The 80486, also i486 and 486, (pronounced eighty-four-eighty-six) was a family of 32-bit 4th-generation x86 microprocessors introduced by Intel in 1989 as a successor to the 80386. 486 introduced a number of enhacements to 386 including a new level 1 cache for code and data, better IPC performance, and an integrated FPU. The 486 became the first x86 chip family to exceed one million transistors.
