Kind of like a computer in a sense. Every part needs instructions on how to properly perform their duty correctly. Now with the recent phones that HTC has put all have the same insides as such but a different case on the outside. As we speak, there is a graphics chip that is supposed to handle all the 2D and 3D effects on the phone, handle what is displayed on the screen and video playback. At the moment, the phone is not setup that way because all the work is being put on the main processor instead of offloading all the visual duties to the graphics card because of the lack of drivers for Windows Mobile.
