Dynamic voltage scaling to increase voltage is known as overvolting; dynamic voltage scaling to decrease voltage is known as undervolting. Undervolting is done in order to conserve power , particularly in laptops and other mobile devices , where energy comes from a battery and thus is limited, or in rare cases, to increase reliability.
Underclocking, also known as downclocking, is modifying a computer or electronic circuit's timing settings to run at a lower clock rate than is specified. Underclocking is used to reduce a computer's power consumption, increase battery life, reduce heat emission, and it may also increase the system's stability, lifespan/reliability and compatibility.
Both Intel and Advanced Micro Devices (AMD) have defined TDP as the maximum heat generation for thermally significant periods, while running worst-case non-synthetic workloads; thus, TDP is not reflecting the actual maximum power of the processor. This ensures the computer will be able to handle essentially all applications without exceeding ...
The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.

Some users and game developers have worked around the problem by applying lower power limits, undervolting or underclocking the CPU. As of April 18, 2024, according to Intel an investigation of the root cause of the instability issues was underway. [36]
Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors (Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors , from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model .
Intel was expected to release 17 Broadwell U series family microprocessors at CES 2015. [50] Also, according to a leak posted on vr-zone, Broadwell-E chips would be available in 2016. [51] On August 11, 2014, Intel unveiled formally its 14 nm manufacturing process, and indicated that mobile variants of the process would be known as Core M ...
