The Intel 80486 microprocessor (alias i486 or Intel486) was a higher performance follow up on the Intel 80386. Introduced in 1989, it was the first tightly[1] pipelined x86 design as well as the first x86 chip to use more than a million transistors, due to a large on-chip cache and an integrated floating point unit. It represents a fourth generation of binary compatible CPUs since the original 8086 of 1978.
A 50 MHz 80486 executed around 40 million instructions per second on average and was able to reach 50 MIPS peak.
The i486 was without the usual 80-prefix because of a court ruling that prohibited trademarking numbers (such as 80486). Later, with the introduction of the Pentium brand, Intel began branding its chips with words rather than numbers.
