Intel users want to know, What Does Intel Speed Shift Do? Now that it’s accessible. Read it to find out the answer! The Intel architecture includes power-saving technologies like speed step and speed shift. As described farther down.

Personally, I advocate leaving Speed step enabled (even on overclocked systems) and Speedshift off, because I’ve seldom seen Speed shift work right in the first place, and Speed step is an important aspect of the Intel processor architecture’s power and thermal management activities.

What Does Intel Speed Shift Do?

Intel Speed Shift technology, also known as HWP (Hardware p-state) or Hardware Controlled Performance, allows the processor to select the appropriate operating frequency and the voltage more quickly for optimal efficiency and energy efficiency with short-duration performance adjustments.

Intel Speed Shift

Intel Speed Shift, also called as HWP (Hardware p-state) or Hardware Controlled Performance, allows the processor to more instantly choose operating frequency and voltage for excellent performance and power efficiency via short-duration performance shifts.

Instead of lingering at lower frequencies waiting for the OS to convey commands through a translation layer, the ability to swiftly ramp up performance is used to improve overall system responsiveness.

Speed Shift cannot boost absolute maximum performance, but it can make a significant difference in how quickly a task is completed under short workloads that demand a burst of performance.

In the end, much of what we do, such as web browsing or office work, falls into this group. Web browsing, for example, is all about getting the page loaded quickly and then returning the CPU to idle.

Intel was able to offer us the Windows 10 Speed Shift patch ahead of time for this short article, allowing us to test and see what kind of gains it may achieve. This puts us in a unique position since we can isolate this one variable on a new CPU and test its influence on diverse workloads.

Speed Step

Enhanced Intel SpeedStep Technology allows the system to modify the processor voltage and core frequency dynamically, lowering average power consumption and heat production. System builders can potentially reduce acoustics by reducing power and heat on desktop PCs or any laptop, depending on system choices.

They can also create smaller form factor designs that are more inventive. The function also aids organizations with facilities approaching the boundaries of constrained electrical networks in addressing power challenges.

Enhanced Intel SpeedStep Technology, when combined with other power-saving features, can help achieve a balance between power production and consumption. It employs a variety of design strategies, including the following:

Changes in voltage and frequency are separated. The CPU can lessen periods of system unavailability by stepping voltage up and down in modest amounts apart from frequency changes (which occur during frequency change). The system may switch between voltage and frequency states more often, improving the power-to-performance ratio.

Partitioning and recovery of clocks: When the core clock and phase-locked loop are turned off during state transition, the bus clock continues to run. Logic is still active. Under Enhanced Intel SpeedStep Technology, the core clock can also restart faster than under previous architecture.

Enhanced Intel SpeedStep Technology decreases the latency of shifting the voltage/frequency pair (also known as P-state), so that those transitions can be made more often. Demand-based switching and adjustment of the power/performance balance may now be done at a finer level.

Intel has retired SpeedStep in favor of the brand new Speed Shift technology, which allows for better CPU frequency control. Most Intel-based PCs use Intel’s Speed Step technology, which uses P-states, which are performance states that the operating system can request from the processor.

When a processor receives a request, it normally adjusts its frequency and voltage levels to the point defined in the P-state at the start of the operation. Naturally, it is inefficient to run the CPU constantly at high clocks in situations where the heat envelope and electric consumption are confined (and even in situations where they are not), therefore the OS normally requests a lower P-state.

Difference Between Speed Step And Speed Shift

One of the most significant distinctions is that in Speed Step, the OS was primarily responsible for answering P-state requests, whereas, in Speed Shift, control would be returned to the CPU, resulting in vastly improved responsiveness. Let’s talk numbers for a moment.

When it comes to performance requests, the CPU generally responds in 20-30 milliseconds; however, with the new Speed Shift technology, this time will be lowered to roughly 1 millisecond – a substantial improvement. The time it takes to reach maximum performance is cut in half, from 100 to 35 milliseconds.

What Is Intel Speed Shift Technology?

Intel’s Speed Shift technology, also known as HWP (Hardware p-state) or Hardware Controlled Performance, enables the processor to select its ideal operating frequency and voltage more rapidly for optimal performance and power economy, resulting in faster response times over shorter periods.

Should I Enable Intel Speed Shift Technology?

Speed step is essential to the power and thermal management functions of Intel processor architecture. Hence I advise leaving it enabled (even on overclocked computers) and leaving Speed shift off. I’ve rarely seen the Speed shift work correctly.


By making story short What Does Intel Speed Shift Do? Speed Shift is a little element of the overall performance increase that we haven’t had the opportunity to examine till now. If the workloads are burst and brief enough to make a difference, it can result in significant increases in job completion.

It won’t enhance the processor’s absolute performance, but it will get it to maximum performance in a lot shorter time and return it to idle considerably faster. Improved responsiveness is what Intel claims, and it’s evident that they’ve done it.

Frequently Asked Questions

Is it necessary to disable Intel Speed Shift?

So it’s low when idle to save power, and as demand rises, it automatically raises its clock. With SpeedShift off, Windows handles the functionality instead of the CPU, which works fine. However, changing frequencies is slightly more subtle that way, so having SpeedShift enabled can make things feel more immediate.

Is it necessary to enable Intel Speedstep?

I would recommend leaving speedstep enabled unless you are conducting a short-term high overclock. This is not to say that deactivating speedstep will harm the CPU; it will just increase the amount of electricity used and the amount of heat produced, therefore the ordinary consumer should leave it enabled.

Does Speed Shift help you perform better?

Speed Shift cannot boost absolute maximum performance, but it can make a significant difference in how quickly a task is completed under short workloads that demand a burst of performance. In the end, much of what we do, such as web browsing or office work, falls into this group

Is Speed Shift a suitable gaming option?

EPP should be set to 0 for maximum CPU performance in High Performance, and 84 in Balanced. It doesn’t matter which one you use for gaming. In ThrottleStop, there’s no need to tick the SpeedShift EPP box. When gaming, gaming laptops with the 8750H tend to operate at 90°C.

Does Intel SpeedStep has an impact on performance?

Other than increasing the CPU’s performance based on load, speedstep has no influence on performance.

Is Turbo Boost the same as Intel SpeedStep?

Enhance when the processor is idle or under low demand, Intel SpeedStep Technology reduces the speed of the processor, allowing the system to save power. When the processor is under heavy strain, the Intel Turbo Boost technology allows it to increase the clock speed.

Does Speedstep take precedence over SpeedShift?

Is it true that because Speedshift is the latest one, it will automatically override Speedstep? Thanks. Speedshift takes precedence over SpeedStep. It makes no difference if SpeedStep is enabled or deactivated if Speed Shift is enabled, SST in green in ThrottleStop.
