What is Intel® Turbo Boost Technology and how does it work?

Intel® Turbo Boost Technology is a way to automatically run the processor core faster than the marked frequency. The processor must be working in the power, temperature, and specification limits of the thermal design power (TDP). This results in increased performance of both single and multi-threaded applications.

How many versions of Intel® Turbo Boost Technology are there?

Intel® Turbo Boost Technology has two versions. Intel® Turbo Boost Technology was originally introduced in late 2008 with the Intel® i7-9xx Processor Series. Intel® Turbo Boost Technology v2.0 was introduced in 2011 with the Intel® i5-2xxx and i7-2xxx Desktop Processors. Version 2.0 operates in the same fashion as the first implementation and was optimized for the new micro-architecture introduced at the time.

Which processor families support Intel® Turbo Boost Technology?

 

  • Intel® Core™ i7 Mobile and Desktop Processors
  • Intel® Core™ i7 Processor Extreme Edition
  • Intel® Core™ i7 Mobile Processor Extreme Edition
  • Intel® Core™ i5 Mobile and Desktop Processors
Intel® Turbo Boost Technology supports which Operation systems?

Intel Turbo Boost Technology is a processor technology, and is operating system agnostic.

What factors influence Intel® Turbo Boost Technology operation?

The operation is dependent on headroom available in one or more cores. The amount of time the system spends in turbo boost mode depends on workload, environment, and platform design.

How is Intel® Turbo Boost Technology enabled or disabled?

Intel® Turbo Boost Technology is enabled by default. You can disable or enable the technology with a switch in the BIOS. No other user controllable settings to change Intel Turbo Boost Technology operation are available. Once enabled, Intel Turbo Boost Technology works automatically under operating system control.

Is turbo frequency the same for all active cores in the processor?

Yes.

Can I enable or disable Intel® Turbo Boost Technology by core?

Intel® Turbo Boost Technology is a processor technology and cannot be enabled or disabled by core. If one core is active, the technology is enabled.

Can I specify the maximum Intel® Turbo Boost Technology frequency?

Maximum frequency for processor function cannot be specified. Maximum frequency is automatic and dependent on working conditions.

How can I tell if Intel® Turbo Boost Technology is working?

Download the Intel® Turbo Boost Technology Monitor. This application displays processor frequency activity for computers with processors that support Intel Turbo Boost Technology.

Note This software is not compatible with Intel® Core™ i3 Processors and 4th Generation Intel® Core™ Processors or higher. If installed on unsupported processors, the tool can display incorrect frequencies. In such cases, uninstall the application.
What is the difference between Intel® Turbo Boost Technology and Intel® Turbo Boost Technology Monitor?

Intel® Turbo Boost Technology is an Intel® processor technology while Intel Turbo Boost Technology Monitor is a tool that shows Intel Turbo Boost Technology in action.

How can I see the highest Turbo Boost frequency for my processor?

If you set the number of cores to one in the bios and run the Intel® Processor Identification Utility, it shows the highest Turbo Boost frequency. Make sure you reset the switch in the bios to reactivate all cores.

How important is system integration and system design in regard to Intel® Turbo Boost Technology?

Intel Turbo Boost Technology runs when the processor is working in the power, temperature, and specification limits of thermal design power (TDP). Good system integration and thermal design are crucial to extract the benefits of Intel Turbo Boost Technology.
