How do I perform a Turbo Boost Technology Check? Because of what the low performance of the Intel processor on the laptop. How can it be accelerated? (about Turbo Boost) How to turn on the turbo processor on a laptop

Intel Core I5 ​​and I7 processors, in addition to the set nominal frequency, can work 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 acceleration is not observed, it is worth monitoring Turbo Boost.

What is Turbo Boost and how does it work?

Turbo Boost is a technology that was developed specifically for the first three generations of Intel Core I5 ​​and I7 processors. It allows you to temporarily overclock the frequency of the cores above the set nominal value. At the same time, such overclocking is performed taking into account the current strength, voltage, temperature of the device and the state of the device itself. operating system, which is safe. However, this increase in processor speed is temporary. It depends on the operating conditions, type of load, number of cores and platform design. In addition, overclocking using Turbo Boost is only possible for Intel Core I5 ​​and I7 processors of the first three generations. The full list of devices that support this technology is as follows:

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.

As practice shows, every user at least once faced the problem of low performance ("slowdown" of work) of the device. In this article, we will talk about Turbo Boost technology - what it is, what it is for. We are sure that many have heard about it, but they are unlikely to be able to accurately answer these questions.

Purpose

Turbo Boost technology (from the English. "The occurrence of a whirlwind") increases the performance of the laptop by automatically increasing the clock frequency of the processor (working cores) at the time of high load. At the same time, the nominal indicators of power, temperature and current do not exceed the "critical level". Created by Intel for Core I5, I7 processors.

Important. If you have a modern device, an Intel Core i5, i7 central processor, then the "smart overclocking" technology is most likely supported by the processor, but not activated. After installing the drivers and making settings, the mode works by default.

Features of activating a turbo boost on a laptop

The mobility of the laptop is ensured by the possibility of power supply from the rechargeable battery. At the same time, the system compensates for the time of continued autonomous use of the device by reducing its own resource consumption. One of them is the decrease in the clock speed of the processor.

In previous versions of the BIOS, the user was given the opportunity to run this mode and make settings on their own. In modern devices, the manufacturer tries to limit any interference with the processor as much as possible, so this is not provided. The mode is activated like this:

Turn on Turbo Boost through the Windows interface

Here is the algorithm:

1. Open "Control Panel" - "Power Options". Select (check the box) next to the High performance power plan. If there is no such parameter in the first window, then open the scheme settings (see figure)
2. Next section. Follow the link to "Change advanced power settings"
3. The "Power Options" window opens, look for "Processor Power Management".
4. To enable Turbo mode, you must: put 100% in front of the Minimum and maximum state of the processor from the battery and the network. If this indicator decreases, the mode will automatically turn off the OS.

Important. Many manufacturers (Lenovo, Sony, etc.) supply their own power managers as part of the driver kit for the device.

Activate turbo mode via BIOS

This method of enabling the mode on the device is recommended for advanced users who do not need to describe in detail how to enter the BIOS. Its main purpose is to reset all settings to factory settings.

1. We enter the BIOS.
2. At the bottom we are looking for the “Load Default” subsection.
3. Reset all settings to default values.

Checking the operation of the mode

Intel has developed the Turbo Boost Technology Monitor program to check the operation of the mode. It can be downloaded for free from the manufacturer's website. It is not "heavy" only WW23. Installation and operation will not be difficult even for an untrained user. Procedure:

• Click with the mouse on exe file on a laptop, follow the instructions of the installation wizard.
• After complete installation the program dialog box opens. The nominal frequency of the processor is indicated at the bottom of the window.
• You can see the Turbo Boost mode at work if you turn on video broadcasts or start the game.
• If the mode is not enabled, then follow the instructions described above.

Introduction

I remember a computer that I bought back in 1998. It used a Pentium II 233 processor on an Intel Deschutes core with a motherboard Asus board P2B. The system was fast, but I wanted to do something more interesting with it. And I started by installing a third party cooler. Now I don’t remember exactly what performance potential I was able to squeeze out, but I remember that it seemed insufficient to me. At some point, I opened the plastic cartridge of the slot processor and started experimenting with Peltier coolers to get more better cooling. In the end, I got a stable running processor at 400 MHz - at the same level as the most expensive models at the time, but significantly cheaper.

Of course, today overclocking gives a much more significant increase than 166 MHz. But the principles remain the same: we take a processor running at stock clock speeds, and then we squeeze the maximum out of it, trying to achieve the performance of high-end and more expensive models. With a little effort, you can quite easily get a sub-$300 Core i7-920 to perform at the $1,000 Core i7-975 Extreme performance without sacrificing reliability.

How about automatic overclocking?

