nForce2 Preview
An anonymous submitter writes "I noticed that a review of NVIDIA's nForce2 chipset has been posted here. From what I can gather the chipset contains two 10/100 ethernet controllers, six USB 2.0 ports, UltraATA133 support, three 1394 ports, five PCI slots, and an integrated GeForce4 MX core including NVIDIA's nView technology and a TV Tuner." Tom's Hardware and NVNews also have looks at it.
Perhaps this has something to do with cooling ... if you look at the pic, the AGP slot is very close to the next PCI slot - perhaps the weight/size of cooling equipment makes the AGP slot impractical for the most powerful graphics chipsets.
This chipset is designed to be used in OEM boards for good performance and enthusiast customers...not servers. I can't think of any legitimate use for *two* ethernet controllers other than in a broader network application (Firewall, for instance).
Perhaps you could use it to make a really stupid sort of bus network for LAN parties using nothing but crossover cables, but that's such a silly idea (performance/configuration issues) that it's probably true...

On the topic of current Nvidia cards:
.plan:
Do not buy a GeForce4-MX for Doom.
Nvidia has really made a mess of the naming conventions here. I always
thought it was bad enough that GF2 was just a speed bumped GF1, while GF3 had
significant architectural improvements over GF2. I expected GF4 to be the
speed bumped GF3, but calling the NV17 GF4-MX really sucks.
GF4-MX will still run Doom properly, but it will be using the NV10 codepath
with only two texture units and no vertex shaders. A GF3 or 8500 will be
much better performers. The GF4-MX may still be the card of choice for many
people depending on pricing, especially considering that many games won't use
four textures and vertex programs, but damn, I wish they had named it
something else.
(all this comes from carmack's
http://webdog.org/plans/1/ )
It seems nvidia is going the same road as intel and sis with their cheap video-on-board motherboard. All of them sucked! Good luck!
Of course, I didn't read the article...
Is there any support, planned or actual, for load balancing the on those dual NICs? Like the old Znyx multiport NICs?
--- Do you believe in the day?
Is it just me, or is NVIDIA trying to it's damndest to piss off Intel? reading the news section on www.nvidia.com, it seems like every 5th sentance states how they are working with AMD to produce this, do that, etc etc. What about Intel? I personally prefer AMDs, but it seems kind of strange that NVIDIA would ignore the larger of the chip manufacturers.
my last sig was too controversial... now, a new and improved useless sig!
Yes, but a plain-old chipset hardly warrants /. space - it's interesting because of the geforce connection.
Bad analogies are like waxing a monkey with a rainbow.
Good/decent expansion support with the PCI, FireWire and USB 2.0 slots/ports... And honestly, onboard NICs aren't THAT bad...
But a GeForce4 MX? Dear god! Any Ti model (that's ANY model, be it GeForce2, 3 or 4) would have been better!
Not that I'm one for integrated graphics anyway.

My question is this: who are they trying to sell this to? Not gamers, since a GeForce4 MX is a stripped down, cheaper version of the real powerhouse GeForce4 TI, which is the new bar for nVidia cards. Obviously, they're not selling this to power users who build their computers piecemeal, because, well... an integrated board by definition defeats that purpose.
Granted, gamers isn't where the money is. The money is in getting someone like Dell or Gateway to use this board in their corporate lease computers. By convincing big manufacturers that the overall cost of making a computer is lower by buying one big all-in-one solution board, they hope to break into new markets.

There you have it. It's a great product, but if you're a typical slashdotter, you're probably not going to care because:
a) nVidia Linux support has been a bit shoddy (IMHO - although the fact that they have drivers at all is a positive note)
b) it's not high end - it's a glorified GeForce2
c) it's integrated, meaning hard to replace if something goes out and not customizable
looked at all three of the articles and darned if i saw more than a listing of the lower end board at $100, which would be about right. The higher end board would be perfect for a lan party rig, or a computer for your stereo, or some such, if the price was right.

