Computer Basics – What’s Inside a Computer? GPU

GPU = Graphics Processing Unit. Inside a computer, minding its own little business, we find the GPU. A microprocessor like the CPU, it is different in that it specializes in processing data related to the rendering of graphics (video) in a computer. It can be embedded in the motherboard, or in a dedicated graphics card plugged into one of the buses as an extension card. Generally speaking, a GPU in a dedicated graphics card has more power than one embedded in the motherboard.

Even though it seems that the term dedicated is synonym with a GPU being in an extension card instead of embedded in the motherboard, the factor that actually defines it as dedicated is whether or not it uses the general random access memory (sharing it with the CPU), or if it has its own dedicated memory. That also defines its power.

At the moment of this writing, over 90% of personal computers use integrated graphics solutions, since it is more cost effective and only a small portion of the users demand more than what integrated graphics can offer. Chief amongst those included in the remaining 10% are avid computer games users (gamers), and those who runĀ  graphically intensive programs such as computer-aided design (CAD) programs.

So there you have it, another piece in the computer puzzle, the GPU.
