What s going on with Intel Turbo Boost Technology?

Hyper-threading technology is generally about dual-purpose.

Turbo technology is generally referred to as overwork.

Detailed introduction: 1. Hyper-threading technology is to use special hardware instructions to simulate two logical cores into two physical chips, so that a single processor can use thread-level parallel computing, and then compatible with multi-level thread operation system and software, reducing the idle time of the CPU and improving the operation efficiency of the CPU.

2. Intel Turbo Boost technology is a unique feature of Intel Core i7 processors and Intel Core i5 processors. This technology intelligently speeds up processor speed calls to deliver optimal performance for heavy-duty tasks—i.e., maximizing performance to match workloads.

<>2. Next, select the "Toolbox" option in the lower right corner of the computer manager interface;

3. Next, select the "Hole Hardware Detection" function on the toolbox interface;

4. Next, select the "Hardware Overview" option above the hardware detection function interface;

5. Next, select the "CPU Information" option on the left toolbar of the Hail Tremor Bridge in the hardware overview interface;

6. Next, in the CPU information interface, you can see whether the CPU has a turbo frequency source that is accelerated sharply;

That means it's turned off and can be opened in the BIOS.

Turbo boost has no effect on the CPU, it automatically adjusts the CPU frequency according to the load of the CPU.

Here's how.

Turbo acceleration principle.

Intel has added new technology to the latest Core i series CPUs, and the main frequency of the previous CPUs is set before leaving the factory, and cannot be changed at will. The i-series CPUs all add turbo boost, so that the main frequency of the CPU can be automatically adjusted according to the needs of processing data within a certain range. It is a power management technology based on the Nehalem architecture, which analyzes the current CPU load situation, intelligently and completely shuts down some unused cores, leaving energy for the cores that are in use, and making them run at higher frequencies to further improve performance; On the contrary, when multiple cores are required, the corresponding cores are dynamically turned on and the frequency is intelligently adjusted.

In this way, the core operating frequency can be adjusted higher without affecting the TDP of the CPU. For example, the main processing frequency of an i5 is up to a maximum of , and its data processing frequency can be automatically adjusted within this range, and the capacity of this CPU is far greater than that, so you don't have to worry about the capacity of the CPU. The CPU that joins this technology can not only meet the multifaceted needs of users, but also save power, making the CPU have some smart features.

The Turbo Mode function is a technology that makes the most of the processor's productivity. It allows the kernel to run dynamic acceleration. You can turn on, off, and accelerate the operation of single or multiple cores as needed.

For example, in a four-core Nehalem processor, if a task is single-threaded, you can turn off the operation of the other three cores, and increase the running frequency of the working core, so that dynamic adjustment can improve the energy efficiency ratio of the system and the CPU as a whole.

Application of turbo acceleration.

Turbo boost technology is a trend for a new generation of CPUs, making CPUs smarter. We're multitasking a lot. , send email, and keep iPods* running in sync with mdash; We want all of these tasks to run smoothly at the same time.

Now, Intel processors built for intelligent multitasking can do more with less. Intel Hyper-Threading (HT) technology enables each core of the processor to process two applications at the same time. Turbo acceleration technology diagram.

The CPU will determine whether its current operating power, current and temperature have reached the maximum limit, if there is still room to spare, the CPU will gradually increase the frequency of the active cores to further increase the processing speed of the current task, when the program only uses some of the cores, the CPU will automatically shut down the other unused cores, and the turbo boost technology will be implemented automatically without user intervention.

It is to detect the utilization of the core by the software in real time, turn off some of the cores with low utilization, and then automatically overclock the cores used, so that the power consumption and heat generation will not exceed the maximum value of the design.

Turbo frequency refers to a technology that automatically accelerates the processor to the appropriate frequency when a running program is started, and the original running speed will be increased by 10% or 20% to ensure that the program runs smoothly.

Principle: When the processor copes with complex applications, it can automatically increase the running frequency to speed up, and easily perform multitasking with higher performance requirements. When switching work tasks, if only the memory and hard disk are doing the main work, the processor will immediately be in a power-saving state. This not only ensures the efficient use of energy, but also greatly increases the speed of the process.

By intelligently speeding up processors to maximize performance based on application needs, and up to 20% more clock speed for high-load tasks for optimal performance, i.e., maximizing performance for high-workload applications: By allocating multiple threads to AI, physics simulation, and rendering needs, users can experience a smoother, more realistic gaming experience. At the same time, Intel Intelligent Cache Technology provides a higher-performance, more efficient caching subsystem that further optimizes performance on multi-threaded applications.

It is the core CPU, i5 and i7 series, for example, a core CPU with a frequency of hertz, then when the computer processes large files or software, the maximum processing frequency of the CPU may reach about hertz. Hope it helps...

Turbo boost is designed to be energy-efficient, as it not only accelerates automatically from the base frequency, but also automatically slows down, i.e., below the base frequency. Considering the advantages and disadvantages of turbo boosting, it should be compared with a CPU with the same reference frequency but without a turbo frequency.

The actual frequency of the CPU with turbo frequency fluctuates up and down around the base frequency, and in actual use, sometimes when doing some simple operations, such as opening a text document, the actual frequency is not as good as the CPU without turbo frequency, but these simple operations are not very time-consuming, so they basically do not feel slow. When the task is more troublesome, such as opening Word, the CPU will automatically speed up until the CPU thinks that the troublesome task has been solved, and it will immediately slow down appropriately. Intel officially calls the turbo frequency intelligent acceleration, which is actually the case, and the duration of each acceleration and deceleration of the CPU is different, but it is generally a flash, and the frequency adjustment range is not fixed.

Therefore, when the power supply is sufficient (for example, the laptop battery has more power left) and the power mode is not "energy-saving mode", the turbo frequency can ensure that the actual usage speed is faster than that of ordinary CPUs, and the average power is less than that of ordinary CPUs. It's just that when the power supply ** is insufficient or the power mode is "energy saving mode", the CPU basically does not accelerate, and it remains at the lowest frequency (lower than the base frequency), then the CPU feels inferior to the ordinary CPU, but the battery life is stronger.

In fact, many times our operations are some simple and trivial operations, such as opening a folder and moving the mouse, and then the CPU does not need to be full firepower.

Therefore, if compared with CPUs with the same specifications without turbo frequency, turbo acceleration is basically no harm.

The above is all considered from the perspective of practical use and energy saving, as for the physical impact of turbo acceleration on the hardware, then I don't know.

Upstairs said so a lot,Actually, that's it.,Turn on the turbo frequency and generate a lot of heat.,The CPU will be too hot and the frequency will be reduced.,If it's a notebook, there will be a jam phenomenon when playing games in the summer.,There should be no problem if the desktop has good heat dissipation.。
