nForce4: PCI Express and SLI for Athlon 64

Final Words
nVidia did quite a turnaround with the nForce3-250 chipset family back in April. The nF3-250 updated the much-criticized original nForce3-150 chipset and moved what had been the worst of the Athlon 64 chipsets to the front of the Athlon 64 pack. The plethora of new features that were introduced with nF3-250 have proven to be useful and reliable over the last six months. nVidia also navigated the move to Socket 939 in the nForce3 Ultra version without any glaring problems. The on-chip Ethernet, hardware Firewall, solid PCI/AGP lock, and "any-drive" SATA/IDE RAID have been well received in the market and remain as desirable today as they were 6 months ago.It is not a surprise, then, given the massive updating that went into the nForce3-250 chipsets, to find the nForce4 more evolutionary than revolutionary. The new 4 name is certainly justified by the addition of PCI Express and SLI capabilities, but nForce4 is still underneath the excellent nForce3 Ultra chipset that we have come to trust. Except for PCIe and SLI, the new features generally refine those first seen in nForce3-250, and that is a good thing. The RAID controllers are now faster, more flexible, and even easier to manage than the last generation. The nTune Performance Configuration Utility does more, and does it better, than the previous utility, and 10 USB 2.0 ports must be better than 8. The performance also breaks no new ground, nor did we expect it to. The nForce3-250 was very fast and the nForce4 is just as fast, but not really any faster than the nF3 Ultra at this point.
The major new features, PCI Express and SLI, are the real sizzle here. It is difficult to argue with what appears to be a very successful move by nVidia to PCI Express, even if there is really no current performance advantage that we could find to a PCIe video card compared to the same card in AGP clothes. Certainly, the potential for better performance is there, and nForce4 certainly protects the end-user for a while longer from video card obsolescence.
However, nForce4 is exciting mostly because of the incredible performance potential of SLI, which combines two top nVidia video cards into a monster video performance engine. It's not for everybody - SLI is undeniably expensive - but the prospect of a 40% to 85% leap in the performance of the most demanding games that you can run today will be too much for some enthusiasts to resist. No, you don't absolutely need SLI, but it sure is cool! Consider nForce 4 an evolution and refinement of the progress that nVidia realized with the nForce3 Ultra, and that's a very good thing indeed.

GG putting DOOM3 on the DX9 page.R3MF - Tuesday, October 19, 2004 - link
lol, i have an NF7-S too.somehow, despite all the good things about the NF3 250GB chipset i just wasn't compelled to go and buy an A64 rig, it may have had something to do with an adverse fear of Creative Scabs cards.

#35, you may be right about their driver writers..but they still write better drivers than any other consumer-level audio I've used in quite some time. (Ensoniq had decent drivers in the day, but guess who bought them?)
Now isn't THAT a scary thought?
Granted, I'm currently using soundstorm on my NF7-S, but I dislike the limited hardware 3d channels. I've had usefull sounds in games(like the gun that is shooting at me) be silent, while I hear other sounds like my footsteps, and the other 30 guns around me..

"So any chipset that supports pci-e should handle sli just fine, as long as the mobo maker puts two physical 16x slot connectors, regardless of their actual bandwidth."Negative.
a 1x lane w/ a 16x connector would not be enough bandwidth for the second card.
Yes, 4x is enough for most current games, just like noone currently needs AGP8x.
However, having one video card on a 16x lane and one on a 4x lane is a very screwy setup. What if that second video card temporarily needs the lions share of the bandwidth? Using two 8x lanes w/ 16x connectors seems like a much better way to me, if only because it balances the load between the cards better.

Here's another one, dissapointed about no updated audio sollution. Going from an nForce2 sollution, slapping in an old SB Live card or something doesn't sound that exciting...knitecrow - Tuesday, October 19, 2004 - link
I am not sure how NVIDIA came to the conclusion that audio was not a factor in buying decision. But it is the stupidest thing i have heard.If my memory serves, didn't NVIDIA originally say somewhere that they didn't see a need for audio based on the hardware reviews?
Anyway, the conclusion is all wrong. For those of us building media PC to hook up to an audio receiver, the original soundstorm on nforce2 was a great option.
For gamers who did not want to pay $100 for creative cards, sound storm provided a better solution than your typical mobo audio that didn’t have any DSP.
Many hardware enthusiasts love soundstorm. Anandtech is a hardware enthusiast site. I think it has a role to play in advocating consumer needs. Everyone made such a fuss over AGP/PCI bus locks (a feature that only interests overclockers, a minority) that NVIDIA and VIA had to put locks in.
I have to agree with #34
It does seem a bit draconian to make no mention of it at all. The criticism should be leveled against manufactures when required.
To say the issue has been dealt with or that it is old news, is simply being lazy.
The lack of soundstorm is a big problem. Its real, its relevant and it effects readers of Anandtech.

and nor has any other preview made mention! what parts of the NDA have not expired, and when will they expire are questions i'd like the answer too.either nVidia has an ace up its sleeve, or it has nothing and structured the NDA in such a way that the initial wave of publicity across the web focused on the NF4's good points, and did not dwell on the lack of SS2.
i could forgive nVidia the lack of SS2, but not limiting audio to AC97. i loath Creative Labs gear with a passion, if only cos there drivers appear to be written by a bunch of howling monkeys jumping up and down in a skip full of broken keyboards, i do not want to be forced to buy one!

but why did your preview make [b]NO[/b] mention of audio at all? to the point whereby it seems you are being arm-twisted to avoid the subject entirely?Wesley Fink - Tuesday, October 19, 2004 - link
Audio Comments -nVidia has not had SoundStorm on any nForce3 chipset. This means that for the past year+ SoundStorm has been "missing" on any nVidia chipset for Athlon 64.
We raised this issue for nForce3-150, then for nForce3-250 at http://www.anandtech.com/cpuchipsets/showdoc.aspx?... By now the change in nVidia audio on A64 is only news to those who are still using an nF2 motherboard.
nVidia has hinted that an updated audio solution is possibly in the works, which may come to market as a standalone card. But don't hold your breath. The data we have seen showed SoundStorm had little impact on the buying decision, which is one of the reasons nVidia dropped it for Athlon 64.

i swear the anand data-sheet on the CK8 chipset indicated that the sound would be some variety of high-definition audio, but on checking the link now (via nforcershq) the audio is only listed as just that, audio?
