NVIDIA nForce 980a SLI Reference Platform Motherboard Pictured

[btarunr]

It's only early days though... surely someone will implement a 980a SLI w/IGP?

It's already there like I said, you have a number of 780a SLI boards that have the IGP available, and these motherboards support every AM2/2+/3 processor you can think of. So there's no point in waiting for a 980a with IGP.

Do these chip-sets get 'crippled' (compromised in performance) when the IGP enters the picture? E.g...
Would the 790GX and 980/780aSLI+IGP merely have less PCI-e lines because some are used by the MGPU, or is there more to it than that?

if there is, can you detail the compromises for both platforms? Assuming there's none or the compromises have the same hit 'performance-wise'......
Which is the better performer all-round, once GPU performance advantages are 'masked'..

Reduced number of PCI-E lanes don't necessarily cripple the IGPs. These IGPs don't need an x16 link to work to their full-potential, not even x8 for that matter.

OMG that's just plain bizarre....

But true, and NVIDIA is good at doing it. Rebranding worked very well in selling GeForce 9800 GT and GeForce GTS 250.

That's precisely what I want; top-notch IGP for HTPC/PVR, but the 'potential' for top-notch workstation/gaming machine down-the-track....

By "GeForce 8300" you're referring to the actual on-board GPU, not the chip-set? So the 790GX's MGPU has been verified as better 'all-round', k thanks...
I wonder if AMD/ATi software is still pretty shite` in GNU/Linux? I always had less problems with nVidia....

I'm talking about GeForce 8300 MCP (the chipset), not GeForce 8300 (the IGP). NVIDIA chooses to call it an "mGPU", which abbreviates "motherboard GPU", not "mobile GPU". It's a monolithic chipset. If you don't need to use discrete graphics, you don't need a 780a SLI or 980a SLI. This chipset packs the same IGP.

With Linux, I recommend sticking to NVIDIA. Their Linux driver support is outstanding. A slightly faster IGP won't mean much in Linux anyway.

Understood, if it's purely a certification and the IGP/non-IGP features are the same, why wait!

No I was wondering if IGP implementations of these chip-sets are different to non-IGP implementations in areas other than graphics.

No I may need discrete graphics at some point, but thanks for the suggestion.

Interesting to note, thanks

They're not, as far as their feature-sets go. Whatever differences that may exist, may be brought in by the motherboard manufacturer. Not a big deal.

And GeForce 8300 also offers you a PCI-E x16 slot just for that.

Oh you mean their chip-sets that offer IGP (mGPU's), yeah they're the only ones I'm looking at now...
But don't their range of mGPU's have most of the same features as their range of MCP's? (except for the SLI etc)
I hope so.....

Yes, they're physically the same chip. It's codenamed MCP72, and is implemented in different ways to draw out different SKUs. Hope this gives you an idea:

Do you see the genius of the design from a business standpoint? The rest of the feature-set is nearly the same. MCP82 claims to have an NVIDIA-labeled version of the Advanced Clock Calibration feature, though physically, the MCP has nothing extra added to enable the feature.

ATI works well in Linux these days as well. It's not like the old days. Support for ATI has grown in leaps and bounds over the past 2 years.

Oh this fully clears things up now thanks!

I wonder if the AMD chip-sets compare well feature-set wise to the 780a?
i.e. Do they have the same sort of bridge chip allowing for a lot more expandability with discrete cards, among other MCP features...

It looks like they'll have even more of an edge with the IGP soon now...

But I'm not so sure about other areas...

Yes, the 790FX does. It doesn't have an IGP, and you wouldn't need one anyway.

 

[jalyst]

So the 780A and 790FX are a close match, except that the FX never has motherboards implemented with IGP whereas the 780A sometimes does.
That rules out the FX then because I want IGP from the outset, plus 780A is avail as 790I which support Intel 775, which gives it a slight edge again in-terms of CPU performance.

 

[btarunr]

nForce 750/780/790 Intel series chipset has no IGP.

And I don't see how 780a SLI has "a slight edge again in-terms of CPU performance" because 790i supports Intel 775. That's a completely different chipset.

I thought the Intel series is more or less the same as the AMD series aside from the CPU micro-architecture they support, & hence there are mobo's available with IGP.
I thought this had been previously mentioned, sorry, my mistake...
