what is the difference between dedicated graphics and integrated graphics
Where-as Integrated Graphics refers to having a Graphics Processor that is integrated into the motherboard, Dedicated Graphics refer to separate add-in cards that contain the Graphics Chip and all of the support electronic components for the Graphics chip.
System Performance : Where integrated graphics borrow from the main system memory to provide the frame buffer, what actually holds the content of what is displayed, Dedicated Graphics have their own frame buffer. This results in the graphics card being able to make better use of it's resources.
