Since the arrival of its Core processors Intel decided to put the accent on energy consumption by avoiding as much as possible wastage. With the arrival of Nehalem the foundry set up a technology called " Power Gating". It makes it possible on these processors to cut one or more cores when they are not in use, their consumption being then close to 0W. The gain in energy is then very substantial since the transistors are not on stand-by but turned off. Currently this is only possible; on the scale of a complete core. In the summary at an Intel conference, PCinpact outlined the future intentions of the foundry. This idea is to push even further Power Gating and thus it will make it possible to shut off the current to a part of a core when this part it is not exploited. This possibility will initially be installation in chips intended for the small apparatuses
