uses a 16-bit data bus instead of a 32-bit data bus. It has a 24-bit address bus. It is faster than the 286, and more importantly, like the full-size 386, provides more flexibility in running existing DOS applications. Intel's version runs at 16 MHz, while AMD's can run at up to 33 MHz. It comes in a PFP package.