It's the preview, not review.
I'm not sure whether to feel juiced about the fact that the nForce has USB 2.0, Ethernet, Firewire, TV Tuner (!!) and a bunch of PCI slots built in automatically, or unhappy that they've paired all of these great features with what amounts to a budget on-chip video card.
There is also a preview article at AnandTech.
See here (one long page for printing) or here 8 pages
Ummm... I still fail to see your logic there..
You probably paid for such a high end card for a very good reason. But you still can change it, and your soundcard, and your OS.
Yes the X-Box is cheap, but not really when you could probably buy an old out-of-date machine being cast out by some company updating there network for about £50 which will be fully upgradeable and may even be more capable as-is.
I also know a few people kicking themselves for having bought them. Yes Halo is a great looking(note LOOKING) game, but then its not gonna be exclusive for all that long. I also object to the size of the thing....hehe

How much better can a chipset make a computer?
When I bought my AMD thunderbird 1.0 gHz and skimped on the motherboard I have always been wondering if maybe I had cheated myself on performance.
What do you think? Would a more expensive motherboard increase my gaming performance enough to justify the cost of a new motherboard?

What? No open AGPx4 (or x8) port for my ATI 8500? ;)
John Maynard Keynes: "When the facts change, I change my mind. What do you do?"
The logic is that I can't "upgrade" my video card without throwing it out, just like an XBox person can throw out their XBox and buy a PC, or an XBox 2, when the time comes. Hell, I'll bet you that this motherboard alone, when it comes out (eventually), will cost as much as an XBox costs.
Sorry but your argument sounds like the argument of a vengeful, spiteful, jealous sideliner. i.e. "HA! I'll bet those stupid Geforce 3 buyers feel dumb now that the Geforce 4 is out!" "I'll bet those Athlon people feel dumb now that the Hammer is out!". Sorry, but I've seen that sort of self-justification far too long in too many message boards. I don't have an XBox (I do too much on my PC to neglect having a good rig), but I can certainly see the allure and logic of it.
The chipset contains 5 PCI slots? I'm impressed. I had to buy a motherboard to get that.
If you aren't part of the solution, there is good money to be made prolonging the problem
Or does anybody else think these are just press releases, not reviews, as listed??
Ummm... The physical slots, and ports are mounted on the motherboard(or through jumpers attached to them), but all of these things need controllers - which will be on the chipset....
Sorry to be pedantic but since you commented...

nVidia's marketing department should be ashamed; the name of this piece of hardware is blatantly misleading. Every other "mx" version of their cards contained the same featureset of it's GeForceX line, but had slower/less memory.
The GeForce4mx, on the other hand, is missing the priciple feature of the GeForce3, that being hardware vertex and pixel shader support. The GeForce4mx is basically a really fast GeForce2. It's a sham.
It screws developers (no longer can we say "GeForce3 and up", we have to qualify by specifically excluding the GeForce4mx). It screws customers by making them think they get a better card than they are. It's just bad all around.
When I talked to an nVidia rep at this year's GDC he acknowledged it's hatefulness and gave the impression that it would be going away shortly. Given the number of these cards I see in stores and this announcement, I'm starting to doubt him.
Note to nVidia: when your marketing department starts screwing developers and customers, we developers stop wanting to support your cards. You've been at the head of the pack for a while now. Crap like this isn't how to stay there.
The current nForce is available in small form factor mobos like the Abit NV7M. I'd be very interested in a tiny version of nForce2.
If you plan to use TwinBank (6GB/sec system bandwidth!) you only need/want two DIMM slots. With video, audio, network, firewire, usb2, etc, all built-in, you hardly need the PCI slots at all.
Fewer components should also mean lower power consumption, which means fewer/slower fans, which means blissful quiet computing. Hopefully.
Also, any word on the rumored Shuttle SS41 yet?
Is it me or are the lackies being hired at Tom's are getting dummer and dummer with time? I don't have time to run down the entire list of inaccuracies and errors in the article, but according to them DDR400 "corresponds to a performance level that SDRAM could only achieve at 400 MHz," and best of all, Nvidia was "Founded in 1997 by a handful of ex-SGI employees."

