What is Intel Turbo Boost? How does Intel Turbo Boost work?

Processors in laptops or desktops have standard clock speeds. The CPU will periodically lower the clock speed to save energy, especially on laptops.

But did you know that the CPU can also periodically activate the Turbo Boost mode to provide some additional processing?

Intel Turbo Boost Technology and AMD Turbo Core can automatically speed up the CPU, depending on the thermal headroom (the difference between the normal temperature and the maximum temperature where the device can still operate normally) available.

So how does Intel Turbo Boost work? How to activate Intel Turbo Boost? The answer will be in the following article.

What is Intel Turbo Boost? How does Intel Turbo Boost work? Intel Turbo Boost is a feature available for Core i3, Core i5, Core i7 and Xeon CPUs

Intel Turbo Boost monitors CPU usage Intel Core to determine how close the processor is to maximum heat dissipation (TDP). If Intel Turbo Boost technology finds that the CPU performs well within the limits, then Turbo Boost can start working.

Intel Turbo Boost is a feature available for Core i3, Core i5, Core i7 and Xeon CPUs. Not all Intel CPUs have Turbo Boost, although this is a common feature for most CPUs manufactured since 2008.

There is no fixed speed that the processor will reach in Turbo Boost mode. However, there is Maximum Turbo Frequency that defines the absolute limit the CPU will reach. For example, the Intel Core i5-9600K has a Processor Base Frequency of 3.70GHz and the Max Turbo Frequency of 4.60GHz. Turbo Boost can provide additional processing power up to 0.9GHz.

Furthermore, the CPU Turbo Boost doesn't push the processor straight from 3.70GHz to 4.60GHz, but it will increase it slowly.

In fact, Intel still advertises these processors with base clock speeds. This is because Intel does not guarantee that the processor will reach maximum Turbo Boost speed. Whether or not Turbo Boost is maxed out depends on the workload, so the results aren't always the same.

Why does Turbo Boost help achieve high performance?

Turbo Boost is a core Intel CPU feature. The operation of Turbo Boost is unpredictable. However, it brings great processing power boost to the CPU.

Before Turbo Boost, the choice of whether to buy a dual-core or a quad-core processor was a headache. Many dual-core processors have faster clock speeds than quad-core processors, simply because having multiple cores increases power consumption and heat generation.

Some programs, such as games, favor dual-core processors, while others, like 3D rendering software, are more quad-core. If you use both types of applications, you are forced to make a choice and not get the maximum performance out of both programs from one processor.

The advent of Turbo Boost has changed everything.

Modern Intel CPUs with Turbo Boost technology all have different strengths and weaknesses. You can use Intel CPUs with 3D rendering apps, high-performance games, video editing, and more and know that Turbo Boost will provide more processing power where possible.

Does Turbo Boost affect laptop battery life?

Increased processing power means more power consumption. On desktops, the Intel Turbo Boost's increased power needs should not be an issue. Meanwhile, if you use a laptop with limited battery life, Turbo Boost will affect your device's battery life.

However, determining the exact impact of CPU Turbo Boost on laptop battery is difficult. This is mainly because there is a lot of CPU and battery combination.

There are two options available to disable Turbo Boost on laptops. First you should check the specific Turbo Boost switch in the system BIOS. From here, you can enable or disable Turbo Boost, depending on how much performance you require.

If that option is not available, you should consult the guide to undervolt lowering CPU temperature.

How to enable Intel Turbo Boost

If you are wondering how to enable Intel Turbo Boost, you don't need to worry about this. The computer will use Turbo Boost automatically. Some system BIOS will let you enable or disable Turbo Boost, others won't.

Chances are you are using Intel Turbo Boost all the time without realizing it.

As mentioned in the above section, there are a number of reasons why you might consider disabling Turbo Boost. But you should only do it if you have no other choice.
