There are two type of notebook graphics Card:

- the Integrated Notebook Graphics Processing Units

- the Dedicated Notebook Graphics Processing Units.

Integrated Notebook Graphics Processing Units :

Integrated Notebook Graphics Processing Units are suffering from the necessity to share memory with the main system, and this result in slower performance all around, second problem is that most integrated GPU lack true support for actual 3D extensions such as Pixel Shader 2, Vertex Shader, and Hardware Transform and Lighting.The positive is that integrated GPU are producing no heat of their own and they are almost using very little power, and this allows to more comfortable use and longer battery life.

Basically, it is well know that integrated cards stand no chance against real graphics chips, but for example Mobility Radeon x1100 (the new x200M) IGP is one of the only integrated chip that can deliver acceptable frame rates with full DirectX 9 support.

Dedicated Notebook Graphics Processing Units :

Only two companies are currently manufacturing dedicated graphics chips : ATi and nVidia.

These card feature more hardware support for advanced DirectX 9 and OpenGL 1.5 functions. Most importantly, they get that name of dedicated graphics cards from the fact that they use exclusively dedicated Video Ram, ensuring smooth and snappy performance. The problem is that dedicated video cards use much more power than integrated chips, resulting in more heat and shorter battery life.
