Intel 80486

Intel 80486, also known as i486 or just 486, is the fourth-generation generation Intel x86 microprocessor.

The 80486 was capable of over 40 million instructions per second (MIPS) and offered roughly twice the performance of the 386. It featured an 8K cache for storing recent instructions. Tighter pipelining allowed for a complete simple instruction per clock cycle as compared to the two clock cycles required for a 386. An integrated floating point unit (FPU) gave faster floating point operations than 386 with a 387 math coprocessor.

Introduced in April 1989, the 80486 followed Intel’s 8086, 80286 and 80386 processors. 486 processor models, ranging in speeds from 16Mhz to 100Mhz, include: i486DX, i486SL, i486SX, i486DX2, i486DX-S, i486DX2-S, i486SX-S, i486SX2, i486DX2WB, i486GX. Intel’s main competitor AMD offered 486-compatible processors at speeds up to 133Mhz.
