NVIDIA : Optimus technology

1. nVidia has come up with the OPTIMUS TECHNOLOGY for the mobile PCs ie Laptops, Notebooks etc. This technology selects and switches the graphics processor for an application, depending upon the type of application. It automatically swops between an integrated graphics and the discrete graphic card based upon whether the application running needs a brawny 3D chip, or not. This helps the device in offering improved performance in applications when required, while saving on battery by reducing power drain in applications that can do without 3D support.

2. Notebooks with nVidia technology as on date include Asus UL50Vf, N61Jv, N71Jv notebooks.
