It is true that MUX-based hardware video is of higher performance overall - but the MUX-less design is more power-efficient and cheaper to implement - making it suitable not only for low-end consumer sysetms (Inspirons) but also business-class systems where high the highest level of video performance is rarely (if ever) needed.With extended desktop mode, you can get a larger Windows* desktop area spanning multiple displays. The AMD GPU is called into use when higher performance is needed (or specified, since you can do that with the Catalyst Control Center). It is the driver set that controls the distribution of GPU load between the two GPUs - normally only the Intel GPU is active. ALL video data - even if it is processed by the AMD GPU - runs through the Intel GPU aboard the CPU, so the Intel GPU will always show active to Windows and most applications. The Latitude uses a MUXless, software controlled video system - only the Intel GPU has a hardware connection to the display panel.

The Alienware uses a true hardware-switching video system - both GPUs have a hardware connection to the screen (this is called a multiplexer, or MUX design). In this case, click “Configure” in the dialog box to select the appropriate GPU. For applications that do not have an assigned GPU, a message dialog box may appear prompting you to select one. When applications are started, they run on their assigned GPUs.

Click the GPU selection button next to the application to select the appropriate GPU.

Only one application can appear in the “Other Applications” list at a time.

If it is not listed, click “Browse” in the “Other Applications” area to browse for and select the application it is added to the list. Check that the application for which you want to assign a GPU is listed in the page.In either Standard View or Advanced View, click “Power “ à “Switchable Graphics”.If the application or game is not listed, browse for it on the computer under the “ Other Applications” area and click “Browse”. Select “Browse” and check if the game or the application that you are using is listed in the page. Select “Catalyst Control Center” from the list.Follow the steps to open the “Catalyst Control Center” and to switch the graphic card.
