Reference Boards are normally quite different from the production boards that will later appear with the Reference Board chipset. While certain component arrangements may be retained from a Reference Board, the board is designed for testing and qualification, and generally not for production. Normally, they are also designed to be tested on the bench, out of any case.



Many, including AnandTech, complained that nForce3-150 was simply out-of-date when it came to integrated features. nForce3-250 definitely does not suffer from that problem. The nF3-250 feature set is as up-to-date as the 150 is not. You could still build an extremely capable system with the nF3-150, but many of the features had to be provided with add-on chips, which increased production costs. nForce3-250 moves from deficient to feature-rich, and competes very well with the best solutions from VIA and SiS. Standard features include 4-drive SATA Raid, 8 USB 2.0/1.1 ports, ATA133 IDE/RAID, AC '97 2.1 6.1 channel audio, and on-chip firewall. The enthusiast version adds on-chip high-speed Gigabit LAN, similar in concept to Intel's CSA. This moves LAN to the chip itself and away from the PCI bus bottleneck.

Fully decked out, nForce3-250 provides features available nowhere else, like on-chip 1Gb Ethernet, on-chip firewall, 4-drive SATA RAID, and both SATA and IDE RAID that can be combined.

    PCI EXPRESS ?

    There's a huge gaffe on the On-Chip Gigabit page. It states that Fast Ethernet runs at "100MB/sec" and Gigabit runs at "1000MB/sec." "MB" is shorthand for mega<i>bytes</i>, not mega<i>bits</i>. Megabits should be abbreviated "Mb."

    Normally I wouldn't be this anally-retentive, but the poor usage leads to another problem later on down the page. The article states that Gigabit Ethernet running at "1000MB/sec" is faster than the PCI bus which runs at "133MB/sec." The PCI rate figure is correct, but the Gigabit figure makes it look like Gigabit is about 8 times faster than the PCI bus itself. <i>It's not!</i> The PCI bus runs at (133Mbytes/sec X 8 bits/byte = ) 1064Mbit/sec, which faster than Gigabit. The article is very misleading in this respect.

    In truth, the PCI bus can almost never reach its peak 133MB/sec rate (usually it's around 100MB/sec) but then again Gigabit can't reach it's peak either.

    Regardless, the article is completely incorrect when it indicates a Gigabit card would overwhelm a PCI bus. This is not true.

    Argh... I keep forgetting that it's 1000Mbps _full duplex_... nVidia are indeed correct, the PCI bus is only half that speed. :-/

    First off: GB is GigaByte. Wesley wrote "GB" more than once while actually referring to Gigabit (bit has lowercase b).

    Next, 1000Mbps is roughly 125MB/s (theoretical peak I expect). 33MHz 32-bit PCI is roughly 133MB/s. I dislike PCI Gb implementations as the next guy, but I'd still like to know how nVidia managed to come up with the half speed figure? Perhaps nVidia's PCI-bus implementation is sub-par? (which is a real issue! Via has struggled with really bad PCI performance for years :-( )

    Finally there's 6-channel audio; What happened with Soundstorm and Dolby encoding implemented in hardware? (I currently use only the SPDIF connectors on my nForce2 and get surround sound both in games and while playing DVDs -- is there no way to get this functionality with Athlon64?)

    Hopefully the next article will shed some light on some of these issues. Cheers! :)

    gigE is awesome and worth it. i dunno about the firewall but eh. 45MB/s network transfers are fun.

    schweet... when is my 16x nforce 250 mobo comming the the mail?
  • klah - Tuesday, March 23, 2004 - link

    hmmm.. seems that last page was slipped in from the November SiS article. weird.

  • Phiro - Tuesday, March 23, 2004 - link

    yeah, the SiS 755FX plug at the end was sort of a red-herring - didn't fit at all with the article, which was soley about Nvidia, it didn't need SiS's recent efforts tacked on the end at the last second.

    A couple things:

    1) to all you nay-sayers about the worth of gigabit ethernet - I thumb my nose at you! Let's not play chicken or the egg games here, let's just usher in new *desired* technology as smoothly as possible - having gigabit ethernet will push me to replace my netgear 10/100 switched hub, not the other way around.

    2) Anandtech, what's with the nvidia ass kissing? When you say things like 'Nvidia assured us.." and "We did test Nvidia's claim... [and we believe it]" - come on, a little healthy doubt is a good thing. Just because they supplied you with a reference nforce3 250 mobo doesn't mean you have to see how far you can stick your tongue up their butt. Honestly, the article felt like it leaned toward Nvidia abit. Believe it or not, you can report on a product without it sounding like some money changes hands or something.

    What's with the SiS 755 crap at the end of the article? Someone didn't proof read, huh? That is also obvious in the spelling errors. Excellent article. Better than recent ones. I do wish that you had been able to include the performance portion, cuz now I'm itching to see them.
    One thing tho, how many people have several gigabit systems at home? I know I will not upgrade any of mine until they are replaced, so it will be awhile. Therefore I am not too excited at this point, especially if the high speed wireless standards work out to high enough throughput to allow real time multi-media transfers. Love the on chip firewall, but Zonealarm is still the only useful application specific solution I know of. Not that I'm an expert, I am far from it, but the Blackice debacle was seen coming long ago.
