Intel 486 processor

The Intel 486 microprocessor was introduced in 1989 and marked a significant improvement in the processing capacity of computers over that of the previous Intel 386 (introduced in 1985). In addition, the 486 processor was the first to offer a built-in 'math co-processor'. This increased computing speeds because complex mathematical functions could be processed away from the central processor.
