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 Technology, see
3.4Intel® Turbo Boost Technology
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
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.
Note: Intel Turbo Boost Technology may not be available on all SKUs.
Intel® Turbo Boost Technology Frequency
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
