Also in response to the PowerXpress technology from AMD, a configuration of similar concept named “Hybrid SLI” was announced on January 7, 2008. The setup consists of an IGP as well as a GPU on MXM module. The IGP would assist the GPU to boost performance when the laptop is plugged to a power socket while the MXM module would be shut down when the laptop was unplugged from power socket to lower overall graphics power consumption.
In the mean time, Hybrid SLI will also be available on desktops, with PCI-E discrete video cards, reports have that twice of the performance can be achieved with a Hybrid SLI capable IGP motherboard and a GeForce 8400 GS video card.
Currently, the hybrid SLI for desktop platform only supports GeForce 8500 GT to be paired with nForce 700 series chipsets and GeForce 8400 GS graphics cards with GeForce Boost feature only. Also, another feature, the HybridPower, is not supported for the nForce 730a.
