8. Graphics cards (chips) can contain 100's of specialized, "mini-cpu's"

On the standard motherboard if you will, is a chip that may contain anywhere from 1 to 8 individual CPU's that can run in parallel.

As graphics became for sophsticated, the invention of the GPU (graphics processing unit) came along, very small, specialized and limited processors that could just handle the math & operations required to paint pixels on screens. Graphics chip manufacturors were able to put many, many GPU's on a single chip, so the "painting" of the image on a screen would happen with processors running in parallel, and the time to create a single screen got extremely fast.

Software programmers can utilized these graphics cards to not just create pixels to create images, but process any data they want.

My graphics chip has 768 individual processing units, and it is just a mid-range chip.
