Intel 386

Intel's "386" processor, also known as i386, is the first fully 32-bit chip using the x86 architecture. This would allow it to address much more memory than previous generations of chips, and its variant, the 386-SX would serve to provide cheaper models to the general public.

The original 386 processor would be renamed to the 386-DX to set it apart from the budget SX model, of which utilized only external 16-bit data and 24-bit address buses.
