The CPU core voltage (V CORE) is the power supply voltage supplied to the processing cores of CPU (which is a digital circuit), GPU, or any other device with a processing core. The amount of power a CPU uses, and thus the amount of heat it dissipates, is the product of this voltage and the current it draws.
Haswell featured a FIVR.. Most voltage regulator module implementations are soldered onto the motherboard.Some processors, such as Intel Haswell and Ice Lake CPUs, feature some voltage regulation components on the same CPU package, reduce the VRM design of the motherboard; such a design brings certain levels of simplification to complex voltage regulation involving numerous CPU supply voltages ...
When the logic gates toggle, energy is flowing as the capacitors inside them are charged and discharged. The dynamic power consumed by a CPU is approximately proportional to the CPU frequency, and to the square of the CPU voltage: [5] = where C is the switched load capacitance, f is frequency, V is voltage.

Original IBM power supplies for the PC (model 5150), XT and AT included a line-voltage power switch that extended through the side of the computer case. In a common variant found in tower cases, the line-voltage switch was connected to the power supply with a short cable, allowing it to be mounted apart from the power supply.
A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
In November 2010, IBM machine, Blue Gene/Q achieves 1,684 MFLOPS/watt. [8] [9] On 9 June 2008, CNN reported that IBM's Roadrunner supercomputer achieves 376 MFLOPS/watt. [10] [11] As part of the Intel Tera-Scale research project, the team produced an 80-core CPU that can achieve over 16,000 MFLOPS/watt. [12] [13] The future of that CPU is not ...
Fully integrated voltage regulator (FIVR), thereby moving some of the components from motherboard onto the CPU. [ 37 ] [ 38 ] [ 39 ] New advanced power-saving system; due to Haswell's new low-power C6 and C7 sleep states, not all power supply units (PSUs) are suitable for computers with Haswell CPUs.
LGA 1150 features a Fully Integrated Voltage Regulator.. LGA 1150, [1] also known as Socket H3, is a zero insertion force flip-chip land grid array (LGA) CPU socket designed by Intel for CPUs built on the Haswell microarchitecture.
