NVidia Announces Hybrid SLI Technology

We are all dreaming of a notebook which could deliver stunning 3D rendering and video performance while providing an extended battery lifetime. Some might call it utopia, but it seems that NVidia is working hard to bring a solution to the market.
Most of the mobile GPUs drain power even for rendering 2D while an integrated graphics processor (IGP) will deliver the same level of performance while consuming less energy. By releasing its Hybrid SLI Technology, NVidia intends to bring faster mobility video and 3D performance while cutting power consumption. To achieve such a goal, NVidia intends to offer a platform featuring both an integrated graphics processor (IGP) and a discrete graphics processing unit (GPU). In power saving mode, the discrete GPU is simply switched off on-the-fly, while the IGP will assist the GPU when the user will run applications, such as games, turning graphic units to the performance mode.
The SLI is usually a power consuming graphic solution, but applied to notebook and by associating an IGP and a discrete GPU it could well be the solution for an all-in-one graphic unit without compromising performance and battery lifetime.
