The term 'integrated graphics' refers to a graphics controller that shares memory with the
CPU. It is the most cost-effective alternative to a standalone 'graphics processing unit' (GPU) or a 'integrated graphics processor' (IGP), in which the GPU is built into the chipset.
A GPU incorporated into the processor is known as integrated graphics. Integrated graphics hardware does not have a separate graphics/video memory bank. Instead, the GPU makes use of shared system memory with the CPU.
A GPU that is distinct from the processor is known as discrete graphics. Discrete graphics has its own dedicated memory separate from the CPU.
