Intel recommends enabling Intel HT Technology with Microsoft Windows* 8 and

Microsoft Windows* 7 and disabling Intel HT Technology using the BIOS for all

previous versions of Windows* operating systems. For more information on Intel HT

The Intel Turbo Boost Technology 2.0 allows the processor core to opportunistically

and automatically run faster than its rated operating frequency/render clock, if it is

operating below power, temperature, and current limits. The Intel Turbo Boost

Technology 2.0 feature is designed to increase performance of both multi-threaded

and single-threaded workloads.

The processor supports a Turbo mode in which the processor can use the thermal

capacity associated with the package and run at power levels higher than TDP power

for short durations. This improves the system responsiveness for short, bursty usage

conditions. The turbo feature needs to be properly enabled by BIOS for the processor

to operate with maximum performance. Since the turbo feature is configurable and

dependent on many platform design limits outside of the processor control, the

maximum performance cannot be ensured.

Turbo Mode availability is independent of the number of active cores; however, the

Turbo Mode frequency is dynamic and dependent on the instantaneous application

power load, the number of active cores, user configurable settings, operating

environment, and system design.

Compared with previous generation products, Intel Turbo Boost Technology 2.0 will

increase the ratio of application power to TDP. Thus, thermal solutions and platform

cooling that are designed to less than thermal design guidance might experience

thermal and performance issues since more applications will tend to run at the

maximum power limit for significant periods of time.

Intel Turbo Boost Technology 2.0 may not be available on all SKUs.

The processor rated frequency assumes that all execution cores are active and are at

the sustained thermal design power (TDP). However, under typical operation not all

cores are active or at executing a high power workload. Therefore, most applications

are consuming less than the TDP at the rated frequency. Intel Turbo Boost Technology

2.0 takes advantage of the available TDP headroom and active cores are able to

increase their operating frequency.

To determine the highest performance frequency amongst active cores, the processor

takes the following into consideration to recalculate turbo frequency during runtime:

•

The number of cores operating in the C0 state.

•

The estimated core current consumption.

•

The estimated package prior and present power consumption.

•

The package temperature.
