How do I test for Turbo Boost technology? AMD Turbo Core and ASUS Core Unlocker, are these technologies necessary? Is turbo core dangerous

Processors Intel Core I5 and I7, in addition to the set rated frequency, can run at a higher speed. This speed is achieved thanks to special technology Turbo Boost... When all drivers are installed, this technology is enabled and works by default. However, if you have installed all the software and you are not seeing any acceleration, it is worth monitoring Turbo Boost.

What is Turbo Boost and how does it work?

Turbo Boost is a technology specially designed for Intel processors Core I5 ​​and I7 of the first three generations. It allows you to temporarily overclock the core frequency above the specified nominal. Moreover, such overclocking is performed taking into account the current strength, voltage, device temperature and the state of the operating system itself, that is, it is safe. However, such an increase in processor speed is temporary. It depends on operating conditions, type of load, number of cores, and platform design. In addition, overclocking with Turbo Boost is only possible for the first three generations of Intel Core I5 ​​and I7 processors. Complete list devices that support this technology next:

It is also worth noting that Turbo Boost technology only works in operating rooms. Windows systems 7 and 8. Windows Vista, XP and 10 do not support this technology.

Turbo Boost is proprietary Intel technology for automatic computer... In this mode, it exceeds the nominal performance indicators, but only up to the "critical" level of the heating temperature and power consumption limits.

Features of activating turbo mode on laptop PCs

Laptops can be operated from two sources: mains power and batteries. When running on battery power, the OS “tries” to reduce power consumption to increase the operating life (by default), including by reducing (CPU). Therefore, turning on the turbo mode on a laptop has a number of features..

In older models BIOS devices had options to enable and configure this mode. Nowadays, manufacturers are trying to minimize the possibility of user interaction with the CPU, and this parameter is often missing. There are two ways to activate the technology:

• Through the operating system interface.
• Via BIOS.

How to enable Turbo Boost through the Windows interface

You can influence the state of the turbo mode by setting the desired values ​​in the parameters "Minimum processor state" and "Maximum processor state" in the current energy consumption plan:

• In the next section, follow the link "Change Extra options nutrition ".
• In the drop-down list of the "Power supply" dialog, we find the item "CPU power management".

We activate turbo mode through BIOS

This option for enabling Turbo Boost on a laptop is suitable for advanced users. It is based on resetting all settings in BIOS to default values:

• Go to BIOS.
• At the end of the menu, we find the "Load Default" section.
• We reset all settings.

To monitor the status of the turbo mode, you can use the utility Intel Turbo Boost Technology Monitor.

Good afternoon, dear audience. Today we will try to convey to you what a turbo boost in a processor is and for what purposes it is used. We're sure many of you have heard of this technology but have no idea how it works.

Turbo Boost was developed by Intel for its own chips to optimize the functionality of the chips and add performance to them without the need for overclocking.

Many people think that the technology is applicable to AMD CPUs, but they are mistaken: the red mode is called Turbo Core.

How does it work?

Speaking simple language, turbo boost mode - automatic increase in the frequency of active cores due to those that are idle at the time of operation. Unlike manual overclocking, by changing system bus in the BIOS, the monitored technology is intelligent.

The increase is determined by the task being performed and the current load on the PC. In single-threaded computing mode, the main core is overclocked to the maximum allowable values ​​by borrowing the potential of the others (others are still idle). If the entire processor is included in the work, then the frequencies are distributed evenly.

The process also affects cache memory, RAM, and disk space.

Turbo Boost also "remembers" the following system restrictions:

• peak load temperatures;
• limiting the heat dissipation of a specific motherboard;
• increasing performance without increasing voltage.

In other words, if your PC is built on a motherboard with a TDP of 95W, and the CPU operates with a current of 1.4V, while the cooling system is boxed (standard), then the turbo boost function will increase the power of the CPU in such a way as to fit into existing limitations. and do not go beyond the temperature range.

