The Intel486 bran encompasses Intel's family of i486 (incl. i487) CPUs - the second generation of 32-bit x86 microprocessors, and the first truly pipelined x86 design. Their predecessor was the Intel386, the very first 32-bit x86 processor. The first line of 486 processors was introduced in 1989 containing 1.2 million transistors (800 nanometer scale). The i486 was so named without the usual 80-prefix, because of a court ruling that prohibited trademarking numbers (like 80486). Intel dropped number-based naming altogether with the successor to the i486 – the Pentium processor.
