Optimus is a technology developed by Nvidia that works only with dedicated graphics cards and Intel processors. It has the advantage of automatically switching between the integrated graphics processor and the dedicated GPU as needed, in order to maximize independence by ensuring that the laptop consumes less power when possible.

Now this technology has existed for some time now but until now, AMD did not offer an equivalent solution. He offered, however, switchable graphics, which can switch between integrated graphics processor and dedicated graphics card but this manually or automatically depending on whether the laptop is running on battery or on AC power.

The goal is again to provide a user-transparent transition between one or the other party graphics. In fact, it is the Catalyst drivers that incorporate profiles per application (including games) while indicating if the notebook should operate on the integrated graphics processor or the dedicated graphics card. The user can also edit this list of application in the pilot if desired.

When the laptop runs on integrated graphics, the dedicated graphics card is put into a state of deep sleep but the bus he remains active so that it can receive instructions and be in working order if necessary, that is ie if the application is launched in the drivers listed as needing the power of the dedicated GPU.
