Thermal Specifications

The number of cores operating in the C0 state.

The estimated current consumption.

The estimated power consumption.

The 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 with its TDP limit.

Note: Intel Turbo Boost Technology processor frequencies are only active if the operating system is requesting the P0 state.

6.3.2Intel® Turbo Boost Technology Graphics Frequency

Graphics render frequency is selected by the processor dynamically based on the graphics workload demand. The processor can optimize both processor and integrated graphics performance through managing total package power. For the integrated graphics, this could mean an increase in the render core frequency (above its base frequency) and increased graphics performance. In addition, the processor core can increase its frequency higher than it would without power sharing.

Enabling Intel® Turbo Boost Technology will maximize the performance of the processor core and the graphics render frequency within the specified package power levels. 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.

6.4Thermal Considerations

Intel Turbo Boost Technology allows processor cores and Processor Graphics cores to run faster than the baseline frequency. During a turbo event, the processor can exceed its TDP power for brief periods. Turbo is invoked opportunistically and automatically as long as the processor is conforming to its temperature, power delivery, and current specification limits. Thus, thermal solutions and platform cooling that are designed to be less than thermal design guidance may experience thermal and performance issues since more applications will tend to run at or near the maximum power limit for significant periods of time.
