Timeline Part 1

• April 1972- Intel 8008 it’s clock speed was 200 kilohertz and had 3,500 transistors.

• December 1974- A remake of Intel 8008 with a clock speed of 2 MHz and 6,000 transistors.

• August 1976- The Intel 8085- Had a clock speed of 5 MHz and 6,500 transistors.

• September 1978- Intel 8086- It’s clock speed was at 10MHz was an5 MHz increase by from the last one and rose to 29,000 transistors.

Timeline Part 2

• In February 1982, the Intel 286 reached a clock speed of 12 MHz and jumped to 134,000 transistors.

• The Intel 386 was 16 MHz and had 275,000 transistors.

• In June 1996 the Pentium 1 came out with 300 MHz clock speed and 3.3 million transistors.

Timeline Part 3

• In November 2006 the Core 2 Extreme QX6700 came out with 8 MB and 582 million transistors.
