I noticed a discussion on AMDmb forums on this and I thought I'd ask the same question here. Basically, what would you think of a non-Video IGP? Would it be worth buying over 266A and 735? Here's what I think. I think nForce is a great product overall. It's performance, no matter what anyone says, is at worst 3% slower than KT266A. The main place where nForce loses to KT266A is in Gaming. Their AGP controller just can't beat VIA's mature one. True, it does have issues. The memory issue, I think would be easily solved if mobo makers would ditch the 3rd slot so it's simpler to end users (Abit's allready done it on their mATX board) and also if mobo makers added a SuperStability option in the BIOS, everything would be fine. The overclocking, with a AGP Card, is definately an issue, and is very unfortunate and it for some users may be worth ditching nForce because of it. Now on price. I think that the main thing is that it just needs to come down a tad more. I think that unless a user needs RAID, it would be very difficult for a user to take a A7V266-E over an A7N266-E if the A7N266-E was around $160 or so (where the K7N420 Pro is now) while the A7V266-E and Dragon+ are cheapest at $150.

Is nForce for everyone? NO! I think that one main thing must happen, and that is overclocking with an AGP card must be improved, or Abit pull a trick out of their bag, and make an nForce board that has the same feature that SD7 has (PCI locking, which in turn would lock the AGP bus as well). If that were to happen, and a nForce 220 or 420 board were to hit $150 or so, it would be very much worth it. nForce will definately get better, and even if it were to keep the integrated stuff, I think that a new giant has been born with nForce. nVidia is definately here to stay, and one day they may just take VIA's place in the chipset market. We'll now, enough of that.

About a new nForce. It would definately be popular. The removal of the Integrated video should make it handle fsb overclocking better because Ace Hardware's conclusion was that the Int. Video was degrading the signal integrity of the AGP slot and that was the culprit. So, a nForce without video, could be a massive hit, and would considering that it would be an IGP 64(no need for Dual Channels without a vid card to power) based, it would start at KT266a board prices($150 or so), and eventually make its way down to $110-130, and still with the better than Audigy sound and NIC, and overclocking friendly. It would be great, and I would DEFINATELY buy such a chipset for someone that needs a GeForce3 (of course, I'm planning on buying a 420-D anyway), seriously, that could be a big success for the enthusiast. Would nVidia do it?

Probably no. Their whole philosphy is that with all the on-board stuff, it decreases the workload of the CPU (not that we need more CPU power), and not only that, but OEM's aren't dumb. MicronPC is shipping a nForce 420-D system with a GF3 Ti500, and they wouldn't stick with 420-D if a non-video nForce were avialable. They would still be able to market it as nForce, but sales on 420-D would drop even lower. It would be great, and would be a killer.

Now for something I noticed at this thread. This guy posted a link to a store in the uk called VGI Computers. Take a look under Hot news, 5th of January.

<< We have been told about a new version of the Asus A7N266 board that should be available at the end of the month. Known as the A7N266C, it will have Dolby digital 5.1 sound, on board LAN but NO onboard graphics. We have added it to our on line catalog. >>

Now that really intrigued me. nVidia has not given any indication that they allready took the initiative to make a non-video IGP. Asus may or may not have had help. I dunno. As I said in that thread, Asus may be just taking an IGP 64, and simply not running the traces to the back for a Video Port and probably selling it at the price of a non-video IGP. Sure they'll lose money, but Asus will be able to take it. What do you guys think of this? It's kinda sketchy, but that sounds very intriuging and II'd keep an eye out for it. Sorry for rambling on, to sum up. nForce is definately a winner for a good amount of people, but not for everyone. If nVidia makes a couple changes, it will be a hit among the enthusiasts as well.

So what do you think?

Good analysis Athlon4all. Here are some of my thoughts.

First off, an nForce without GeF2MX does two very practical things.

1. Increases overclocking potential a lot, since signaling won't be an issue with AGP (as Johan from Aceshardware mentioned in his review).
2. Brings the price down a lot. Even though nForce has high end sound, integrated NIC, built-in modem, etc., the overall price can still be brought down loads. Remember a couple months back it was reported that Nvidia would be releasing an nForce with GeF3 built-in...but in 12-18 months! It's because it's a very complicated engineering task, and that certainly doesn't bode well for a low cost nForce solution now does it. :)

Bringing the price down on nForce and getting it's overclocking potential equal to the KT266A, etc. will very easily attract a lot more people to nForce boards.

