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

All brand notebooks in the 2014 are mostly in the direction of light and light, and many lightweight laptops often carry low voltage processors, and the game is often equipped with standard voltage processors. Although the same as the I3/i5/i7 series processor, but the same specifications of low-voltage and standard voltage notebook in terms of performance and price will also be different. What exactly is a low voltage processor? What is the difference between low voltage of notebook CPU and standard computer? This article will be detailed introduction to the user.

　　One, what is low voltage processor

Ultra-low voltage processor, the English full name "Ultra High Voltage" also known as the ULV processor, its end name usually with a U end, such as I5-4200U. The current low voltage processor mainly has T series, U series, y series. The U series is usually a notebook low voltage processor, with both performance and low power consumption, while the standard voltage is M end; The T-series is a low-power processor for desktop desktops, while the Y-series is the lowest of Intel's power consumption, such as the Microsoft Surface Pro 3 tablet, Acer P3, which uses the Y-series Low-power processor.

Low-voltage, lightweight, stylish notebook appearance

Low-voltage processors tend to mean low-power, such as the four-generation U-series Low-voltage processors, which have a power dissipation of only 15W or 28W, while the Y-series power consumption is only 7W, while the desktop T-series processor is 45W, and the power consumption generally reaches 84W compared to the desktop standard voltage i5 processor.

　　Two, notebook CPU standard voltage and voltage difference

The standard voltage and low voltage notebook CPU mainly has the following several differences:

　　1, naming different

Low notebook CPU its name often followed by a U end, such as I5-4200U, while the standard voltage notebook CPU its end name usually has an M end, such as i5-3230m.

　　2. Different power consumption

U series Low-power notebook processors typically consume at 15W or 28W, while standard voltage notebook processors typically consume less than 35W or higher, and low-power CPUs can lead to longer endurance.

　　3, different performance

Low power notebook processor frequency is often less than 2Ghz, and standard voltage processor frequency is usually above 2Ghz, in terms of performance, standard voltage CPU than low voltage CPU performance to a higher grade.

For example, the low voltage notebook processor I5-4200U performance is basically equivalent to the four-generation standard voltage I3-3210MI processor performance, performance is basically to reduce a grade.

　　Third, notebook CPU standard voltage and low voltage which is good?

For the processor quasi-voltage and low voltage which is good, in fact, there is no absolute answer, if pay attention to performance, the standard voltage notebook CPU is certainly more recommended, but low voltage notebook CPU is usually used in the light and fashion notebook, such notebooks with lightweight and portable, attractive appearance features, So about the laptop CPU standard voltage and low voltage which is good, mainly according to the use, the CPU is not now notebook bottleneck, Low-voltage i5 processor can also meet office, audio-visual entertainment and most general network games, pay attention to the appearance of the user is usually worth considering; if it is playing a large game, the performance requirements , the first of course is the standard voltage CPU.
