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 heating temperature limits and power consumption.
Features of activating turbo mode on laptop PCs
Laptops can operate from two sources: mains power and batteries. When powered by a battery, the OS, to increase operating life (by default), “tries” to reduce energy consumption, including by reducing (CPU). Therefore, turning on turbo mode on a laptop has a number of features.
In older models Device BIOS had options to enable and configure this mode. Nowadays, manufacturers are trying to minimize the possibility of user intervention in the operation of the CPU, and often this parameter is 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 turbo mode state by setting the required values in the “Minimum processor state” and “Maximum processor state” parameters in the current power consumption plan:
- In the next section, click on the “Change advanced power settings” link.
- In the drop-down list of the “Power Options” dialog we find the “CPU Power Management” item.
Activate turbo mode via BIOS
This option to enable Turbo Boost on a laptop is suitable for advanced users. It is based on resetting all settings in the BIOS to default values:
- Let's go to the BIOS.
- At the end of the menu we find the “Load Default” section.
- Reset all settings.
To monitor the turbo mode status, you can use the utility Intel Turbo Boost Technology Monitor.
Simply put, Turbo Boost is the ability to increase the frequency of one or more actively used processor cores at the expense of the rest, which are this moment are not used. Unlike banal overclocking (for example, by changing the frequency multiplier in the BIOS), Turbo Boost is an intelligent technology.
Firstly, the increase in frequency occurs depending on the current load of the computer and the nature of the tasks being performed. For example, for fast work For single-threaded applications, it is important to speed up one core as much as possible (others are still idle). For multi-threaded tasks, you will need to “boost” several cores.
Secondly, unlike the same overclocking, Turbo Boost remembers the limitations of power, temperature and current as part of the design power (TDP, thermal design power). In other words, overclocking using Turbo Boost does not go beyond the normal operating conditions of the processor (all these indicators are constantly measured and analyzed), does not threaten overheating and, therefore, does not require additional cooling.
System operating time in Turbo mode Boost depends on workload, operating conditions, and platform design.
Overclocking subtleties
Let’s immediately make a reservation that frequency changes using Turbo Boost technology occur discretely. The minimum unit for increasing or decreasing the frequency of one or more active cores is a step, the value of which is 133.33 MHz. Please note that the frequency for all active cores changes simultaneously and always by the same number of steps.
Let's look at how Turbo Boost technology works using the following example.
IN currently In a quad-core processor, two cores are active and their frequency must be increased. The system increases the frequency of each of them by one step (+133.33 MHz) and checks the current, power consumption and temperature of the processor. If the indicators are within the TDP, the system tries to increase the frequency of each of the active cores one more step until it reaches the set limit.
If increasing the frequency of each of the two active cores by one more step (+133.33 MHz) leads the system to exceed the standard thermal package (TDP), the system automatically lowers the frequency of each core by one step (-133.33 MHz) to return normal condition. As mentioned above, you cannot change the frequency of active cores individually. That is, in principle, it is not possible for the frequency of one active core to change by one step, and the frequency of another - by two steps.
Turbo Boost technology is supported on desktop and mobile processors Intel Core i5/i7, but different models may have different modes of operation. For example, for Intel processors Core i5 600 series and Core i7 900 series for mobile and desktop processors, as well as Core i7 Extreme Edition The following operating modes exist.
Few owners of computers with i5 and i7 processors know that these “hearts” can briefly operate above their factory frequency, that is, faster.
This is achieved through special technology from Intel, which, if installed all correct drivers enabled and running by default. Let's check it out and look at this work - it will help us with this Turbo Boost technology monitor.

Briefly about Turbo Boost technology
As you understand from the above, this technology allows you to overclock the processor frequency above the nominal value set at the factory for a short time. This happens absolutely safely, because voltage, current, temperature and even the state of the operating system are taken into account.
The duration of this acceleration depends on the operating conditions, type of workload, number of active cores, and platform design. Computer performance can increase very noticeably and significantly.
All this is wonderful, of course, but there is a small fly in the ointment - this technology does not support all processors, but only the first three generations of i5 and i7...

