What is the cpu dynamic acceleration frequency?

Whether it is Intel or AMD, it is called Turbo Boost or Pricision Boost, which actually means the same thing, dynamic acceleration frequency. This acceleration frequency mainly affects the performance of a single core.

First of all, acceleration frequency can improve single-core/dual-core computing capabilities, especially for software that cannot fully utilize multiple cores, and must rely on high frequency to improve computing efficiency. Secondly, where hyper-threading does not work, the most primitive and violent method must be used to achieve the goal, and the acceleration frequency emerged as the times require. So it can be seen that entry-level processors can have no hyper-threading and a small number of cores, but they will not have no acceleration frequency.

Actually, the acceleration frequency is more like an "overclocking" action that does not require manual intervention. Users do not need to enter the BIOS to adjust the voltage, frequency, multiplier, etc., and the calculation When the demand comes,

　　CPU

will automatically determine whether the frequency needs to be accelerated, and dynamically adjust it within the allowable range of the thermal power consumption design, and even turn off the idle frequency under certain circumstances. core!

Hyper-threading is not the acceleration frequency

Many friends easily confuse acceleration frequency and hyper-threading. In fact, they are two different technologies. Hyper-Threading (HT) first appeared on the Pentium 4 in 2002. It uses special hardware instructions to simulate two logical cores into two physical chips, allowing a single processor to use threads. Level parallel computing, and thus compatible with multi-threaded operating system

and software, reduces the idle time of the CPU and improves the operating efficiency of the CPU. However, this technology does not appear on any processor like acceleration frequency. It is not available in many models of entry-level products such as the Pentium series.

The biggest advantage of the acceleration frequency is that many entry-level and mid-range processors have good game performance - because many games only use two cores at most. The computing performance can even compete with high-end processors. Of course, this is not an absolute factor, including the dependence of the game itself on the processor, which will also affect game performance.
