DVD reader/writer along with (most likely) a 6800Ultra or a X800XL...Xenoterranos - Wednesday, July 6, 2005 - link
Anandtech did toy with a listening test a while back (I really don't remember much about it, other than the fact that they should have used Klipsch proMedia Ultra 5.1 speakers...)vijay333 - Wednesday, July 6, 2005 - link
Maybe I missed this info in the article somehow, but could you provide the minimum/recommended PSU wattages for the motherboards? esp the DFI and the Epox. I have a Antec 400W Smartpower PSU right now, but read a few posts on newegg that this might not be enough? Hope I don't need to upgrade this too along with the mobo, cpu and gpu...vijay333 - Wednesday, July 6, 2005 - link

I have a comment about audio -- a topic that most sites ignore.Shouldn't there be a blind listening test?
i mean cpu utilization is fairly useless. If i am listening to mp3s i care more about the quality than cpu utilization.

I stopped reading on page 4 upon discovering the round-up. No explanation needed...Wesley Fink - Wednesday, July 6, 2005 - link
g33k -The DFI was more a control to demonstrate SLI and Ultra performance were the same other than SLI video. Drivers have updated and we retested everything on the DFI as a sanity check. We ran benchmarks and not a full review, but it was hard to ignore the excellent performance.
There is also a comment in our Final Words that the MSI Ultra board should also be considered a winner, since the SLI version was a Gold Editors Choice in the SLI roundup, and the Ultra should perform the same.

Along the same logic though, I'm curious as to why you chose to review the DFI Ultra-D when you reviewed the SLI version of this board earlier as well?.g33k - Tuesday, July 5, 2005 - link
Jeez, read Wesley's comments, he just answered why he did not review, the MSI board. It was already reviewed in the SLI roundup.Wesley Fink - Tuesday, July 5, 2005 - link
"As you can see, none of the onboard audio solutions were quite as low in CPU utilization as the Creative SoundBlaster Live! Chip, which is used on the MSI K8N Neo4 SLI Platinum tested in the nForce4 SLI roundup."Since this is still nF4 we included components tested on all nForce4 boards. The Ultra version of the MSI, BTW, uses the Realtek ALC850 chipset and not the Sound Blaster Live!. The SB Live! is only used on the MSI SLI.
