The nForce4 Family

The nVidia Reference Board was shipped with the nForce4 Ultra chipset. The features of the nForce4 chipset family should be very familiar to nForce3-250 users, since it builds upon the feature set of the nForce3-250 family that was introduced in April. All of the new nForce4 chipsets support 20-lane PCI Express, native Gigabit Ethernet (on-chip), full nVidia RAID features, 10 USB 2.0 ports, nVidia Firewall 2.0, and the new nTune Performance utility. From there, however, the 3 members in the new nForce4 family differ a bit in features depending on the target market for the chipset.



nForce4 - the basic value chipset for 939 and754. This is the chipset that you will likely find in Socket 754 and low-end Socket 939 boards selling for less than $100. The nF4 is targeted at value boards, but it still includes on-chip gigabit Ethernet capabilities, support for 10 USB, full nVidia "any drive" Raid capabilities, support for nVidia Firewall 2.0, and support for the nTune Performance Utility. Four SATA drives are supported at current 1.5GB/s speeds plus four PATA (IDE) devices. The big disadvantage of the vanilla nF4 chipset is that it only supports 800 Hyper Transport. In addition, the HT bus is locked on the basic nF4 to prevent overclocking of the Hyper Transport. This means that the basic nForce4 is not a good choice for the enthusiast, who is better served by the Ultra and SLI chipsets.



nForce4 Ultra - the mainstream nF4 designed for boards that will sell in the $100 to $150 price range. In addition to nF4 features, you will find full support for an unlocked 1000 Hyper Transport, support for 3Gb/s SATA drives, and nVidia's secure networking engine, which is called ActiveArmor.


nForce4 SLI - the high-end version of the nF4 is designed for boards that will sell at $150 or more. The nF4 SLI is the only version to support programmable PCI Express lanes, which allows the use of either a single or dual Video Card. A single GPU is supported by an x16 PCIe slot, which can be reprogrammed to two x8 PCIe slots to support two video cards in SLI mode. All features are, otherwise, the same as nForce4 Ultra.

    According to nVidia's website regarding the nForce 4 SLI, it states that the board will have 20 lanes of PCIe. It also states that there will be 3 PCIe 1x slots. I assume that the SLI board will have the option of using 1 PCIe 16x and 3 PCIe 1x slots, or 2 PCIe 8x slots and 3 PCIe 1x slots. Therefore, there is really no "lack" of PCIe 1x slots on the board. That board pictured was probably just a poor representation of the actual retail board.

    The thing I am curious to know is whether there will be a reasonable amount of standard PCI slots available for use until PCIe cards for sound and whatnot become more prevalent.

    Wesley, now that your done testing the board, if you need someone to take it off your hands I would be willing to take that burden. Reply

    Wesley,

    I'm wondering why the dvd2avi divx 5.1.1 show such close results here. With basically the same machines on hardocp, they show the athlon64 beating Intel's best by HUGE margins (like 20% faster than the 3.6 and almost the same over the 3.4ee)

    http://www.hardocp.com/article.html?art=Njc1LDM=

    You guys showed the same thing no too long ago, but I can't find the article now. The paragraph under the graphs of the A64 winning said Intel lost the last thing they used to win in the benches. The article appears gone? What happened here, why so different from dvd2avi results at hardocp? They used the same divx 5.1.1 so it's not the encoder or the frontend. Heck even the 3500+ dominated the 3.6 and 3.4ee (more than 10%).

    Whatever it is, I think a bit of research needs to be done on what's best for AMD, and what's best for Intel and pit them against each other. Clearly AMD people would run the way hardocp does (though it looks no different than what's used here). While you state you can show whatever you want, perhaps you should be showing the BEST for each platform. Would people really go home and run in a way that makes their cpu look like crap?

    When you're talking about cutting 20% off of encoding, that adds up to a lot of time. I'd argue with the statement about divx 5.1.1 exploiting sse3 and making Intel a usual winner. Hardocp has been using 5.1.1 and A64's kill p4's with it (and have for a long time on their site). Is it AutoGK that throws things out of whack? Does it favor Intel so much that it causes a 20+ percent reversal? If it's truly based on dvd2avi how could it be so far out of whack compared to hardocp's scores? I think your readers would want to know which way to encode the fastest with whichever cpu they choose. Why would people want to know what the middle ground is and lose 20% cpu performance? Maybe Xmpeg for Intel, and pure dvd2avi for AMD?

    The earlier results are on on different test bed with a different video card. If you check out results on the same setup at http://www.anandtech.com/mb/showdoc.aspx?i=2128&am... you will see that the Asus is performing about the same as the other K8T800 boards. It is true that the nVidia nF3 and nF4 perform best with an nVidia card which we have pointed out many times in the past.

    just wanted to make a couple of comments:

    Nvidia's Soundstorm was a result of it's partnership with Microsoft and the Xbox. Since Nvidia is no longer being funded by Microsoft and is no longer involved with Xbox2, there is little reason from Nvidia's viewpoint to continue researching audio.

    I also will state that if you are scared of Creative and you want more powerful audio. Get a freaking Via Envy chip. Those are only $20-$30 with shipping and match the Creative Offerings pretty nicely.

    For all those disappointed with old AC97 codec sound chip on nf4, why not wait for via's K8T890 with better envy sound? (ok it's still not as good as soundstorm but it's better than AC97 right?). K8T890 also should have dual vid cards and also NCQ disk support... (but admittedly lacks ntune style bios extras).

    One thing I want to know is if K8T890 only supports nvidia SLI?? Presume so cause it's branded dual GFX. Would be awesome to be able to double up with less noisy ATI cards though. Also, seem to remember that Alienware's dual card solution was NOT SLI and seemed to produce consistent 90%+ frame rate improvements. Anyone know if/when this is coming out?! If so, 90%+ beats nvidia at their own game (and from a computer 'vendor' - ha!).

    Disappointed that dual vid cards might be limited to nvidia - 6800GTs are good but still prefer ATI and 2 nvidia cards would prob be too noisy for me...

    When will the nTune software be avaiable? NVidia's download site has a page for nTune, but the download link at the bottom still points to the old System Utility. Reply

    Correct me if i'm wrong but this how i see it:

    First check this review:
    http://www.anandtech.com/cpuchipsets/showdoc.aspx?...

    -------------------

    Check the Business Winstone test scores:
    nForce3 => 30.1
    K8T800 => 28.9

    Now this review:
    nForce3 => 30.1
    K8T800 => 26.9

    ---------------------

    Now Multimedia Winstone:
    nForce3 => 37.4
    K8T800 => 36.9

    In this review:
    nForce3 => 36.9
    K8T800 => 33.4

    ---------------------

    This can't be right?
    If the Asus board really performs this bad, then they should have taken another board.

    It's harder to judge about the gaming test since they use a different card. Above that, Geforce cards tend to perform better on a nForce platform. So my guess is to have a fair review they should have used a ATI based card like the X800.

    Second thing they always forget to mention is the Serial ATA driver for the Via board. I mean this can be an important factor.

    I agree with post nr. 69 & 70.

    Lately i'm starting to lose faith in reviews from Anandtech, just like i did with Tomhardware a couple of years ago. Seems like you can't get reliable reviews with the big review sites anymore.

    We will be rewiewing the K8T890 as soon as we receive a retail board. Thus far none have shipped.

    The K8T890 reviews at other sites in September were based on a traveling preview board which VIA did not make available to all of the major review sites.