Overclocking in general has always been a tricky issue for AMD and Intel, who don't officially support this practice, and void warranties if the CPU showed signs of tampering. However, in public, both manufacturers are trying to gain the trust of enthusiasts by offering overclocking utilities, supporting aggressive BIOS settings, and even selling processors with an unlocked multiplier. However, experienced users have always known that free cheese is only found in a mousetrap, so killing the CPU with too much voltage is an acceptable risk.

But with the advent of Turbo Boost technology on the Intel Core i7 processors for LGA 1366 and the subsequent release of a more aggressive implementation with the Core i5 and Core i7 processors for LGA 1156, Intel implemented its own smart overclocking technology that takes into account several different factors: voltage, current, temperature and P-states of the operating system associated with the load on the CPU.

By monitoring all of these parameters, the Intel Embedded Management System can improve performance by increasing the clock speed in situations where the maximum thermal package (TDP) of the processor is not reached. By turning off unused cores and thus reducing power consumption, the processor frees up more capacity for single-threaded workloads, a little less for two active threads, even less for three loaded cores, and so on. As a result, Intel's "automatic overclocking" is an elegant and consistent way to increase performance without exceeding the TDP of any given processor (130W for the Intel Bloomfield processor and 95W for the Lynnfield processor).

Can you do better?

When we discovered that the Core i7-860 and -870 processors accelerate to an impressive 667 MHz in single-threaded applications, we began to ask ourselves the question: should an advanced user overclock the processor themselves, risking ruining a good CPU, or can we just rely on Intel's dynamic overclocking ? No, we don't want to appear lazy. Let's hope that there really are tangible benefits for enthusiasts that provide better performance. But we still don't want to forget the efforts that Intel engineers made in trying to optimize Nehalem for balanced performance in single- and multi-threaded applications.

We decided on a little experiment: we took the Core i5-750 and Core i7-860 processors, overclocked each of them, and then compared the results of the two processors at stock frequencies with and without Turbo Boost technology turned off. Of course, we have Intel samples in our lab, but we cannot reliably consider them to be representative of retail models. So we bought both processors from Newegg just to make sure they match. We considered using the "box" Intel cooler, but in the end we figured that we would never get 4 GHz or more unless we purchased a third-party cooler. Therefore, for tests, we took the Thermalright MUX-120 model.

Getting ready for comparison

Processors

As already mentioned, we used retail versions of the Core i5-750 and Core i7-860 processors in our experiment, two models that seem to be of most interest to enthusiasts. The i5-750 is a $200 processor that can reliably run at 4GHz or higher, while the i7-860 is a $300 alternative with Hyper-Threading support, a base clock of 2.8GHz, and an additional Turbo Boost step on a single active thread .

Why didn't we take the Core i7-920 processor? This is also a very interesting option, especially if you're building a high-end gaming system and need the extra PCI Express 2.0 lanes that the Intel X58 chipset has. But at about the same price as the Core i7-860, the i7-920 processor adds a third memory channel, loses 133MHz of base clock speed, and provides a less aggressive Turbo Boost mode. In addition, buying a processor for LGA 1366 means purchasing an expensive Intel X58 motherboard. Lynnfield and P55 are more suitable for those enthusiasts who are interested in the optimal price / performance ratio of the new assembly.

Motherboard

Our choice of motherboard will puzzle some users, but we chose the Intel DP55KG for several reasons.

Let's start with the technical stuff: we originally planned to use our Asus Maximus III Formula motherboard. But after upgrading the board to latest version BIOS published on the company's website, it stopped working stably with our retail CPU and Corsair Dominator memory kit. We were probably just unlucky, so we took the Gigabyte P55A-UD6 motherboard, which worked fine with Turbo Boost enabled, but not so well with Turbo Boost disabled. The tests were successful, but when launching applications and while navigating Windows, it felt like we were not facing a powerful machine, but a ten-year-old Pentium II.

Therefore, in search simple solution, we switched to the Intel DP55KG motherboard, which performed well in last testing models on Intel P55. If so what motherboard and was supposed to work as expected, since this is Intel's own model aimed at enthusiasts. As you might expect, the Kingsburg motherboard did the job, so we continued with the tests.

Then we tried to eliminate bottlenecks. video card ATI Radeon The HD 5850 is great for the budget-conscious enthusiast, while the 160GB second-generation Intel SSD minimizes storage issues. Two 2GB Corsair DDR3-1600 Dominator GT DDR3-2200 8-8-8 modules allowed us to run DDR3-1600 clocks without any stability issues.

