What is the difference between laptop CPU low voltage and standard pressure?

Many people in the process of using a notebook, often pay attention to their CPU performance, we will see the notebook CPU model behind the usual "U", "M" and other words, and "u" is the meaning of low pressure, "M" is the meaning of the standard pressure. Recently, a lot of net users of notebook CPU low-voltage and high-pressure difference is not very understanding, so do not know in the purchase of the notebook when the voltage suitable for their needs. For everyone to ask more, the following small series for everyone detailed notebook CPU low-voltage and notebook CPU high pressure difference between.

Notebook CPU in English called Mobile CPU (moving CPU), it in addition to the pursuit of performance, but also the pursuit of low heat and low power consumption, the earliest laptop computer directly using the CPU, but with the increase in CPU frequency, notebook computer narrow space can not quickly emit the heat generated by the CPU, Laptop batteries are also unable to afford the huge power consumption of desktop CPUs, so the mobile CPU, designed specifically for laptops, is often made more advanced than the desktop CPUs of the same era, because the mobile CPU integrates the technology of the computer that is not available in the desktop CPU, And the higher micron precision will be used first. The main manufacturers have Intel, AMD, the United States and so on.

There are many metrics for measuring the CPU performance of notebooks, these include frequency, FSB, frequency multiplier, front bus (FSB) frequency, CPU bit and word length, caching, CPU extension instruction set and CPU kernel and I/O work voltage, which is why the notebook CPU has low voltage and pressure and high pressure address.

　　I. Low-voltage CPU for users who do not pursue high performance

Notebook CPU Low pressure TDP (thermal design power consumption) is less than 14W, generally speaking, low voltage version of the CPU performance is low, but the endurance is good, for example, low-voltage version of the i5 processor and the standard version of the i3 processor performance is comparable. At present, many ultra-extreme in the market is the use of Low-voltage version of the CPU, its advantages are small size, light weight, compared to save electricity, longer duration. The disadvantage is that performance is weaker. For those who like to play large network game box professional design, the Low-voltage version of the CPU will not be considered. In short, low-voltage CPU notebook is very cheap, for those who do not want to spend more money can choose to buy Low-voltage CPU notebook.

Note: The notebook CPU model with the words "U" is a low-voltage version of the CPU.

The following is a small series of low-voltage version of the CPU model, for your reference.

Intel processor Core I3:4100U/4158U/4010U/3217U

Intel processor Core I5:4210U/4250U/4350U/4288U

Intel processor Core I7:4510U/4650U/4550U/4558U

　　Second, for those who do not pursue the ability to choose the standard pressure CPU

Notebook CPU pressure of TDP (thermal design power consumption) between 35w-45w, generally speaking, the standard version of the CPU performance than Low-voltage version of the CPU performance is much better, but the duration is relatively short. For the pursuit of better performance of the user, the minimum requirement is to buy the standard pressure CPU, the advantage is that performance. If you do not consider the laptop's endurance, it is recommended to buy a normal voltage processor.

Note: The notebook CPU model with the words "M" is the standard pressure version of the CPU.

The following is a small collation of the standard version of the CPU model for your reference.

Intel processor Core I3:2350M/380M/3110M/2310M/2330M

Intel processor Core I5:3210M/480M/2450M/430M

Intel processor Core I7:620M/2620M/2640M/640M

PostScript: Notebook CPU Power consumption affects the performance of the CPU, CPU low voltage and CPU standard pressure represents a different performance. Users can follow their actual use and needs to choose a different power consumption of the notebook CPU, for the public users, the choice of the most or the standard version of the CPU notebook.