<< We have been told about a new version of the Asus A7N266 board that should be available at the end of the month. Known as the A7N266C, it will have Dolby digital 5.1 sound, on board LAN but NO onboard graphics. We have added it to our on line catalog. >>

If this is true, I'm going to ditch the MSI K7N420 I just got and am going to go with this baby. I don't need GeF2MX built-in, but I need everything else. So a board like the A7N266C is just what I need. Hopefully ASUS won't overprice as they usually do.

If nVidia makes a couple changes, it will be a hit among the enthusiasts as well. So what do you think?

I think you've hit the nail right on the head. Nvidia can penetrate the KT266A/SiS 735/AMD 760 dominated market with a none GeF2MX nForce solution. I'm almost sure it would be a hit. The stability of nForce is also great, my home rig is finally up and running with the MSI K7N420. My brother and I love it. Prime95 has been running for over 2 days so far! :D

I think that if Nvidia really wanted the Nforce to appeal to the enthusiast market then we'd be seeing boards without onboard Video. Nforce boards at this point just cost way too much for the performance to be justified. I think what they should've done was design the chipset with dual channel DDR being the first priority and then integrated coponents taking the backseat. Sure integrated would help for system integraters but it's not really meant much for people like us. I think the fact that they chose AMD should've made this clear as the Athlon, in my opinion was made popular by enthusiasts like us. Sorry if nobody agrees.

NVidia promises 2-way and 4-way interleaving with DDR memory, which could be good. They just don't have very good overall system performance even with the huge memory bandwidth.

Why do people keep on making comments like this? The reason that nForce doesn't shatter KT266A is because the Athlon's 266fsb is limiting it!

<< The stability of nForce is also great, my home rig is finally up and running with the MSI K7N420. My brother and I love it. Prime95 has been running for over 2 days so far! >>

How's it working for ya? I was considering it, but after HardOCP's A7N266-E review, it impressed me so much that I doubt I'll get it now, especially when the A7N266 is same price as K7N420 Pro.

IMO they'll do just that, IIRC they did something smilar with an i815 board a while back. Seeing their prices in general, I don't think they'll loose money on it either.

Dunno about the difficult engineering task. I think they make more money on a GeForce GPU than on the chipset, and they just don't want to cannibalise on the sales of their high end (and profit) GPUs.

Yea, NForce's dual mem performance has been a big disappointment, besides that though it is very competitive.

You do realize that nForce with interleaved DDR does not mean 2x or 4x memory bandwidth but actually less effective latency over the course of time? Athlon4All, you imply that I meant the nForce's interleaving was for more memory bandwidth to the CPU. The 133FSB of the XP and Thunderbird is not too much of a bottleneck as far as overall system performance goes; hardware prefetch depends on excess bandwidth to get a benefit. SIMD can handle every bit of data you can throw at it, too. Memory accesses do not happen instantly, so the more accesses in motion the better chance your data is fetched on time. I don't know everything about CPUs, but I do know enough to know that interleaving the DDR is good for the system.

btw - One big caveat with the nForce for the THUNDERBIRD owners is HARDWARE PREFETCH. They basically have hardware prefetch built into the memory controller. And, yes, it is dependent on excess memory bandwith to work. ;)

If nForce did overclock to 166+FSB then it would be extremely attractive in my opinion. Its current limitations is probably not the AGP port, but rather some type of memory controller issue. The AGP port was singled out by one review to be the culprit to its FSB limitations, when it could have been practically anything thwarting the overclock.

OK guys - can not give you a link, since the article isn't in English, but here is the translation.

A7N266-C and K7N415 from Leadtek will include new chipset from Nvidia - nForce 415. To be presice it is not a new chipset, but new north bridge - IGP 415. Main difference : No Integrated Grpaphics. That will make motherboards $20-$25 cheaper.

2Athlon4all: You're the man.

An nforce without built-in video could be interesting for some folks, yes. I don't know that I would want to lose 128bit twin bank mode though, as stated above the excess bandwidth does have good uses it can be put to and this is an area I think we will see nvidia pay plenty of attention to as the drivers mature.

As for the integrated video being a drag on overclockability, I have my doubts. The AGP on nforce is capable of operating at 100mhz when using the integrated graphics, so there shouldn't be to much trouble making 66mhz available for the port. None of which is an issue for me anyhow, since I'm not an overclocker anyway...