Checking the operation of Turbo Boost
The Turbo Boost technology monitor for older i5 and i7 processors has already been removed from official resources Intel Corporation, but the installer continues to “walk” on the Internet - I’ll give a link to it at the end of the article.
Let's check how Turbo Boost works or find out whether this technology is actually used on our computer?
Installing the monitor is quick and easy. We launch it and get such a widget on the computer screen. We poke at it right click mouse and select the size...
...you can also attach it here on top of all windows so that you can observe the operation of the technology, for example, when launching any computer programs.
The frequency of my processor set from the factory is 2.3 GHz. Just by moving the mouse and opening and closing several windows, I “caught” the moment of processor acceleration with my screenshot...
After making sure that everything was working as it should, I removed the Turbo Boost technology monitor, which I advise you to do as well.

Good afternoon, dear audience. Today we will try to explain to you what turbo boost is in a processor and for what purposes it is used. We are sure that many of you have heard about this technology, but have no idea how it works.
Turbo Boost was developed by Intel for your own chips, in order to optimize the functionality of the chips and add performance to them without the need for overclocking.
Many people think that the technology is also applicable to CPUs made by AMD, but they are mistaken: the red ones have a mode called Turbo Core.
How does it work?
Speaking in simple language, turbo boost mode – automatically increases the frequency of active cores due to those that are idle at the time of operation. Unlike manual overclocking by changing the system bus in the BIOS, the technology under review is intelligent in nature.
The increase is determined by the task being performed and the current PC load. In single-threaded computing mode, the main core is accelerated to the maximum permissible values by borrowing the potential of the others (others are still idle). If the entire processor is turned on, the frequencies are distributed evenly.
The process also affects cache memory, RAM, and disk space.
Turbo Boost mode also “remembers” the following system limitations:
- temperatures at peak load;
- limiting the heat generation of a specific motherboard;
- increasing productivity 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 value 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 restrictions and not go beyond the temperature limits.
The principle of increasing frequencies
We figured out what the function does. Now let's describe HOW she does this. The procedure is always performed according to the same scenario: the system sees how the processor cores (1 or more) are actively working and cannot cope with the load, i.e. need to increase frequency. The boost increases the value of each of them strictly by 133 MHz (step) and checks the following parameters:
- voltage;
- heat package;
- temperature.
If the indicators do not go beyond the limits, then the system adds another 133 MHz (another step) and re-checks 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 performed, then the newer version 3.0 determines the most efficient cores in order to maximize their operating frequencies in single-threaded calculations.
The second point is CPU support. The second version works on all Core i5 and i7 family chips, 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).
Results
If you don't 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 games if the system deems this step necessary.
At the same time, you don’t have to worry about buying a motherboard with overclocking support, or know all the intricacies of heat dissipation, as well as issues related to overclocking.
Well, if you are considering a purchase in the near future, then I recommend this one to you online store, because it is proven and popular).
In the following articles we will try to cover this point in processors and the influence of solder on the system overclocking capabilities. So, create your dream PC.
Hello.
Not long ago I “dealt” with the slow operation of one laptop (I note that the model was equipped with a modern Intel Core i7-7700HQ, i.e. quite a powerful thing) . As it turned out later, the reason why it slowed down in games was disabled Turbo Boost technology (is on modern processors, allows you to increase processor performance during load), and not updated drivers for the video card (those that were “installed” during the installation of Windows were used).
I think that many users of their devices face a similar problem (low performance). Actually, this article is just about what parameters can affect the performance of a laptop, how to check and change them...
The material is relevant for modern laptops with Intel Core i3, i5, i7 CPUs.
Power settings
The first thing I recommend doing is paying attention to the power supply. The fact is that the default settings on most laptops are set for "optimal" operation of the device (i.e., often aimed at saving energy so that the device can work longer from battery). At the same time, if the processor power supply is set to low, the function will be automatically disabled (which will seriously affect performance).
First, pay attention to the system tray: there should be a “battery” icon there. By clicking on it with the left mouse button, you can see a window in which there is a “performance” slider, move it to maximum.
To find out if Turbo Boost technology is being used your laptop, you need to install one of the special. utilities:
- There is a special on the official website. monitor to monitor processor performance (see screenshot below, left). If your CPU performance "jumps" above the dark blue mark (in the example below 2.5 GHz) - then Turbo Boost is supported. To test, start some game/watch a movie, etc.
- - in the main program window (CPU tab) pay attention to the parameter Core Speed(the frequency there will constantly change, but its maximum should reach the value that we saw in the CPU specification, in the Max Turbo Frequency column, i.e. 3.1 GHz or 3100 MHz, which is the same thing (see screenshot below and higher)).
Does Turbo Boost work on a laptop (clickable). Monitor from the Intel website and the utility (on the right) CPU-Z
Why Turbo Boost may not work(*if supported by your CPU):
- due to power settings (be sure to set the CPU power to 100%, see the first step in the article);
- missing drivers();
- the technology can be disabled in the BIOS/UEFI (see screenshot below, Turbo Mode).

