We’ve got few laptops that come with discrete GPUs and a dedicated switch that can be turned on or off as per user’s needs. It’s good to have such a switch since it can help optimizing notebook’s battery life but most notebooks with discrete GPUs are devoid of such a switch, which is why Nvidia has developed Optimus technology that basically does the same thing but is fully automated.
Nvidia’s Optimus Technology will automatically detect user’s current activity and route the load on integrated graphics or a discrete GPU. For instance, surfing the web will make use of the integrated graphics whereas watching HD movies or 3D gaming will result in utilizing GPU’s horsepower.
Nvidia reckons this tech helps to extend battery life by up to 2 times when compared to a similarly configured notebook.
The first notebooks to come with Optimus will be Asus’ UL50Vf, N61Jv, N71Jv, N82Jv, and U30Jc.
