Honestly this is far from impressing me, if they really want to impress me they should try going dual, SMP is where i'm at. :)

Well ReMeDy... this Nvidia's chipset is screaming very loudly "Multi proccessing" is what it's best at :), That's what I see.

MichaelD:


<< OK, but they seem to be making a big deal over the fact it has integrated video. It's an MX, for goodness sake! (Not dissing MX owners here...we're just talking. ) Now, if they integrated say a GF2 Ultra or even a GF3, that would be something to get excited about. >>



Fkloster:


<< Will they make a board without intergrated video and sound? >>



The product, as currently specified will satisfy the needs of 85% of the entire PC market, and will probably continue to satisfy those needs for years to come. It has everything Joe Average and his family need in the way of basic functionality.

For the 15% or so that don't want the integrated peripherals they can be disabled. There is an AGP port. For the (maybe) 5% who are still unhappy, other chipsets exist.

When you can satisfy the demands of such a large portion of the market, it's not economical to produce multiple versions of the chipset with and without the integration. Production will take place on a huge scale the economies of scale will nullify any cost benefit of a chipset without the integration.

edit:This chipset signs rambus's death warrant, at least in the consumer marketplace - and people said dual channel DDR would be too complex and too expensive for the mainstream...

Wow, I can't believe some people aren't excited about this. :)

The 4.2GB/sec of memory bandwidth might not mean as much if you're not using the integrated MX since the FSB bandwidth is unchanged (not that the Athlon really needs massive amounts of memory bandwidth), but it makes sense considering the structure of the two controllers:
FSB: 2.1 GB/sec
AGP: 1.06 GB/sec
Hypertransport: .8 GB/sec
= ~4 GB/sec of memory bandwidth that could potentially be used by the &quot;northbridge&quot;...which fits nicely with the 4.2GB/sec of available memory bandwidth. It might be overkill now (I doubt any game or video card uses the full bandwidth of AGP4X, and the IDE/NIC/sound in the southbridge probably won't use too much of the Hypertransport bandwidth), but it's nice to know that the bandwidth is there for the future.

The most impressive thing is the speculative hardware prefetch on the northbridge. It could help a lot with performance...check out this graph. With all the iterations of DDR chipsets for the Athlon (ALi, AMD 760, Via KT266, Sis 735), it's obvious that despite the identical memory bandwidth, the DRAM controller makes a big impact on performance. With the crossbar memory controller and speculative hardware prefetch, it should be a pretty impressive chipset even for those who aren't using the integrated MX.

In the end, this is the first consumer product:
- with hardware prefetch on the northbridge
- with hardware Dolby Digital encoding
- to use AMD's Hypertransport I/O bus

I agree it sounds promising....next stop benchmarks!!!!...lets see real-world performance and get a look at the price. If it is targeted to joe average this board needs to be in the 120 range.

Also any real competition to via is a plus, as it may cause via to remove head from arse and up their quality of their product...Nvidia may release a sh^t load of detonator drivers, but for them at least it is to tweak the product more to gain extra juice. Whereas for Via the drivers are usaully to fix all the bugs that should have been hammered out ahead of release of the product.

I am not a big gamer. I am into cadd design and video application. I look forward to using the onbaord video as well as adding a secodary card to handle my capture, vivo, and tv tuner needs...

How is the memory handled for on-board video? Ie. textures.

Anyways, I've been waiting for an integrated audio/video solution for years. Nice to see someone actually do it.

Hope that it actually works well.

Oh, and according to Tom's Hardware, only ONE driver is needed for the entire mobo (thanks to NVidia's Unified Drivers). Hell yeah, and screw VIA! :D

Maybe we can get some leaked drivers too for increased performance :D

Here's Tom's Review.

I am getting swallowed up by the hype here. nVidia has out-done themselves with the nForce chipset. I'm even excited about their APU! Come this Winter, I think there's a decent chance I'll have a system featuring an nForce420D chipset, a GeForce3 GPU, and a fast AMD Athlon CPU!

<Edit>I agree, the unified driver for the whole shabang kicks a$$!</Edit>

Tom is a copycat, see my signature. :D

I'm keeping my fingers crossed for,

AMD Athlon 4 2.0Ghz + ASUS nForce420D + GeForce3 + 512MB Crucial PC2100 Cas2.5 DDR RAM + WinXP

OK, so who's gonna be the first one to get an nForce board?? :p I'm either gonna get Abit's NV7 (I think that's the name) or Asus's board right here, the ASUS A7N266-V:

**EDIT**

Oh, and another thing. It's stated that the southbridge (communications/multimedia controller) has a built in LAN and Modem controller. Does that mean that the boards will come with headers or something for LAN and Modems connections? I'm new to this whole integrated scene as I have never bought an integrated motherboard before.

I ask, b/c I would gladly get rid of my PCI NIC and Winmodem for a built in version to free up PCI slots.

will nvidia own the world?

I don't know about that, but it's probably still a good time to buy stock!

Gaaa I can't believe they didn't put USB2.0 or Firewire into the southbridge. Geez....

NFS4, Good question!!! I am interested in knowing that as well...

The smaller number of devices in the slots can free up slots, plus the less amount of devices can help airflow and keep temperatures down in the cases...

Well condidering that MS won't have native support for USB 2.0 in XP and there are about five (if that many) USB 2.0 products out right now could be the reason ;) Also, I don't know of many people here with Firewire devices.

Remember, this is an integrated solution, hence Firewire wouldn't be considered in the first place.

Amen to that. :D

Man after reading toms preview, I am really wanting this board. :D

Have a look at this guys....

http://www.penstarsys.com/previews/nvidia/nforce/nforce_2.htm

penstarsys reports a Stream Copy64 score for nForce at 970MB/s for dual channel and 681MB/s for single channel. The 760 chipset is also thrown in there for comparison with a score of 557MB/s. This might seem low for a 760 chipset, so I did a little digging and found this article posted on Aces Hardware:

P4 article

According to the benches here, the 760 chipset DOES indeed score 557MB/s in the Stream Copy64 benchmark. Furthermore the i850 chipset scores 1163MB/s.

So a complete table:

760/PC2100: 557MB/s
i850/PC800: 1163MB/s
nForce 64-bit: 681MB/s
nForce 128bit: 970MB/s


This is almost P4 territory gentlemen. I never thought I would see such a high stream score on the Athlon platform. I hope some sites will publish Cachemem memory latency scores soon. That would complete the picture as far as synthetic benchmarks are concerned.

the duron will fnaly have a great integrated solution to now completely and thoroughly kick the crap out of the celeron and the 810/815 combo. :D

Somebody have me build a system with one of these boards please. ;)

According to Tom's Hardware, this is only a four layer board. This suggests the board will be cheaper to make compared to some other DDR solutions. I hope the cost savings will be passed on to the consumer because I want one.