High temperature, overheating
Another fairly popular reason for decreased performance in laptops is overheating. The fact is that when the processor temperature reaches a certain point, it begins to reduce its performance (to lower the temperature). If the temperature continues to rise and reaches a critical point, the device turns off. Modern two-level protection (you may have already heard this term somewhere).
By the way, the critical processor temperature, upon reaching which the laptop will turn off, is indicated in the specification on the Intel website (see the “T junction” column).
In general, in general, it is highly undesirable for the processor temperature to exceed 70 C.
It is not uncommon for performance to deteriorate due to the fact that in addition to the game that the user launched (say), some third-party “heavy” applications are running on the laptop. It is not uncommon for users to catch mining viruses (which have become popular recently).
First, I recommend opening Task Manager (combination Ctrl+Shift+Esc) and sort applications by CPU load. It’s not uncommon for “unclear” processes to load the system (I'm not even talking about the fact that sometimes the CPU is loaded, but the dispatcher may not show what...).

Not optimal video driver and game graphics settings
Because Many people are most often dissatisfied with performance in games - this topic has been included in a separate subsection of the article.
Most users do not believe that just by setting the settings of the video driver and the game itself, you can significantly increase the number of . I note that sometimes FPS increases by 100% or more!
The first thing I recommend is optimizing your video driver settings. Those. set the highest performance and disable some “effects” (this can be done by going to the video driver settings and activating the advanced user mode).
I already have 3 articles on my blog on setting up video cards from Intel, AMD, nVidia. To avoid repetition here, here are the links:
- AMD - https://site/kak-uskorit-videokartu-amd-radeon.html
- nVidia-
- Intel HD -
In addition, pay attention to the graphics settings in the game itself. Particular attention to:
- resolution (the higher it is, the greater the load on the video card; when it decreases, the number of FPS increases);
- graphics quality;
- detailing;
- effects and shadows (if any).

Not an optimized system
And I can’t help but note in this article that you can slightly increase the performance of a laptop by Windows optimization. As a rule, it includes several stages:
- Disabling services: some of them are simply not needed by many, and they take up resources;
- Registry cleaning, removal junk files(over time, many people accumulate tens of gigabytes of junk files that affect performance);
- Disk Defragmenter(relevant for HDD, SSD does not need to be defragmented);
- Setting up Windows startup(it’s no secret that as new programs are installed, the system’s startup “expands”; moreover, you can use many startup software very rarely, and it will take up time every time you turn on the PC. Is it necessary?!);
- Updating old drivers;
- Enabling performance// in Windows settings
- Disabling indexing files on disk.
How to do all this (step by step and without the risks of “ruining” something) is described in this article:
That's all for now...
All the best!
