Graphics Processing Unit

A graphics processing unit (GPU), also called visual processing unit (VPU), is a specialized electronic circuit designed to rapidly manipulate the memory to accelerate the creation of images in a frame buffer intended for output to a display. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles.
The term GPU was popularized by Nvidia in 1999, who marketed the GeForce 256 as "the world's first 'GPU', or Graphics Processing Unit, a single-chip processor with integrated transform, lighting, triangle setup/clipping, and rendering engines that are capable of processing a minimum of 10 million polygons per second".

Microprocessor

A microprocessor incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output. It is an example of sequential digital logic, as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system.

Microprocessors in personal computers are used for computation, text editing, multimedia display, and communication over the Internet.

Central Procesing Unit

A Central Processing Unit (CPU), is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system.

A computer can have more than one CPU; this is called multiprocessing. Some integrated circuits (IC) can contain multiple CPU on a single chip; those IC are called multicore processors.
