GCN at 25: March of the microprocessors

There is a lot more to a computer processor than clock speed, especially today. But as a quick point of reference for Moore's Law, here's a look at the first 35 years of Intel microprocessors.

1970Intel introduces the first microprocessor, the 108 KHz Intel 4004.

1974The Intel 8080 ups the ante to 2 MHz.

1979The 8088 uses a 16-bit architecture in 4.77 MHz and 8 MHz versions.

1982The Intel 282, also known as the P2, is available in 2 MHz, 10 MHz and 12 MHz versions.

1985The 386, aka the P3, makes a considerable leap forward with a 32-bit architecture and clock speeds ranging from 16 MHz to 33 MHz.

1989The 486, or P4, is released with clock speeds of 25 MHz, 33 MHz and
50 MHz, with a built-in memory cache and architecture that triples the speed of the 386.

1993After a few specialized versions of the 486, Intel delivers the Pentium, with a speed from 66 MHz and expanded address and data buses. Two generations later, the Pentium would reach 200 MHz.

1997The Pentium II arrives, at 233 MHz and with an easily removable casing.

1999The Pentium III arrives with 500 MHz.

2001The first Pentium 4 is released at 1.3 GHz.

2004The latest Pentium 4, nicknamed Prescott, is released at 4 GHz.
