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 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 feature is designed to increase performance of both multi-threaded and

single-threaded workloads.

Maximum frequency is dependant on the SKU and number of active cores. No special

hardware support is necessary for Intel Turbo Boost Technology. BIOS and the

operating system can enable or disable Intel Turbo Boost Technology.

Compared with previous generation products, Intel Turbo Boost Technology 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 may not be available on all SKUs.

The processor rated frequency assumes that all execution cores are running an

application at the thermal design power (TDP). However, under typical operation, not

all cores are active. Therefore, most applications are consuming less than the TDP at

the rated frequency. To take advantage of the available thermal headroom, the active

cores can increase their operating frequency.

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

takes the following into consideration:

•

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.

Any of these factors can affect the maximum frequency for a given workload. If the

power, current, or thermal limit is reached, the processor will automatically reduce the

frequency to stay within its TDP limit. Turbo processor frequencies are only active if

the operating system is requesting the P0 state. For more information on P-states and

Intel Advanced Vector Extensions 2.0 (Intel AVX2) is the latest expansion of the Intel

instruction set. Intel AVX2 extends the Intel Advanced Vector Extensions (Intel AVX)

with 256-bit integer instructions, floating-point fused multiply add (FMA) instructions,

and gather operations. The 256-bit integer vectors benefit math, codec, image, and
