But its max turbo frequency is much faster: 5.3 GHz. It’s the maximum single-core frequency a CPU achieves without overclocking.įor example, the Intel® Core™ i9-11900K has a base frequency of 3.5 GHz, meaning it completes 3.5 billion cycles per second. Max turbo frequency is the frequency a CPU targets when stressed by a demanding application like a game.

Operating at a lower frequency some of the time - as opposed to full speed all of the time - can also aid processor longevity 4. When running at its base frequency, the CPU draws less power and produces less heat. They do this by increasing the CPU’s frequency, or clock speed.īefore we discuss how boosting behaviors work, there are two specifications to understand.īase frequency is the frequency at which the CPU runs when the system is idle or under light load. But heavyweight tasks like gaming, editing video, or streaming content are more taxing.īoost technologies address this difference and help Intel processors adapt to the job at hand. Typically, processors can easily handle lightweight requests like running a word processor or browsing the web. Microsoft makes no warranty, implied or otherwise, about the performance or reliability of these products.Different workloads place different demands on a system’s CPU. The third-party products that this article discusses are manufactured by companies that are independent of Microsoft. And Turbo Boost drives the processor above 100% of its nominal speed, and allows the processor to exceed 100% capacity. With the redesigned Task Manager, the first processor is shown to be running at 50% capacity, whereas the second processor is shown to be running at 100% capacity. Both appear to be doing the same amount of work: 100% of their capacity.

Before this change, under the time-based performance counters (used in Windows 7 Task Manager), those two processors clocked differently. A processor that's running 50% of the time and clocked down to 50% frequency performs only half the work of a processor that's running 100% of the time at 100% frequency. This change was intended to provide a more accurate representation of how much work the system is handling, and the utility counters do just that. The utility performance counters take into account the processor performance state and Turbo Boost-based enhancements to measure and normalize the work that's being done by the CPU. The time-based performance counters measure the percentage of time that the processor is busy, whereas the utility performance counters measure how much work the processor actually performs. The difference between the two counter types concerns how they measure the actual work that the processor performs.
The values in Task Manager now correspond to the Processor Information% Processor Utility and Processor Information% Privileged Utility performance counters, not to the Processor Information% Processor Time and Processor Information% Privileged Time counters as in Windows 7. This change affects the way that CPU utilization is computed.
With this change, CPU utilization may appear to exceed 100% when the system is under a heavy load, especially when capacity is boosted by Intel Turbo Boost. Starting with Windows 8, a change was made to the way that Task Manager and Performance Monitor report CPU utilization.

This article describes an issue where CPU usage exceeds 100% in Task Manager and Performance Monitor if Intel Turbo Boost is active.Īpplies to: Windows 8 Original KB number: 3200459 Symptoms
