Intel Turbo Boost
TLDR: Intel Turbo Boost is a dynamic overclocking technology introduced by Intel in 2008 with the Nehalem microarchitecture. It allows Intel CPUs to increase their clock rate beyond the base frequency to enhance performance during demanding workloads. By monitoring power, current, and thermal headroom, Intel Turbo Boost adjusts core speeds dynamically, enabling efficient use of available resources for tasks that require extra computational power.

Intel Turbo Boost operates by increasing the clock rate of one or more cores when the workload demands higher performance and the processor operates within its power and thermal limits. For example, a CPU with a base frequency of 2.9 GHz and a Turbo Boost frequency of 4.2 GHz can temporarily run at the higher speed for tasks such as video encoding, gaming, or data processing. This technology is particularly beneficial for single-threaded applications that rely heavily on individual core performance.

The efficiency of Intel Turbo Boost is enhanced by its integration with other technologies like Intel Hyper-Threading and power management frameworks. Modern processors include advanced versions, such as Intel Turbo Boost Max Technology 3.0, which prioritizes the fastest cores for critical workloads. While Intel Turbo Boost improves performance, it can also increase power consumption and heat generation, requiring adequate cooling systems to maintain optimal operation.
