Basically it raises CPU operating frequency as well as performance in a dynamic non deterministic way. In fact, if some heavy lifting is required considering power usage Turbo Boost kicks in increasing CPU clock frequency for the duration of the task.īy setting TurboBoost index to its maximum value CPU will try to provide performance greater than the performance level corresponding to the Processor base frequency at all times. The index for this control works similar to Core parking.ĭuring the normal system load CPU in your system operates at a standard clock speed which indicates its overall performance. I hope this'll help explaining how it works.ĬPU frequency scaling is a feature that enables the operating system to scale CPU frequency up or down to try and match supply to demand, delivering CPU performance when necessary or saving energy when possible. This will tell the OS that it can only park 2 cores out of 6. Now for example we would like that 4 cores out of 6 to never be parked by the OS regardless of the load. Here's an example of how core parking actually works and the meaning of an index number. The functionality of this application allows for you to control the number of CPU cores that need to be enabled or disabled or you can simply enable all the cores at all times, see explanations on how it works below based on your personal requirements, also now by looking at CPU graph you can tell if the specific core is enabled or disabled.

The problem with Windows way of core parking is lack of flexibility since by default you are given very few options for setting Core parking index on your machine. Core parking can potentially increase energy efficiency during lower usage. The remaining cores are responsible for the remainder of the workload. Cores that are parked generally do not have any threads scheduled, and they will drop into very low power states when they are not processing interrupts, DPCs, or other strictly affinitized work. The PPM engine chooses a minimum number of cores for the threads that will be scheduled. Many features mentioned above will be described in greater details in the description below, so if you are interested read on The processor power management PPM engine and the scheduler work together to dynamically adjust the number of cores that are available to run threads.
This application was made to provide help in controlling such factors and reduce the effect of degrading performance when possible. This can be caused by many hard to predict factors, such as system state, availability, CPU state, heat and many many more. Even though these are all positive changes, it sometimes creates a situation where an end user is not getting top performance when it is required delayed performance boostboost. However, in the modern world, power consumption sometimes takes a higher priority than performance output. Back in a day, most computers were desktop machines with the main goal for the hardware, to offer absolute best performance and there was no real need for technologies such as SpeedStep, Turbo Boost etc.
Read information about your computer's hardware configuration, including the processor, the cache memory, the motherboard and the graphics card.

In the SPD section you can view information for each memory slot module size, maximum bandwidth, manufacturer, part numberand for the timings table frequency, voltagewhile Graphics allows you to view details on the GPU name, code name, technologyclocks core, shaders, memory and memory size, type, bus width. The Mainboard tab contains useful information regarding the motherboard such as manufacturer name and model, chipset and BIOS, while Memory lets you view various timings e. In the CPU section you can view data displayed on the processors such as name, code name, package, core voltage, specification and instructionsas well as clocks core speed, multiplier, bus speed and cache calculates the real latency of each cache memory level. Novice users are likely to get lost in the details, but power users are going to be thrilled. Moreover, you can directly run it from a removable drive. Since this is a portable product, the tool does not require any installation, so the Windows registry entries remain unchanged.
This way, avid gamers and users who generally put a strain on their systems can carefully supervise the capacities of their computers.
