The 68000 family architecture leads in high-resolution graphic displays that respond very rapidly to user actions. To enable this performance, a microprocessor must have as many large, general-purpose registers as possible. The 68000 microprocessor has 16 general-purpose registers, each of which is 32-bits wide.

MS-DOS, computers have only recently (with the 80386) been equipped with any 32-bit registers. The 80386 has only 8 general-purpose registers. This is one reason why it is difficult to generate high-quality graphics on Intel-based computers, especially without the aid of a coprocessor.
