CPUs Used in Personal Computers

Since 1978, Intel's processors have evolved from the 8086 and the 8088 to the 80286, 80386, and 80486, to the Pentium family of processors. All are part of the 80x86 line. Intel's Pentium family of processors includes the Pentium, Pentium Pro, Pentium with MMX, Pentium II, Pentium III, Celeron, and Xeon processors. The earliest Intel processors included only a few thousand transistors. Today's Pentium processors include 9.5 million transistors or more.