Test configuration

Tests and settings

Our first test results are already quite interesting. We observe that the Turbo Boost technology gives a minimal performance boost in the overall PCMark Vantage result. Meanwhile, overclocking leads to a significant gap between both processors. The Turbo Boost feature proved to be much more effective in both the TV and Movies and Productivity tests, although overclocking gives even more gains in both cases, as you might expect.

Interestingly, the Hyper-Threading technology provides a minimal advantage - we see this in all test runs of this package. Of course, this package relies on features built into Windows 7, so it's likely that operating system components aren't as well optimized for Hyper-Threading as Microsoft is trying to make us believe.

Turbo Boost technology has very little effect on the overall 3DMark Vantage results, but at least gives a tangible advantage in the CPU test. In GPU benchmarks, we don't see a noticeable effect. However, manual overclocking in GPU tests also has little effect. But this is not surprising. Both CPUs are fast enough not to bottleneck our single Radeon HD 5850 graphics card, so we expect very little performance gain in games after increasing the CPU clock speed.

This synthetic test showed a significant increase due to Hyper-Threading technology in the CPU run, which corresponds to the increase after manual overclocking, namely the quad-core i5-750 at 4 GHz equals the performance of the i7-860 at stock clock speeds with Turbo Boost. Well, we have yet to see how well these results will match real world applications.

The most significant increase after overclocking is observed in the Dhrystone iSSE4.2 test, where Hyper-Threading has little effect. In the Whetstone iSSE3 test, we see that the 4 GHz Intel Core i5-750 cannot reach the Core i7-860 running at the stock 2.8 GHz.

The multimedia benchmarks also show that Turbo Boost technology does not provide a significant boost, but we get a performance increase after overclocking both CPUs to 4 GHz. Hyper-Threading plays an important role in both test runs, which is also interesting since we expected Turbo Boost to have a more significant impact in the actual tests.

At stock clock speeds, memory bandwidth barely changes when Turbo Boost is turned on or off. This is because Turbo Boost only affects the processor multiplier, leaving the base clock speed BCLK unchanged (and therefore the memory divider does not change).

But when we overclock the processors by increasing the base BCLK frequency (since our CPUs have a locked multiplier), the memory bandwidth also increases, which we see in the SiSoftware Sandra 2010 Bandwidth test results.

We have updated our test suite to the latest version of Apple iTunes (9.0.2.25), but the behavior of the program has not changed. It is still poorly optimized for multithreading, so Hyper-Threading technology in this case only harms.

On the other hand, loading just one core causes Turbo Boost to noticeably improve performance in iTunes. The same can be said about the manual overclocking of both chips up to 4 GHz. It's nice to see that the theory is confirmed by practice.

Unfortunately, iTunes is the exception in our test suite, which is dominated by applications with good multithreading support. Let's see how they behave.

MainConcept can use as many threads as it has available. Even with Turbo Boost disabled, the Core i5-750 runs at 2.66 GHz, while the i7-860 runs at 2.8 GHz. Although this test stresses all four cores, running within the TDP and temperature limits means we get one step (133MHz) when Turbo Boost is enabled, which is why both processors perform better with this feature.

More than Turbo Boost, the Hyper-Threading feature gives the Core i7-860 a significant advantage over the i5-750 - good evidence that it really makes sense for multi-threaded applications to pay extra for the Hyper-Threading feature.

However, overclocking minimizes the difference between the two CPUs. At a frequency of 4 GHz, both processors cope with the work much faster than at standard frequencies. Of course, with the Core i5, we see a more significant percentage increase, since this processor does not receive multi-thread acceleration at stock frequencies due to the lack of Hyper-Threading.

Let's move on to the results of the DivX codec, which is well optimized for multithreading, as well as the Xvid codec, which is not so well optimized.

As you might expect, the Xvid codec does not provide an advantage (in fact, even loses) due to the active Hyper-Threading technology on the Core i7-860 compared to the Intel i5-750. However, Turbo Boost speeds up the execution of the task on both CPUs.

Interestingly, DivX doesn't benefit too much from Hyper-Threading either, suggesting a four-thread limit. In our case, the Core i7-860 is only slightly faster. And both processors get a substantial boost from overclocking - enough to say manual overclocking is in the best possible way to speed up performance in multi-threaded applications, and you will not get such a strong increase from Turbo Boost.

HandBrake is a new program in our test suite. This free utility, which can benefit from multithreading support. In our test, we converted the first .vob file of The Last Samurai movie to .mp4 format.

Since the utility supports multi-threading, the Turbo Boost function has little effect. But, again, it's interesting to see that Hyper-Threading does not have the same serious effect as, for example, we saw in the SiSoftware Sandra or 3DMark Vantage packages. The real way to increase performance is through manual overclocking - we get a significant performance improvement by increasing the frequency of our test CPUs to 4 GHz.

