Intel Turbo Boost Technology is a feature found in Intel processors that allows the CPU to automatically increase its clock speed beyond its base clock speed in order to provide better performance when needed. The technology works by monitoring the workload of the processor and increasing the clock speed of the cores that are in use. This can result in a significant increase in performance for applications that require high CPU usage, such as gaming, video editing, or 3D rendering.
When Turbo Boost is enabled, the processor can adjust its clock speed dynamically based on the workload, and can increase the clock speed up to a certain limit, depending on the processor model and the cooling capabilities of the system. The maximum clock speed achievable with Turbo Boost can vary depending on the number of cores in use, the thermal conditions of the system, and the power delivery capabilities of the motherboard.
Overall, Intel Turbo Boost Technology is a useful feature that can help provide better performance in demanding applications, and is present in many modern Intel processors, including the Core i5-6200U found in the HP EliteBook 840 G3.
