When referencing an Intel 386 CPU, the DX or 386DX is the full 386 with a 32-bit data path, in contrast to the 386SX, which uses a 16-bit data path. In an Intel 486 CPU, the DX or 486DX designation has a different meaning. It refers to the full 486, which contains the math coprocessor, in contrast to the 486SX, which does not.