Frequency scaling principle

We figured out what the function does. Now let's describe HOW she does it. The procedure is always performed according to a single scenario: the system sees how cores (1 or more) are actively working in the processor and cannot cope with the load, i.e. need to increase the frequency. The boost increases the value of each of them strictly by 133 MHz (step) and checks the following parameters:

• voltage;
• heat pack;
• temperature.

If the indicators do not go beyond the limits, then the system throws another 133 MHz (one more step) and reconciles the indicators. When the permissible TDP is exceeded, the stone begins to reduce the frequency separately on each core by a standard step until it reaches the maximum permissible values.

Differences Between Turbo Boost 2.0 and 3.0

If version 2.0 supports a systematic increase in the operating values ​​of all processor cores, depending on the tasks being executed, then more new variant 3.0 identifies the most efficient cores to maximize their operating frequencies in single-threaded computing.

The second point is CPU support. The second version works on all chips of the Core i5 and i7 family, regardless of generation. The third is supported only by the following chips:

• Core i7 68xx / 69xx;
• Core i9 78xx / 79xx;
• Xeon E5-1600 V4 (for one socket only).

Outcomes

If you do not feel the need to overclock your processor on a regular basis, but have an Intel i5 or i7 chip, then you can safely count on intelligent overclocking in work applications and toys, if the system deems this step necessary.

At the same time, you don't have to worry about buying a motherboard with overclocking support, knowing all the subtleties of heat dissipation, as well as issues related to overclocking.

Well, if you are considering a purchase in the near future, then I recommend you this one online shop because it's proven and popular).

In the next articles we will try to highlight such a moment as in processors, and the effect of solder on the overclocking capabilities of the system. So build your dream PC.

Intel Turbo Boost- a technology that automatically increases the frequency of one or several processor cores above the nominal at maximum load, if the temperature and power consumption remain within its specifications. It allows you to increase the performance of both single-threaded and multi-threaded applications; at present, its effect is especially noticeable in applications that mainly use one or two cores (most modern games).

Intel Turbo Boost Technology supports desktop and mobile, including variants Extreme Edition, desktop and mobile, as well as server Intel Xeon for connectors. Full list on intel.com.

Turbo Boost is usually enabled in BIOS motherboards by default (and it can be disabled forcibly using the corresponding item CMOS Setup), and its activation at a specific time depends on the load, generated by applications and a headroom for temperature and power consumption.

The increase in clock frequency is carried out in portions of 133 MHz, its maximum final value depends on the model and the number of active cores at a particular time, while all active cores receive the same increase in frequency. For example, desktop Core processors i7 920/930/940/950/960 can increase the frequency of three or all four cores by 133MHz, and one or two (provided the others are inactive) by 266MHz.

Mobile processors are able to change their frequency much more strongly with the help of this technology, for example, the Core i5-540UM is capable of spending four 133MHz portions with both active cores, i.e. accelerate from 1.2GHz to 1.73GHz, and with one active core - six, i.e. right up to 2GHz.

The maximum clock speed specified in the processor specifications in TurboBoost mode is achieved, as a rule, with one or (maximum) two active cores. When the processor is overclocked by raising the reference clock frequency, the increase in performance in Turbo Boost mode is proportional to the increase in performance in the nominal mode.

Intel Turbo Boost 2.0- this technology is supported by processors based on microarchitecture Intel Sandy Bridge. The main difference from the first version is the ability to overclock not only the processor cores, but also the graphics core built into the processor.

AMD Turbo CORE- a similar technology for dynamically raising the clock frequency of active cores, at the time of writing this FAQ, it is found only in processors based on the Thuban core, fundamental differences from Turbo Boost are as follows: the maximum increase (in older models it reaches 500 MHz) at the clock frequency can be received simultaneously by up to three active cores, and inactive cores are not turned off, but transferred to a reduced power consumption mode with clock frequency 800MHz.
