Strategy Of Intel Tick-Tock And 2nd Generation

With the launch of the second generation Core ™, Intel remains faithful to its principle of "intel tick-tock" After the "tick", which is to reduce the size of the transistors (used to make processors) from 45nm to 32nm, it is now the time of the "tock", namely the launch of a new family of processors with a new microarchitecture. In 1965, Gordon Moore, co-founder of Intel, the inventor of the Moore's Law. 

It is a rule of thumb rather than a true law of nature: Moore's Law is an empirical observation stating that the number of components on integrated circuits doubles every two years on 
Intel used this predictability to develop its strategy of intel tick-tock, which provides, in alternate years, the introduction of a new processor architecture (tock), or reducing the size of the transistor (tick) the technology of the previous manufacturing process. Whether it's a "tick" or a "tock", each step allows us to improve our processors. Take a look at the last stage, for details: The last "tick" to 32 fabrication technology nmLa size of transistors is a key element in processor technology, since a reduction in size will reduce the energy requirements and limited heat dissipation.  

The architecture of Sandy BridgeI Core ™ second generation - as happened with the family of "Westmere" - produced using a 32 nm manufacturing process that makes significant changes to the architecture. The most noticeable change is made by the graphics processor (HD Graphics 2000/3000), which not only exist on the same processor, but it is fully integrated and is part of the same day just like the processor cores.
