Enable Turbo mode regulator chip power consumption for enterprise energy saving

Does your IT system cost more and more? Are you at pains to reduce power and conserve energy? We will from the chip, components, systems, software and even data centers, and many other levels, from a number of points of view, sorted out a series of practical it energy-saving coup, I believe there is always a trick for you!

In the next generation of Nehalem architecture 45 nm, which will be launched in the four quarter of 2008, Intel will introduce a turbo mode technology that, when power conditions permit, heavy application software can automatically follow predefined steps to increase the processor's frequency to meet current processing needs.

Turbo mode can take full advantage of the processor's energy footprint. Because, in multi-core processors, not all cores are in a load-activated state, and not all activated cores run in full power, so all the extra power space is converted to the higher frequencies of other active cores.

For example, suppose a quad-core processor is designed to consume 80 watts, when two of these cores are activated and the other two are idle, it is possible to use only 40 watts, or 40 watts of residual power, so that turbo mode allows the machine to automatically lift the frequency of the two activated cores to a level of 80 watts. So that the job can be completed in the shortest amount of time, and then the CPU will return to the idle state with less power consumption.

The timing of the system in Turbo mode depends on the load, and Turbo mode can be activated or turned off in the BIOS and then invoked in the operating system.
