pls i bought a dell N4050 notebook which came with graphics card intel hd 3000 plus amd radeon 7450. please i want to know if both graphics card will work together or one will have to be deactivated? please shed more light and also the switchable graphics idea. thanks
They will not work together. Your laptop does switch between them. The hd 3000 will be used for anything that doesn't use much graphics power. If you play a game or anything gpu intensive then it'll switch to the 7450m. It does this automatically. If there is an issue then you can manually switch it by right clicking your desktop and go to configure switchable graphics. There should also be an option in catalyst control center.
The purpose of "switchable graphics" is to save power. When the graphic drivers detects there is a graphics intensive program running (like a game) it switches to the Radeon HD 7450. Otherwise the Intel HD 3000 will be used.. like when simply surfing the web.
