CPU voltage specifications, is the low voltage version LV better, or is it better to be normal?

ZEn normal good,Generally speaking,The LV version of the low voltage consumes less power and has a long standby time,But because the voltage is low,The performance of the general CPU is not strong,Suitable for netbooks and other types,And the normal version is suitable for users who have requirements for performance,Which version to use depends on your needs,And the low voltage is not necessarily cheaper than the normal one,

Difference between CPU low voltage and standard voltage:

1.Low-voltage and standard-voltage naming is differentLow-voltage notebook CPUs often have U endings after their names, such as i5-4200U, while standard-voltage notebook CPUs usually end with M-endings, such as i5-3230M.

2.Low voltage and standard voltage consume different amounts of power.

The U-series low-power notebook processors typically consume 15W or 28W, while the standard voltage notebook has a power consumption of 35W or higher, and the low-power CPU can bring longer battery life.

3.Low voltage and standard voltage performance are different.

Low-power notebook processors tend to be clocked at less than 2GHz, while standard-voltage processors are usually clocked at more than 2GHz, and standard-voltage CPUs are one notch higher than low-voltage CPUs.

For example, the performance of the low-voltage notebook processor i5-4200U is basically equivalent to the performance of the fourth-generation standard voltage i3-3210mi processor, and the performance is basically reduced by one notch.

The CPU includes arithmetic logic components, register components, and control components.

Logical parts. English logic components; Operational logic components. You can perform fixed-point or floating-point arithmetic operations, shift operations, and logic operations, as well as address operations and transformations.

Register. Register components, including registers, special registers, and control registers. General-purpose registers can be divided into two types: fixed-point and floating-point, which are used to store the temporary storage of register operations and intermediate (or final) operation results during instruction execution.

The general-purpose register is one of the important components of the processor.

Control parts. control unit in English; The control component is mainly responsible for decoding the instructions and sending out the control signals for each operation to be performed to complete each instruction.

There are two kinds of structures: one is the microprogram control mode with micromemory as the core; One is the control mode based on the logical hard wiring structure.

Microcode is maintained in micromemory, and each microcode corresponds to one of the most basic microoperations, also known as microinstructions; Each instruction is composed of different sequences of microcode, and this sequence of microcodes constitutes a microprogram.

**After the processor decodes the instruction, it sends out a certain timing control signal, and executes a number of microoperations determined by these microcodes in the order of a given sequence with a microcycle as the beat, and the execution of a certain instruction can be completed.

Simple bending instructions are composed of (3 5) micro-operations, while complex instructions are composed of dozens or even hundreds of micro-operations.

1, CPU low voltage means that the TDP (thermal design power consumption) of the CPU is lower than 14W, 2, generally speaking, the CPU performance of the low-voltage version is low, the battery life is good, and the performance of the low-voltage version of the i5 processor and the standard version of the i3 processor is comparable.

3, behind the CPU with U is the low-voltage version For example, the full English name of i5-4200UTDP is "thermal design power", and the literal translation in Chinese is "thermal design power consumption". It is mainly used by computer system manufacturers, heatsink fan manufacturers, and chassis manufacturers for system design. Generally, TDP is mainly used in CPUs, and the CPU TDP value corresponds to the highest heat dissipation heat that the final version of the series CPU may achieve at full load (100% CPU utilization is theoretical), and the heatsink must ensure that the temperature of the processor is still within the design range when the processor TDP is maximum.

CPU low voltage means that the CPU works at low voltage, and the CPU is divided into low voltage version, standard pressure version, and high voltage version.

1. Low-voltage version: low power consumption, energy saving, low frequency, relatively low performance, the end of the computer CPU model is the letter U, that is, the low-voltage version of the CPU;

2. Standard pressure plate: that is, the normal version, normal frequency and power consumption, the performance is higher than that of the low-voltage version, and the end of the computer CPU model is the letter M, which is the standard pressure version of the CPU;

3. High-voltage version: It can be overclocked at high voltage, high frequency and high power consumption, and the performance is higher than that of the standard pressure version, and the end of the computer CPU model is the letter H for the high-voltage version of the CPU.

Low-voltage CPU is a low-voltage version of the CPU, which has the advantages of low power, low heat generation, and long standby time, and is generally used in portable devices or laptops.

This is generally used on notebooks, the ultra-low-end voltage version of the CPU has low power consumption and low heat generation, which is more suitable for notebooks that need to be on standby for a long time and have relatively low performance requirements, most of these are ultra-thin ultrabooks, the disadvantages of this type of CPU are low frequency, low performance, and slow speed, so it is not very suitable for playing games or professional graphics, if it is only used for watching movies, processing documents, and listening** Then it is quite good to buy a notebook with an ultra-low voltage version of the processor, and this kind of notebook looks very beautiful The body is thin and light, and the shape is stylish.

The main differences between the low voltage and the standard voltage of the CPU are in terms of naming, power consumption, performance, etc. In general, the low voltage will not affect the normal use, the standard voltage CPU will be better than the low voltage CPU in terms of performance, if you play large games, etc., the performance requirements are relatively high, it is recommended to use the standard voltage CPU.

Naming: Low-voltage notebook CPUs often have U endings after their names, such as i5-4200u, while standard voltage notebook CPUs are usually named with M endings, such as i5-3230M.

Power consumption cores: The power consumption of U-series low-power notebook processors is usually 15W or 28W, while the power consumption of standard voltage notebook laptops is usually 35W or higher, and low-power CPUs can bring longer battery life.

Performance: Low-power notebook processors often have a frequency of less than 2GHz, while standard voltage processors usually have a frequency of more than 2GHz, and in terms of performance, standard voltage CPUs are a notch higher than low-voltage CPUs.

CPU overclocking is a method of increasing the frequency speed of an electronic component to operate at a speed higher than the manufacturer's limit, thereby improving performance, but this may lead to a decrease in the stability of the accessory.

Overclocking activities are popular among PC enthusiasts to get the most out of their computers.
