From enthusiast to low-end, all new NVIDIA chipsets will feature an enabled integrated graphics core

In conjunction with the Consumer Electronics Show in Las Vegas, NVIDIA launched its NVIDIA Hybrid SLI technology along with its newest chipset. Hybrid SLI is NVIDIA’s first foray into visual computing.

NVIDIA’s Hybrid SLI links NVIDIA integrated graphics chipsets with NVIDIA discrete GPUs, allowing them to work together. The company claims that the new technology lowers power consumption and improves performance.

NVIDIA’s announcement of Hybrid SLI also indicates a major shift in the company’s chipset-feature policy. NVIDIA chipsets with integrated graphics processors (IGP) have traditionally been available only in the lower segment of the market. NVIDIA now decided that all of its new chipsets, low and high-end alike, will come with IGP. 

Of course most core logic includes an integrated graphics processor, albeit disabled. 

Two fundamental components make up Hybrid SLI: HybridPower and GeForce Boost. HybridPower, as the name indicates, is the power-consumption reducing aspect of the technology. It allows for systems to completely turn off discrete graphics cards when their high-functionality is not needed. Instead, the chipset’s integrated graphics takes over.

In order to use Hybrid power, the system must include an NVIDIA IGP and a discrete NVIDIA video card. Under HybridPower, users connect their display to the motherboards graphics outputs. When users require the use of their discrete GPU, the frame buffer contents for the discrete graphics cards are copied over to the integrated graphics processor’s frame buffer. NVIDIA asserts that the second generation PCI specification provides enough bandwidth.

Latency is considered a "non-issue," claims NVIDIA spokesman. 

GeForce Boost combines the power of the IGP -- which NVIDIA calls the mGPU) and the discrete GPU (dGPU) to improve performance. NVDIA told the press that this technology is meant for low-end or mid-range PCs. In fact, the company states that this feature could be detrimental to the performance of high-end PCs.

NVIDIA Hybrid SLI is currently a Windows Vista exclusive.

NVIDIA Hybrid SLI technology will be incorporated into a wide variety of graphics and motherboard desktop and notebook products that the Company is rolling out for both AMD and Intel desktop and notebook computing platforms throughout 2008.

In addition to announcing hybrid SLI, NVIDIA also announced its new nForce 780a chipset.  Naturally, one of the newest features is Hybrid SLI support. In addition, all chipset versions now have embedded GPUs. Currently, the nForce 780a is being launched for AMD processors.

The new chipset supports AMD’s newest HyperTransport 3 link interconnect, and offers 32 PCI Express lanes via an NVIDIA nForce 200 chip.

The nForce 200 comes with a couple of notable features. One of them is a Posted Write Shortcut, which NVIDIA says allows data from one graphics card to be passed directly to other graphics cards without having the data to be sent back through the CPU. The feature is said to improve SLI scaling performance.

As can be expected, the chipset is also ESA certified and supports 3-way SLI.

since when doesnt nvidia support multiple monitors. just set up a pc to run dual monitors the other day. works with their igp and dedicated cards together as well

SLI does not allow the use of dual monitors.

People have gotten around this by writing scripts to enable and disable SLI. They just enable SLI for gaming, since very few games support multiple monitors anyway.

Others use a third cheap non-nVidia PCI video card to run the other monitors off of.

Have you tried any of these "solutions"? Not ideal, but better than not being able to use a second monitor, which I couldn't live without. SLI just doesn't seem worth it's headaches to me.

I'm not sure, but just because it says "Hybrid SLI", it might be completely unrelated to their "real" SLI technology. Especially since it's (hybrid power) only using one or the other GPU.
