Modern computer [[graphics card]] displays almost overwhelmingly use raster techniques, dividing the screen into a rectangular grid of [[pixel]]s, due to the relatively low cost of raster-based video hardware as compared with vector graphic hardware. Most graphic hardware has internal support for [[BitBLT|blitting]] operations or [[Sprite (computer graphics)|sprite]] drawing. A [[co-processor]] dedicated to [[BitBLT|blitting]] is known as a ''[[Blitter]] chip''.

Classic 2D [[graphics chip]]s and [[graphics processing unit]]s of the late 1970s to 1980s, used in [[8-bit computing|8-bit]] to early [[16-bit computing|16-bit]], [[arcade game]]s, [[video game console]]s, and [[home computer]]s, include:
