About

What is Intel® Turbo Boost Technology? Intel® Turbo Boost Technology is a way to automatically run the processor core faster than the noted frequency. The processor must work in the power, temperature, and specification limits of the thermal design power (TDP). Single and multi-threaded application performance increase.
What's the difference between the original implementation of Intel® Turbo Boost Technology and Intel® Turbo Boost Technology 2.0?Intel® Turbo Boost Technology 2.0 introduces new power efficiencies using an integrated die for processor and graphics.
What's the difference between Intel® Turbo Boost Technology 2.0 and Intel® Turbo Boost Max Technology 3.0? Intel® Turbo Boost Technology 3.0 allows you to direct workloads to the fastest core. It requires an enabled BIOS/ firmware, a supported processor, and software to successfully implement the technology. See the Intel® Turbo Boost Max Technology 3.0 section below for more information regarding specific requirements.

Support

Which processor families support Intel® Turbo Boost Technology? Intel® Core™ i5 Mobile and Desktop Processors
Intel® Core™ i7 Mobile and Desktop Processors
Intel® Core™ i7 Desktop Processor Extreme Edition
Intel® Core™ i7 Mobile Processor Extreme Edition
Intel® High End Desktop Processors

 
Which operating systems does Intel® Turbo Boost Technology support? Intel® Turbo Boost Technology is a processor technology that is operating system independent. See the Intel® Turbo Boost Max Technology 3.0 section to see the operating systems requirements that are specific to this technology.
Does my motherboard support Intel® Turbo Boost Technology?

Intel® Turbo Boost Technology is a processor technology. Make sure you have an Intel® Turbo Boost Technology supported processor. Desktop board vendors normally enable Intel® Turbo Boost Technology by default. You can typically enable or disable through a switch in the desktop board BIOS.

See your motherboard documentation or vendor website for more information.

Operation

What factors influence Intel® Turbo Boost Technology operation?Operation depends 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 can I enable or disable Intel® Turbo Boost Technology? Intel® Turbo Boost Technology is typically enabled by default. You can only disable and enable the technology through a switch in the BIOS. No other user controllable settings are available. Once enabled, Intel® Turbo Boost Technology works automatically under operating system control.
Can I enable or disable Intel® Turbo Boost Technology by core? No. Intel® Turbo Boost Technology is a processor technology. As long as one core is active, the technology is enabled.

Intel® Turbo Boost Max Technology 3.0 does allow you to designate the fastest core to certain applications but is enabled only for Intel® Core™ i7-68xx / i7-69xx Processors. See the "Intel® Turbo Boost Max Technology 3.0" section for more information on technology requirements.

How important is system integration and system design regarding Intel® Turbo Boost Technology? Intel® Turbo Boost Technology runs when the processor is working within the power, temperature, and specification limits of thermal design power (TDP). Good system integration and thermal design are both critical for extracting the benefits of Intel® Turbo Boost Technology.

Turbo Boost frequency

Can I see frequency tables for Intel® Core™ i5, Intel® Core™ i7, and Intel® Core™ i7 Extreme Edition desktop processors? The charts show how Intel® Turbo Boost Technology works across processor cores with adequate power, temperature, and current headroom:

Can I specify the maximum Intel® Turbo Boost Technology frequency? No. Maximum frequency for processor function is automatic and dependent on working conditions.

Intel® Turbo Boost Max Technology 3.0

What is Intel® Turbo Boost Max Technology 3.0 and how does it work? Intel® Turbo Boost Max Technology 3.0 uses a driver coupled with information stored in the CPU to identify and direct workloads to the fastest core on the die first. The driver also allows for custom configuration via a list that gives end users the ability to set priority to preferred applications. The driver MUST be present on the system and configured correctly, as current operating systems cannot effectively route workloads to ordered cores.
