780i to bring Hybrid SLI to desktops through AMD chip

Nvidia will bring the ability to flip at will between integrated and discrete graphics cores to the desktop early next year, courtesy of upcoming AMD-oriented chipset the MCP78S. The chipset incorporates a GeForce 8-class DirectX 10, Shader Model 4.0 graphics engine, but it’s also capable of driving a PCI Express 2.0 graphics card connected via the chipset’s 16 PCIe 2.0 lanes, a presentation slide posted by Hexus.net reveals. That’s broadly what most integrated chipsets do, but the MCP78S also supports Hybrid SLI, which allows the user to flip between the two GPUs according to need. Need 3D performance for gaming? Activate the graphics card. The rest of the time: host the system’s graphics on the lower-power integrated GPU. Switching between the two can take place on the fly, unlike past attempts to do this, all of which required a restart. That was enough to put most users off utilitising the option.