I know that a lot of people who use traditional Unix workstations like SGIs, Suns and Alphas have always looked down on PC-based systems, even when in recent times the straight-out benchmark speed of PC-based CPUs has roughly equalled or surpassed their 'workstation' counterparts (eg: Athlon XP 2100+ base SpecInt: 720, Sun Blade 1000 900MHz Cu base SpecInt: 470. Athlon base SpecFP: 613, Sun base SpecFP: 629)
The normal response is "a PC might have a fast CPU, but it's connected to slow RAM, slow buses and a slow architecture". Now we have something like the nForce2, which has a dual channel DDR400 memory controller, HyperTransport linking the two components of the chipset, AGP 8x port to a graphics board of your choice, and with an Athlon XP, a 266MHz interface to the CPU. How does a PC-based system stack up against a modern traditional Unix-type workstation like a Sun Blade or SGI Fuel? Is there still some major architectural difference in the design of those systems that still makes them superior to a modern PC design like the nForce2? Assume that all storage is equal, eg: SCSI, to get past IDE vs. SCSI arguments, and you're not using the built in GeForce4 MX core available in the higher-end nForce2 northbridge.

Anyone else notice that this entire 'review' failed to mention if this chipset is for AMD, Pentium 4, or Motorola 68040 processors?
The Tom's Hardware review briefly mentions that it is an AMD board...
- The Alpha 21364 EV7 chip
- 152M transistors
- 1.75MB L2 cache
- 32GB/s interconnect bandwidth (between processors)
- 12.8GB/s of memory bandwidth
Some tasks just need some extra oooomph.

Intel has always been a little hostile to anyone else producing chipsets. I believe with the Pentium IV, Intel has forbidden any third parties from producing chipsets. They went after VIA hard over this issue.
Intel actually licenses the IP necessary to design chipsets for the Pentium IV. The reason that they went after VIA for making a Pentium IV chipset was because VIA didn't go to Intel to get a license for the technology. VIA claimed that when they acquired S3 they also acquired the license to utilize the Pentium IV bus technology (since S3 had a license), and it's been fought out in the courts since then.
Regarding Intel's hostility to third-party chipset makers, that only makes sense. After all, making chipsets for their CPU's is a large portion of Intel's business. By licensing their bus protocols to third parties Intel is making sure that they get a cut of every Pentium 4 chipset sold. They're also raising the costs of competitors chipsets to put them roughly in line with their own. Given the choice in that situation, most people would go with Intel.
Also keep in mind that controlling the chipsets also allows you to control the technology that is used in them. The Rambus memory fiasco is an excellent example of that. Rambus turned out to be an expensive dud on the early Pentium 4 systems, but Intel was contractually obligated to support only Rambus RDRAM memory and no other memory type on the Pentium 4 for a certain period of time. During that time VIA was producing a less expensive and better performing SDRAM-based chipset for the Pentium 4. Most people went for VIA chipsets on their Pentium 4 systems and that was hurting Intel's chipset business, so Intel of course attacked in any way it could.
...except for one little consideration. NVidia has not released full drivers for Linux for the nForce. Are they going to be any better for nForce 2?
I am definitely looking at an nForce 2 based solution to upgrade a Windozer of mine, but this would be a splendid solution for Linux if they had the drivers for it. I hope NVidia gets on the ball this time.
Knowledge is power. Knowledge shared is power multiplied.
Now, if somebody like Jumptec, Ampro, or any of the other embedded CPU board makers would use this! I'd love to have that for my embedded system - fast graphics for all the traces, USB 2.0 for RF control, two Ethernet ports for access...
I wonder if anyone could pursade nVidia to put one of these in there... They have everything else....

But why throw out the entire PC when all you need to replace is the graphics card? Or sound card or even processor? Surely one of the key things about having modular PC's on a tight budget(or even a reasonably generous one at that) is that you can do incremental upgrades to various system components - which although being more expensive in the longer term, allows you to see the benefits of upgrading in the shorter term.
And you dont necessarily have to throw away your old GFX card. Used PC components and consoles have a pretty good used parts market. I let many of my old components go that way if I dont distribute them in my other machines. Though I have hung on to my old consoles.

Why is this article posted to this dinky little uninformative review?
There's a Real Review over at Tom's.
Careful of the gator plugin on the web site linked in the story!
I mean, if they seperated the gpu we could have motherboards without expansion slots. We'd have sockets for cpu, gpu, controller and slots for ram. Who needs anything else. They could probably implement a raid controller in the space the gpu takes up. I suppose motherboard manufacturers wouldn't like it though if you could replace chipsets since the board itself is basically a shell.

