1 In 1965, the computer scientist Gordon Moore predicted that processor speeds would double every two years. In 1977, Atari released the 2600, the first video game console with an internal processor: a 1.2 MHz (megahertz) chip. If Moore's prediction is accurate, how fast would you expect the following consoles to be? Atari 2600 1977 Intellivision 1979 N.E.S. 1983 Atari Jaguar 1993 GameCube 2001 XBOX 360 2005 1.2 MHZ 2 a) Use Moore's Law to illustrate how fast a processor should be in the year 2027, fifty years after the first Atari. b) If consoles really do get this fast, what do you think video games will be like?
