Color photograph of the i386 microprocessor package. Clock speeds: 16 MHz (5 to 6 MIPS) 20 MHz introduced February 16, 1987 (6 to 7 MIPS) 25 MHz introduced April 4, 1988 (8.5 MIPS) 33 MHz introduced April 10, 1989 (11.4 MIPS, 9.4 SPECint92 on Compaq/i 16K L2). Number of transistors: 275,000 (1.5 microns, now 1 micron). Bus width: 32 bits. Addressable memory: 4 gigabytes. Virtual memory: 64 terabytes. The Intel386™ microprocessor featured 275,000 transistors--more than 100 times as many as the original 4004. It was a 32-bit chip and was "multi tasking," meaning it could run multiple programs at the same time.
