What is CPU core frequency acceleration

Intel Core-frequency Acceleration technology is a unique feature of Intel's high-end processors and a new Intel technology. This technique can be understood as automatic overclocking. When the core-frequency acceleration, the CPU will automatically adjust the CPU frequency according to the current task amount, thus heavy task to play the greatest performance, light task to maximize energy-saving advantages. Core-frequency acceleration is intel in the latest Nehalem architecture of the processor to achieve a automatic increase in CPU clock frequency of a "regular overclocking" technology, English named "Intel Turbo Boost Technology", referred to as "Turbo boost."

Turbo Boost, as the name implies, is the acceleration technology, it is based on the Nehalem architecture of power management technology, by analyzing the current CPU load situation, intelligently completely shut down some of the core, the use of energy to the core, and make them run at a higher frequency, further improve performance; When multiple cores are needed, the corresponding core is dynamically opened and the frequency is adjusted intelligently. In this way, without affecting the CPU of TDP (thermal power design), the core operating frequency can be higher.

　　The difference between the core frequency acceleration technology and the processor overclocking essence

Rui-frequency acceleration technology without user intervention, automatic implementation, overclocking requires the user to manually adjust the various indicators of the processor-times frequency, FSB, CPU voltage, replacement power and cooling scheme.

The core-frequency acceleration technology allows the processor to run in the technical specifications, safe and reliable, without any additional investment, the system runs stably; overclocking can lead to more processor power consumption than technical specifications, resulting in excessive power and processor thermal solutions that increase the cost of the system. And overclocking can cause the system to run unstable.

Core-frequency acceleration technology to enjoy the full Intel Processor Product Warranty terms, overclocking is not covered by the processor warranty, the business exemption-because overclocking damaged the processor can not enjoy the warranty regulations.

　The working way of the Rui-frequency acceleration

By analyzing the current load on the CPU, intelligently completely shuts down some of the unused cores, leaving the power to the core being used, and enabling them to run at higher frequencies to further improve performance; On the other hand, when multiple cores are needed, dynamically open the corresponding core and intelligently adjust the frequency. In this way, without affecting the CPU of TDP (thermal power design), the core operating frequency can be higher.
