Nvidia have announced that the MCP78S chipset will give the user the possibility to switch between GPU cores. The new chipset incorporates a GeForce 8-class DirectX 10, Shader Model 4.0 graphics engine, but also has the capability of controlling a PCI Express 2.0 graphics card connected via the chipset’s 16 PCIe 2.0 lanes.
This is not a title of novelty, since this feature is widely supported by most of the integrated chipsets, but the chipset also supports HybridSLI, giving the user complete control over the two GPUs. Should the system need hardcore graphic performance, the user may enable the graphics card, while on average computing the system graphics is hosted on the lower-power integrated GPU. This feature really comes in handy since, unlike the previous versions, GPU switching does not need a computer reboot.
