Not really, there're also a couple new technologies which should improve SLI performance quite a bit. Talking in general there's gonna be totally new chipset, that shares 680i/780i design, but has improvements and additions.

I will not switch boards again until lower latency DDR3 comes out that is competetively priced.

Why do you think the DDR3 boards are moving so poorly? Because DDR2 boards (the EVGA 780i included) are reasonably priced and overclock like mad. On top of that you can get incredibly good 2 gb kits of DDR2 for around $100.

Integrated PCI-E 2.0 into the NB controller will not improve SLI in the slightest.

The 780i and 790i boards will be differentiated by their ram support and thats about it.

Well, this was posted on OCN in news (source looks reliable) and it looks like a real deal to me:

Quote:
Nvidia also added support for DDR3 memory modules running at 2000 MHz and a little above (overclockers surely know why), but the series of surprises does not stop here. The 790i chipset has some other aces hidden in its sleeves. For instance, the 790i will sport a brand new technology, called Enhanced SLI. The Enhanced SLI is a ****tail of two new features, namely, the PW Shortcut and Broadcast.

The PW Shortcut implementation creates a direct path between the GPUs, via the northbridge chipset. The technology is essential for the performance of the SLI system, but at the same time, it offers additional functionality by taking off the workload from the system CPU. The classical SLI system will transfer data from the first GPU to the CPU via the northbridge chipset to the second GPU.

The Broadcast technology allows the system processor to send information to all GPUs of a system with a single packet, just like a radio antenna. All the delivered performance will have a major drawback: excessive heat. The estimations claim that the chipset will need professional cooling, that will make the MSI CircuPipe technology a joke.

The 790i chip is to be found in the ASUS R.O.G. Striker II Extreme motherboard, which uses hybrid cooling with a water block on the northbridge.

Until I see benches that prove otherwise, I stand by my position.

also considering I've owned no less than 7 sets of SLI cards starting with a pair of 6600GT's over 3 years ago, I've been following SLI development closely.

Nothing I have seen in the last 3 years, 8x8x to 16x16x, newer revision NB controllers NF4, MCP55 and onwards, PCI-E 2.0 support for cards (btw, I am using a PCI-E 2.0 motherboard and 2 PCI-E 2.0 ready video cards. Guess what? Identical bench scores from my older 680i boards).

And Nowyn, its nice that you copied and pasted someone elses comments on the new architecture (and made sure to BOLD them so I would read them), but that in and of itself does not constitute hard numbers.

Look at it this way, if I am wrong and whoever you quoted is right, I'll be happier than you because I intend to stick with SLI on an ongoing basis.

FOR THE LOVE OF QUAD! Nice scores!

I never knew 3dmark06 was a motherboard benchmark =o)

Only thing that tests tell me is that the board can hit 462fsb with nearly 1.65v going to a 45nm cpu.

More thoroughness please!

yup. as a note, with 125 MHz more on cpu, and then the faster ram and ?speed mother board - beats my 780i by ~1000 marks - with LOWER card clocks

(it has been my experience that dual core vs. quad gpu scores are pretty much the same for similar chips on the same clock)

haha. I guess it is when you are trying to get two stubborn cards to cooperate
