The majority of GPUs on the market are actually integrated graphics. A discrete GPU is a distinct chip that is mounted on its own circuit board and is typically attached to a PCI Express slot.

An integrated GPU does not come on its own separate card at all and is instead embedded alongside the CPU. GPUs come in two basic types: integrated and discrete. This board also includes the raft of components required to both allow the GPU to function and connect to the rest of the system.

Much like a motherboard contains a CPU, a graphics card refers to an add-in board that incorporates the GPU. While the terms GPU and graphics card (or video card) are often used interchangeably, there is a subtle distinction between these terms.
