What is 80486 (i486) in Computer Processor?

In 1989, Intel introduced the 80486, also referred to as the i486 or 486, as a microprocessor. It was the fourth generation of the x86 architecture and had many more features and better performance than the 80386 before it.

The on-chip cache, a compact, quick memory that stored frequently used data and instructions, was one of the 80486’s major advancements. This significantly improved the processor’s performance by enabling faster data access.

The 80486 also introduced pipelining, which increased speed by allowing arithmetic and logical operations to be carried out simultaneously. Additionally, compared to earlier x86 processors, it had a larger instruction set, enabling it to carry out more difficult tasks.

The 80486 was a 32-bit processor, which was a significant improvement over the 16-bit processors of the time because it could process data in 32-bit chunks. It came in single- and dual-core versions and had a clock speed of up to 50 MHz.

In the 1990s, the 80486 was a popular processor for servers and personal computers. In 1993, the Pentium processor took its place. Although it no longer meets modern standards, it still marks a significant turning point in the development of x86 processors.
