Ultra-low voltage processors, also known as ULV processors, usually end with U, such as i5-4200U. The current low-voltage processors mainly include T series, U series, and Y series. The U series is usually a notebook low-voltage processor that takes into account both performance and low power consumption. The standard voltage ends with M; the T series is a low-power processor for desktop computers; and the Y series is Intel’s lowest power consumption series. For example, Microsoft Surface Pro 3 tablet and Acer P3 use Y-series low-power processors.
Low-voltage processors often mean low power consumption. For example, the fourth-generation U-series low-voltage processors generally consume only 15W or 28W, while the Y-series power consumption is as low as 7W, while the desktop T-series processors are 45W. Compared with the standard voltage i5 processor of a desktop computer, the power consumption generally reaches 84W.
The main differences between standard voltage and low voltage notebook CPUs are as follows:
1. Different names
Low notebook CPUs often end in U, such as i5-4200U, while standard voltage notebook CPUs usually end in M, such as i5-3230M.
2. Different power consumption
U-series low-power notebook processors usually consume 15W or 28W, while standard-voltage notebook processors usually consume 35W or higher. Low-power CPUs can bring longer battery life.
3. Different performance
Low-power notebook processors often have a clock speed of less than 2Ghz, while standard voltage processors are usually above 2Ghz. In terms of performance, standard voltage CPUs have a higher performance 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 grade.
There is no absolute answer as to whether the processor quasi-voltage or low-voltage is better. If you focus on performance, standard-voltage notebook CPUs are definitely more recommended. However, low-voltage notebook CPUs are usually used in thin and stylish notebooks, which are thin and portable. , The appearance is beautiful, so regarding the notebook CPU standard voltage or low voltage which is better, mainly according to the purpose, the CPU is not the bottleneck of the notebook nowadays, the low voltage i5 processor can also meet the office, audio and video entertainment and most general online games. The appearance of the user is usually worth considering; if you are playing a large game and have higher performance requirements, the first of course is a standard voltage CPU.
1. Long battery life brought by power saving. Take the Core Duo platform product as an example. The TDP of the conventional version is 31W, and the TDP of the ultra-low voltage version is reduced to 9W, which is less than one-third of the conventional version and more than 1W. The TDP of the single-core Core Solo has reached 5.5. The ultra-low level of W.
2. The ultra-low-voltage processor models released in the past two years are equipped with Intel Digital Media Acceleration-a new micro-architecture improved design, including instruction optimization and performance enhancement, which can speed up the processing speed of various intensive computing tasks.
3. The low price makes the cost and price of ultra-thin notebooks drop.
With the development of technology, the functions of processors are becoming more and more powerful, and people have higher and higher requirements for the thinness and battery life of notebooks. Ultra-low voltage processors will definitely be used more and more widely.
