Enlarged black-and-white photograph of the Intel ® 8086 microprocessor package. Clock speed: 5 MHz (.33 MIPS) 8MHz (.66 MIPS) 10 MHz (.75 MIPS). Transistor Count: 29,000. Chip Performance: .75 MIPS (millions of instructions per second).Circuit Line Size: 3 microns. Bus Width: 16 bits. The 8086/88 microprocessors were built on 6-inch and 4-inch silicon wafers. The 8086, was Intel's new 16-bit architecture, originally designed to fill the gap while waiting for completion of the 32-bit iAPX 432 CPU, set the standard for Intel's most famous product line.
