History

• The Q6600 was introduced by Intel on Jan. 8, 2007. The Q6700 was released several months later, on July 16, 2007. The Q6700 debuted at a price of $530, while the Q6600 was introduced at $851.
  
  

Comparison

• The Q6700 is capable of slightly faster processing speeds, with a maximum speed of 2,667 MHz, compared to the Q6600's 2,400 MHz potential. Both processors share equal, 1066 MHz bus speed capabilities. However, the Q6700 has a clock multiplier of 10, while the Q6600 has a clock multiplier of 9. The higher clock multiplier is the determining factor that allows the Q6700 to take a slight lead in processing speed. Both the Q6700 and Q6600 utilize the same socket type (Socket 775 (LGA775), as well as the same L2 cache size (8 megabytes, shared). The Q6600 has lower maximum operating temperature capabilities, with a maximum operating temperature of 60.3 degrees Celcius, compared to the Q6700's 71 degrees maximum. As their name implies, they are both quad-core processors, allowing for four cores to be utilized on a single chip.
  
  

Fun Fact

• The Core 2 Quad Q6700 and Q6600 are two of 18 different types of processors in the Intel Core 2 Quad family. The family is made up of processors that range in processing speeds of 2,133 MHz (the Q6400) to 3,000 MHz (the Q9650).