Our Adobe Photoshop CS4 test consists of several multi-threaded filters applied to a .TIF image. Therefore, it is not surprising that Turbo Boost technology has a minimal effect. Hyper-Threading is also not very noticeable.

But what really helps increase the performance of Photoshop CS4 is the clock speed. The Core i7-860 at 2.8 GHz performs slightly better than the Core i5-750 at 2.66 GHz, and Turbo Boost gives 133 MHz to both processors. At 4 GHz, both processors demonstrate comparable results, which are much higher than those without overclocking.

We were puzzled by the behavior of AVG 9 antivirus, which no longer scales so well after upgrading from AVG 8.5. However, starting the task manager during the test clarifies the situation. When the scanner is running, it consumes, at best, 10% of the processor resources. We tested the antivirus on dual-processor chips and on Atom platforms - performance really slows down if you reduce the number of cores and lower the clock speed. However, the Core i5-750 and Core i7-860 perform at a very close level, so we can say that their performance in AVG 9 is identical.

3ds Max 2010 benefits from both Hyper-Threading and Turbo Boost technologies. Overclocking remains the best way to get maximum performance in this program. The Core i5-750 shows an advantage at 4GHz due to its 200MHz BCLK base frequency, which is 10MHz higher than the i7-860's 190MHz at 4GHz.

This archiver is well optimized for multithreading (which cannot be said about Hyper-Threading support). WinRAR gives a minimal speed boost from Turbo Boost technology, since all four cores are active. Turning off Turbo Boost completely reduces the frequency of each CPU by 133 MHz at full load, so this technology still helps a little.

However, when both processors operate at 4 GHz, the performance is comparable (and significantly faster than at stock frequencies).

As you can see, the compression speed (in KB/s) scales proportionally not only to the clock speed, but also to the number of available cores. In fact, the 4GHz Core i5-750 can't even reach the 2.8GHz Core i7-860 with Turbo Boost disabled.

Since this archiver is well optimized for multithreading, Turbo Boost has little effect. Hyper-threading adds a bit of performance, and overclocking again gives a serious victory.

3D games

Crysis at all three resolutions tested showed negligible gains from Turbo Boost, Hyper-Threading, or overclocking.

This game appeared in our test package recently. Unlike Crysis, which heavily loads the graphics subsystem, Left 4 Dead 2 scales more efficiently with CPU performance (assuming you have a graphics card as powerful as our Radeon HD 5850, of course).

We can see that the 133 MHz auto-boost due to Turbo Boost technology helps a little at low resolutions, but Hyper-Threading doesn't affect it at all. Overclocking gives a noticeable increase in resolutions of 1680x1050 and 1920x1200. However, all these gains are no longer observed, it is worth turning on anti-aliasing and anisotropic filtering. As with Crysis, performance starts to level off whether your system is running a Core i5-750 at 2.66GHz or a Core i7-860 at 4GHz.

We will not conduct a full set of gaming tests, since there is no point. In our third and final Call of Duty Modern Warfare 2 gaming test, we see that CPU performance doesn't always match gaming performance. This popular game is not the best option to test, but a 60-second run of Act II: The Gulag shows us that Turbo Boost, Hyper-Threading, and even overclocking to 4 GHz does not lead to an increase in frame rates.

Now comes an interesting moment. If it were possible to set all processors to run up to 4 GHz without changing all other variables, then our recommendations based on benchmark tests would already be obvious. Alas, this is not so.

The good news is that you can increase the voltage on each processor, increase their frequency to 4 GHz, and then get quite a modest idle power consumption. The Enhanced SpeedStep technology was implemented properly on the Intel DP55KG motherboard even when the base BCLK frequency was set to 200 or 190 MHz, which means that both of our test processors dropped clock speeds without load. Of course, we see a slight increase in power consumption in both cases, but it is two or three watts, which can be ignored.

The PCMark Vantage run graph on the Intel Core i5-750 shows a completely different picture when the processor is running under load. On the graph you will find three lines: the green one represents our i5-750 run with Turbo Boost completely disabled, the red one is the power consumption with Turbo Boost enabled, and the blue one is the power consumption of the platform when the processor is overclocked to 4 GHz using a base frequency of 200 MHz BCLK and voltage 1.45 V.

It is quite clear that the inclusion of Turbo Boost leads to an increase in power consumption. But it's much lower than the overclocking and voltage boost required to keep our 2.66GHz processor stable at 4GHz.

