Because of what the low performance of the Intel processor on the laptop. How can you speed it up? (about Turbo Boost)

Hello.

Not so long ago I "dealt" with the slow operation of one laptop (note that the model was equipped with a modern Intel Core i7-7700HQ, i.e. quite a productive piece ) ... As it turned out later, the reasons why it slowed down in games was the disabled Turbo Boost technology (available on modern processors, it allows you to raise the processor's performance during load), and not updated drivers for the video card (those that were "supplied" 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.

Reasons for the decline in processor performance. How to speed up a laptop

Power settings

The first thing I recommend to do is pay attention to the power supply. The fact is that the default settings on most laptops are set for "optimal" device performance (that is, often aimed at saving energy, so that the device can work longer on battery power). In this case, if the reduced power supply of the processor is set, the function will be automatically disabled. Turbo Boost (which will seriously affect performance).

First, pay attention to the system tray: there should be a "battery" icon. By clicking on it with the left mouse button, you can see a window in which there is a "performance" slider, move it to the maximum.

Diet

Next, you need to open the control panel, section "Hardware and sound / Power supply". After that, you must either select a power supply scheme with high performance, or open the settings of the current scheme (as in the screenshot below).

Then follow the link "Change advanced power settings".

Extra options

Next, find and open the "Processor Power Management" tab: set the minimum and maximum processor state to 100% (both from the battery and from the network, an example in the screenshot below).

In addition, pay attention to the various power managers that come with your laptop drivers. For example, Lenovo, Sony and other manufacturers have similar things.

Turbo Boost does not "work"

Turbo Boost is an Intel technology that automatically increases the clock speed of the processor under heavy load. Which in turn lead to increased productivity. If we "discard" some terminology, it resembles a "smart self-overclocking" of the CPU.

So, the bottom line is that Turbo Boost technology can be supported by your processor, but it may not be enabled (not used)!

This technology is supported by Intel Core i5, i7 (and 8th generation i3) processors. To check if your CPU supports this technology, you need to go to the website //ark.intel.com/#@Processors and find your processor model. If it does, you will see the line "Max Turbo Frequency" in the specifications (see the screenshot below).

Turbo Boost

To find out if your laptop is using Turbo Boost technology, you need to install one of the special. utilities:

  1. on the official site of Intel there is a special. monitor, to monitor the performance of the processor (see screenshot below, left). If your CPU performance jumps above the dark blue mark (below 2.5 GHz in the example), then Turbo Boost is supported. For testing - run some game / watch a movie, etc.
  2. CPU-Z - 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 (see the screen below and above)).

Why Turbo Boost may not work (* if supported by your CPU):

  1. due to power settings (be sure to set the CPU power to 100%, see the first step in the article);
  2. lack of drivers (utilities for auto-update);
  3. the technology can be disabled in BIOS / UEFI (see screenshot below, Turbo Mode). How to enter BIOS

High temperature, overheating

Another popular reason for laptop performance degradation is overheating. The fact is that when the temperature of the processor reaches a certain point, it starts to decrease its performance (in order 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 temperature of the processor, upon reaching which the laptop turns off, is indicated in the specification on the Intel website (see the "T junction" column).

T junction (temperature, upon reaching which, the PC will turn off)

In general, in general, it is highly undesirable for the processor temperature to exceed 70 C.

How to find out the current temperature, what is considered normal, and how to deal with overheating, you can learn from this article: //ocomp.info/greetsya-noutbuk.html

Loading by extraneous applications

Often, when performance decreases due to the fact that in addition to the game that the user has launched (say), some third-party "heavy" applications are running on the laptop. It is not uncommon for users to catch miner viruses (which have become popular recently).

First, I recommend opening Task Manager (shortcut Ctrl + Shift + Esc) and sort applications by and load on the PC. Often, when "incomprehensible" processes load the system (I'm not talking about the fact that sometimes the CPU is loaded, and what - the dispatcher may not show ...).

Task Manager

To help!

I recommend that you read the article on how much the CPU can be loaded for no apparent reason: //ocomp.info/protsessor-zagruzhen-na-100-i-tormozit.html

Also, it will not be superfluous to check the PC completely for viruses and malware (note that one classic antivirus is not enough for this procedure). For how to do this, see this article: //ocomp.info/esli-antivirus-ne-vidit-virusov.html

Not optimal video driver and game graphics settings

Because many are most often dissatisfied with the performance in games - a separate subsection of the article has taken this topic out.

Most users do not believe that just by setting the video driver settings and the game itself, you can significantly increase the number of FPS. Note that sometimes FPS increases by 100% or more!

The first thing I recommend is to optimize your video driver settings. Those. set the highest performance and disable some "effects" (you can do this if you go to the video driver settings and activate the advanced user mode).

Intel graphics settings

I already have 3 articles on my blog on setting up video cards from Intel, AMD, nVidia. In order not to repeat myself, here are the links:

  1. AMD - //ocomp.info/kak-uskorit-videokartu-amd-radeon.html
  2. nVidia - //ocomp.info/kak-povyisit-proizvoditelnost-videokart-nvidia.html
  3. IntelHD - //ocomp.info/kak-uskorit-videokartu-intelhd-povyishenie-proizvoditelnosti-minimum-na-10-15.html

In addition, pay attention to the graphics settings in the game itself. Particular attention to:

  1. resolution (the higher it is, the greater the load on the video card, when it decreases, the number of FPS increases);
  2. quality of graphics;
  3. detailing;
  4. effects and shadows (if any).

Not optimized system

And I still can not help but note in this article that you can slightly increase the performance of a laptop by optimizing Windows. As a rule, it includes several stages:

  1. Disabling services: some of them are simply not needed by many, and they take resources away;
  2. Cleaning the registry, deleting junk files (over time, many accumulate tens of gigabytes of junk files that affect performance);
  3. Disk defragmentation (relevant for HDD, SSD does not need to be defragmented);
  4. Configuring Windows startup (it's no secret that as new programs are installed, the system startup "expands", and you can rarely use many startup software, and it will take time every time you turn on the PC. Is it necessary ?!);
  5. Updating old drivers;
  6. Turn on performance // in Windows settings
  7. Disable indexing of files on the disk.

How to do it all (step by step and without risks, "spoil" something, is described in this article: //ocomp.info/super-optimizatsiya-windows-10.html

So far, in fact, that's all ...

All the best!