As posted many times by many people, the GeForce MX 4 is a GeForce 2 core with a higher clock speed. The only reason it has GeForce and 4 together at all is because the marketters at nVidia knew they could sell more parts.

Ok this board has 6 usb 2.0 ports.

rant
I have more than enough USB ports on the computer that i recently built. Maybe i missed something but whatever happened to the daisy chaining that USB promised when it was first introduced. If I recall correctly, theoretically 128 devices could be connected to a port. When i first heard about the standard i assumed that you wouldn't need a hub to connect devices, I thought that each would have a pass-through.
Did peripheral makers screw up by not including the "pass through"?
I just am tired of all the wires going into my pc. Maybe I never fully jumped on the USB bandwagon, but who needs 6 simultaneous usb connections. (printer,scanner,camera,joystick,dig camera, etc. USB is hot swappable; if you just put 2 on the front most people won't mind unconnecting a camera for a joystick. 4(2 front 2 back) makes some sense to me, front ports are convenient, but why the extra?
This is incorrect. The chipset includes a TV Encoder, i.e. supports "TV Out" - S-Video or composite out to a TV. From the press release:
NVIDIA nForce2 Platform Processors offer a staggering array of features including:
* TV-encoder and HDTV processor for optimal visual quality
It does not include a TV Tuner capable of receiving broadcast TV. You'll have to add one yourself.
BTW, if you're wondering, the HDTV processor simply means it is capable of decoding HDTV-format MPEG2 video. You would still need an HDTV tuner/receiver to get the signal first.
Why would anyone engrave "Elbereth"?
As a matter of fact, the nForce2 is a completely new product that harks on the technology of its predecessor.
Can somebody please give me a definition of "harks"?
Seriously...

I would love to install a new Athlon XP processor on my current motherboard, unfortunately I can't. I have to upgrade my motherboard as well. And I better buy some new, faster memory too.
But why throw out the entire PC when all you need to replace is the graphics card? Or sound card or even processor?

What are you refering to here? The costs related to just upgrading the video card to upgrading a console?
Let's see, upgrading from one console to the other "next-big-hot-thing" costs about $200-$300. Upgrading from one video card to the other "next-big-hot-thing" costs about $300-$400. Where's the cost savings?
And you dont necessarily have to throw away your old GFX card. Used PC components and consoles have a pretty good used parts market. I let many of my old components go that way if I dont distribute them in my other machines. Though I have hung on to my old consoles.
Your video card is COMPLETELY useless without another computer to plug into. The XBox isn't useless just because you get a new console. The XBox doesn't have to be thrown out when you get an XBox2, just like I didn't throw out my N64 when I got the gamecube. Oh yea, and the used Console market is very very very good (better than the used pc components market.)
So basically, you have no argument.
I'm still waiting for Linux drivers that can legally be linked into the kernel. nVidia forces me infringe on the GPL when I use their nvnet driver. It would also be nice to have the nforce drivers in the kernel distribution.

