The 800Mhz is a theoretical value that cannot always be achieved but it will run at a frequency arbitrarily close to that. To save power when in the OS and the system is idling (low processor load), the processor will attempt to clock down to its minimum base clock speed of 800Mhz.

The maximum frequency the BIOS can clock the processor to is 3.3Ghz.

3.10Ghz is what the BIOS is currently clocking the processor to.

This is the base frequency of the I7-4940 The Intel I7-4940, for example, would display the following characteristics in a Precision M6800: When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase until the upper limit of frequency is reached.Ī system that supports Turbo Boost Technology may be marketed with the maximum boosted processor speed listed, but when the system is not requesting maximum performance, or when viewed in the BIOS, the processor speed will be reported as the un-boosted default speed. NOTE: Due to varying power characteristics, some parts with Intel Turbo Boost Technology may not achieve maximum turbo frequencies when running heavy workloads and using multiple cores concurrently.Īvailability and frequency upside of Intel Turbo Boost Technology state depends upon a number of factors including, but not limited to, the following: Intel Turbo Boost Technology frequency varies depending on workload, hardware, software, and overall system configuration.

Maximum turbo frequency indicates the highest possible frequency achievable when conditions allow the processor to enter turbo mode. The processors' performance states are defined by the Advanced Configuration and Power Interface (ACPI) specification. Intel Turbo Boost Technology is activated when the operating system requests the highest performance state of the processor.

Decreasing frequency reduces heat and power consumption. Exceeding the frequency design limit on a processor increases power consumption and heat output. Overclocking is the term used to describe raising the Core Clock beyond the processors designed frequency limit and increasing the speed of the processor. Changes to the Core Clock raises or lowers the Frequency of the processor and thus the speed of the processor. The frequency of the Hertz is defined by the Core Clock. NOTE: The speed of a processor is measured in Hertz.
