NVIDIA 780a: Integrated Graphics and SLI in One

Final Words
NVIDIA's chipsets have almost always been pretty decent (if not excellent with the nForce4 for AMD), their only issues were usually price and a lack of any compelling features to justify the added cost. SLI was always the biggest selling point of NVIDIA's platforms but with the nForce 780a (and its new lineup of chipsets in general), NVIDIA is attempting to bring more value to the table.
Honestly the biggest attraction to the nForce 780a SLI platform is its support for HybridPower, which will finally allow gamers to build machines that are both high performance and are efficient on power usage. Thankfully you aren't limited to the 780a for HybridPower support as these motherboards won't come cheap. Our ASUS M3N-HT Deluxe board will carry an introductory price of $249, something we are not used to seeing in the current AMD market sector.
Whether or not this price tag is worth the premium over the nForce 750a SLI boards is up for debate. It's not really in our opinion as we do not believe the current AMD processor series is capable of the required computational power needed to support 3-way SLI or Quad SLI configurations. This is not a knock against NVIDIA as AMD has the same problem with Quad CrossFire; it just reflects the current state of the processor offerings from AMD.
HybridPower is clearly in its infancy, the lack of dual-link DVI support from the mGPU means that owners of 30" displays can't enjoy the benefits until the next generation of NVIDIA chipsets come out. We would like to see eventual automated switching between HybridPower modes, not to mention a reduction in switch time for multi-GPU setups, but we'll take what we can get as a starting point. The list of GPUs that support HybridPower will hopefully continue to grow as NVIDIA would be doing its customer base a disservice by reserving the feature for only its highest end graphics cards.
Then there's the plain fact that what we're looking at here is an expensive Socket-AM2+ chipset, and while AMD can be competitive at lower price points, at the very high end of the market there's simply no reason to go with anything non-Intel right now. With Intel's G45 chipset due out later this summer, we would much rather see an Intel solution from NVIDIA shipped quickly as the combination of a mGPU with H.264 decode acceleration and HybridPower could be enough to actually make NVIDIA's platforms competitive in the Intel space.
Looking to the future, we wonder what will happen to NVIDIA's chipset business. Giving every chipset integrated graphics is a good move, but is it possible that it is too little, too late? Nehalem will begin shipping this year and next year we should start to see models with integrated graphics, leaving NVIDIA with SLI as the only thing it has to bring to the table once again. Losing on the integrated graphics performance front to AMD is also troublesome. Surpassing Intel's IGP performance is nothing to crow about for a GPU manufacturer; it's the competing GPU manufacturers that you have to beat, and here NVIDIA falls short. We want to see NVIDIA raising the bar for mGPU performance relative to AMD, not lowering it.

Maybe I'm the only one, but I'm so sick of every new PC component having a global warming psychotic power consumption "feature set", as if any of we end users actually give a d-a- you know what.Heck, maybe I'm lone gunman here, but it really makes me sick, over and over again, as if I'd buy their piece of crap because they have some wattage bean counter going gaga about their lower power requirements.
Hey, here's an idea. STOP GAMING, lower yer rezz, use a tiny 13 inch monitor, and put monitor sleep mode to kick on in one minute.
Better yet, shut your system off, you're wasting the earth, and get outside for heat from the sun or put on a wool sweater, or dunk ter head in the creek if you're too warm.
Who are they fooling ? They're pushing 1,000 watt PS's, then we have to hear this beanny watt counter crud. Yeah, right after the Q6600, 4 HD's, 2 DVD's, memory card readers, dual monitor outputs, ohhh.. and make sure you got a 700 watt plus supergigajiggawatt or she might not run.....
I for one would just like to say, to noone and nobody in particular, go take a green time out.
PS- this article is no more or less green than any other, so it isn't a target. I guess it's clear this is a power surge and perhaps an overload. Well, good!

You are absolutely right, especially the application of this technology to notebooks, which is pure insanity. Why would I care if my laptop could switch from discrete to integrated GPU to save battery power and provide me another hour or so of use? I am trying to destroy the earth so I want as little battery life as possible so I can plug it in and use more resources.As for desktops, those crazy tree-huggers want you to use less power so that your systems run more efficient and PUT OUT LESS HEAT. This would be a complete waste for those who dropped several hundred dollars for water-cooling and giant, ridiculous, circus clown heatsinks. This isn't even mentioning the enviro-psychos who like to use their computer as a floor heater in winter.
How about you take your finger out of your nose because it is clearly in too far and blocking your brain from releasing any common sense.

Why stop at that, you need the wind up power notebook, like the ones selling for the 3rd world. No plugging in and no charging any battery except by turning the crank handle.If you're gaming on a battery, it's not just your finger up your nose, but likely your neighbors as well, to hold it up so high. Where are you that you cannot plug in ... up in that airplane ... saving all that jet fuel ?... or did you drive your Yugo to some way out park to hack, away from civilization, also an energy saver, no doubt. Have fun disposing of the polluting battery, too.
Desktops: If your system is putting out so much heat that you need to run a refrigerator to "cool just the system down", you certainly are not "saving" any power either.. DUH.
Gigantic heatsinks (and their gargantuan fans)are power-hungry users trying to crank out the last bit of mhz, often with voltage increases, huh ... DUH. Maybe the jet engine they replaced was a cheap sleeve bearing, but they didn't "save power".
Not sure exactly what the donkey you were trying to say, since you didn't make any sense, but then, that's what it's all about, huh. Preening your green self while wildly flailing about and praising the gigantic power (savings ? lol ) drain you are, anyway - while firing up the 250 watt triple 3d sli maxxed super whomper game.
I think if you had any common sense, you'd "get it".

Why on is ESA only available on the highest end model? Nvidia wants the industry to adopt and implement it into their hardware but won't even put it into their own stuff?crimsonson - Tuesday, May 6, 2008 - link
I don't understand why so many pages and charts are devoted to pure performance for motherboards. Unless there is physical flaw or bad drivers, performance between these motherboards are normally next to nil!I understand stability, overclocking, and power consumption. But looking at these charts a lot of them are minuscule difference that often can be explained by settings, other components or bad drivers. I am not saying bench testing are not useful. But I don't think it is necessary to view dozens of charts with no or little difference. In fact, it would make more sense to go in to details where there is a significant difference. I think your attention to detail gets the best of you :D

In general I do think you guys do awesome work.

Right. The benchmarks are not that interesting, and also which IGP runs which game at how many fps more or less is pretty uninteresting - as if the world had only gamers.As much as I like the image quality provided by Nvidia products, they're still a no-go if you want open source drivers - and here is much room for improvement. I won't buy (nor sell) any of them unless they follow the good examples of Intel and ATI/AMD.
So my next mb - which will definitely have an IGP again - will be of the other mentioned makers, depending on whether I need an AMD or an Intel CPU next time.

I have to use the restricted drivers on both my desktop (discrete NVIDIA) and laptop (discrete ATi) in Ubuntu.And I've never understood the point of windows that wobble.

Tru, I love not having to install any drivers for compiz-fusion on my Intel G31 system. It actually runs it better than my 6150 AMD system.But, under load with movies and compiz and other stuff graphics wise running, the 6150 doesn't crap out as much.
Good chipset, waiting for Intel's version. I have been an AMD person for a long time, but, for $70 a 2ghz Pentium Allendale works great for me.
WTB a gen 2 Shuttle XPC in silver with either the G45 or Intel's. 3ghz Wolfdale will do nicely.

BTW: tried movies (MythTV) together with Compiz, and that really didn't look nice, even on my 6150/430 Nvidia. Only after switching off most or all desktop effects, the picture became more stable...