Average power consumption without Turbo Boost was 115W for the entire run. After turning on Turbo Boost, the average power consumption increased to 120 watts. After overclocking to 4 GHz, it increased to 156 watts, and at the same time we finished the test just 28 seconds faster.

Conclusion

As a result, our study of the benefits of Turbo Boost, Hyper-Threading and good old overclocking gave us something to think about.

The first thing we learned is that Turbo Boost technology is most effective at improving the performance of applications that are poorly optimized for multithreading. Today, there are fewer and fewer such applications, but we still have a couple of programs that get a serious performance boost after turning on Turbo Boost. We also noticed a constant small boost after turning on Turbo Boost, even in multi-threaded applications, which is associated with one step of acceleration when using four cores. All in all, the intelligent overclocking built into the Nehalem design processors gives Intel a competitive advantage over AMD and its own Core 2 line in applications like iTunes, WinZip and Lame. Turbo Boost no longer affects the performance of MainConcept, HandBrake, WinRAR and 7zip - efficiently written applications that can fully load quad-core processors due to their parallelism.

Hyper-Threading makes even less sense, but, again, we can give a couple of examples where this technology performs well in real conditions. Video transcoding applications, for example, can take advantage of Hyper-Threading and reduce task execution time. That said, there's every reason why we'd recommend the Core i5-750. This processor costs nearly $100 less than the Core i7-860, yet delivers nearly the same level of performance with minimal impact in properly optimized programs. Before us is a kind of modern version of the famous Celeron 300A, which worked reliably at 450 MHz.

The biggest victory was still won by manual overclocking. Of course, we appreciate the new Turbo Boost feature in the Core i5 and Core i7 processors, but it's important to emphasize that the benefit of this technology is most apparent in single-threaded applications (and this benefit is slowly fading away as developers begin to fully use modern multi-core architectures). If the load on the processors is full, then the advantage of Turbo Boost is no longer so significant. Meanwhile, the boost that overclocking provides shows itself constantly, regardless of whether you fire up iTunes or HandBrake. And today is a great time to become an overclocking enthusiast: affordable 45nm processors can easily be overclocked to 4GHz, and recently released 32nm processors can be overclocked to 4.5GHz and higher.

Of course, there are some subtleties associated with changing the standard parameters. First, risk must be considered. Running a processor at 4 GHz at 1.45 V is not that dangerous (even with air cooling), but if the processor burns out, then you cannot replace it under warranty. Moreover, power consumption under load increases significantly if you increase the clock frequency and voltage. Luckily, the motherboard we were using correctly reduced power consumption and clock speed during inactivity.

Finally, we should remind our readers that it does not make much sense for a gamer to invest in an expensive processor. From a $200 Core i5-750 to a $300 Core i7-860, you'll get the same frame rate at most resolutions unless you invest in a more expensive graphics card configuration.

Rizabek Khalikov you are so funny))
Turbo Boost is Intel's technology to automatically increase a processor's clock speed beyond its rated speed, as long as the TDP power, temperature, and current limits are not exceeded. This results in performance improvements for single-threaded and multi-threaded applications. In fact, this is the technology of "self-acceleration" of the processor.

Answer from cactus i[guru]
it turns itself on. it's a type of auto acceleration

Answer from Ale3x[active]
should turn on itself if the processor resources are not fully used

Answer from Alexander[guru]
Intel® Turbo Boost Technology is usually enabled by default in one of the bios menus. Other than using the BIOS menu, there is no way for the user to change how Intel® Turbo Boost Technology works through hardware or operating system settings. When Intel® Turbo Boost Technology is enabled, it runs automatically under the operating system.

Answer from Artem Morozov[guru]
when you start the application, it turns on by itself (depending on the power of the application)

Answer from Egor[guru]
Turbo boost rated power (TDP). This results in performance improvements for single-threaded and multi-threaded applications. In fact, this is the technology of "self-acceleration" of the processor.
The availability of Turbo Boost technology is independent of the number of active cores, but is dependent on the presence of one or more cores operating at less than rated power. System Turbo Boost time varies depending on workload, operating conditions, and platform design.

Answer from Master of Zelenka[guru]
Turboboost was created in order to adjust the processor to applications.

Answer from Butt Head[newbie]
How to enable Turbo Boost?
It is already enabled by default.
How to turn off Turbo Boost?
To disable it, you need to change the maximum state of the processor in the current power plan.
Control Panel --> Hardware and Sound --> Power Options --> Set up a power plan --> Change advanced power settings --> Processor power management:
Maximum processor state: from the network and battery, set the value below 100 (to disable, just set 99).
Minimum processor state: also check that the value is below 100.
That is, if it costs 100 - turbo boost is enabled. If less than 100 - disabled.