Well, I was a little disapointed to see that it doesn't support Serial ATA (it's not a big deal, but it's something). When will mobos with support for Serial ATA come out?
Another question: do you think a dual CPU mobo with nForce2 chipset be produced/marketed? Because that, and I think many people would agree with me, would be quite sweet (barring the serial ata debacle).
I belong to the ______ generation.
I think nVidia has the right idea by combining EVERYTHING into one package. And we'll finally get onboard video that doesn't suck.
___ alwaysBETA.com - Hey, you've got nothing better to do.
I certainly hope this chipset has better Linux support than the earlier chipset.
I've had experience with a set of three nForce boards used in game servers and have had nothing but trouble. A board that costs a third of the price (the K7S5A) outperforms it. The integrated network controller stops responding if I'm not loading the network interface and refuses to update its ARP table. Graphics isn't worth the price difference - a K7S5A with a *GeForce4MX* would be cheaper and faster than an nForce with the integrated toys.
Given that they are including two NICs with this upcoming chipset, I hope their linux support is above par for this one.
So they decide to put an MX core in as the integrated graphics yet again. Don't they realize this is what crippled the original nForce chipset?
Put a true GF4 (or even a GF3 Ti500) core in there and learn from your mistakes.
Both the nForce and nForce2 were/are great chipsets with one blatant flaw... shitty integrated graphics.
Unless I'm mistaken I did not see anything about a TV tuner to go with this chipset in the Tom's hardware review. I think the other review may have mistaken "TV Out" with "TV Tuner". A TV tuner would be a different kettle of fish, and would be quite noticible on a motherboard, as it requires a faraday cage to protect it from EMR coming from the other components.
I have no pants and I must scream
The problem rarely lays with the features that the chip can provide, one of Australia's largest suppliers currently has a slew of motherboards with chipsets that feature Firewire, Ethernet, 5.1 digital audio channelling and usb2.0.
The problem is manufacturers such as Asus(they aren't alone here), they will use these chips, then brand these desirable features as "Optional" components.
What Optional means is that in the unlikely event that you actually find a motherboard with all the chipsets features(pins on the mobo) enabled(this point alone is the hardest of them all to obtain via a vendor, as they aren't mass-marketable), you are then confronted that you must purchase a side order of special S/PDIF input/output connectors if you managed to obtain the Optional Audio component installed, special firewire connectors if you obtained the optional firewire component and so on and so forth, they specifically state this fact inside the packaging only(obviously for post-purchase viewing only)All this despite the manufacturers gladly parading the features with the word "Optional" on the box, in the feature list and on the web. Often they forget the word optional as well.
To me, if the board doesn't come with it, then it doesn't come with it, simple as that.
If I can't use a stated optional feature then it is clearly not optional at all.
No more of this dirty business where Motherboard manufacturers attempt to trick buyers into products simply because the chipset they use could support a list of features, if they bothered to include the appropriate wiring and mounts.
Thank you for reading my ramble.

What the guy is saying is that the premium you pay for the system being upgradable is much greater than the cost of considering the computer to be upgradeable.
Two years ago I spent $5K on a home PC. Today the only part of the system that is not obsolete is the video card which I replaced about 6 months ago because the old one was not supported by Windows XP (Vendor went out of business)
The nVidia chipset being discussed is targetted at what are likely to be low end machines, but with much better graphics than are ususal for that sector. OK so the graphics are not cutting edge for gamers, but they are probably better than the cards that ship with 90% of PCs today.
The real advantage to me of a system like that is that you could have a complete system in a slimline case without clunky riser cards, something that I might want to have in the living room next to my HiFi.
Now such a system might not be what I would buy for myself as a primary system but I am certain that my 17 month old son is not going to complain about the lack of performance.
If all you need to add is a processor, a case, memory and some disk you could have a complete system for $500 that you could trust to run unattended without fearing it would burn the house down.

FWIW I run an nForce 420 based system, and the integrated sound, ethernet and video all work in Linux. The sound support is somewhat weak (it treats it like a plain old AC97 codec, at least with the current drivers), but it works. This is all with drivers written by and semi-supported by nVidia (err, the sound driver is a slightly modified, open source i810 sound driver). Ohh, and USB works as well, using the standard drivers (can't remember off the top of my head if it's OHCI or UHCI).
Well you'd like to think that the all in one solution would be more efficient on power and heat, but I have an nForce board now and I can tell you that's not the case. I bought the nForce board thinking that it slip inside a 2U case where it could quietly while away the hours as my Linux development machine. I can't exactly tuck it away, because I keep the top off of it to keep it running cooler. The onboard video does run pretty cool and only has a large heatsink (no fan). The processor is another story. It looks like the nForce chipset does not allow a bus disconnect on STPGNT. Basically this means that the Athlon CPU cannot go into power-saving mode at all so it runs at 100% power (read: 100% heat output) at all times. From what I've seen it looks like it doesn't even enable HLT detection.
I've tried to find technical information about the chipset to actually see if there's a way to get around my CPU running balls-to-the-wall all the time, but nVidia isn't exactly just giving that information out apparently.
Apparently I wasn't the only one who wished that Apple would team up with Nvidia.
