What does PC 4500U mean, and what does Core i7 4500U mean

4500U, estimated to be the CPU of the computer, i7 4500U. If you are buying this computer, it is recommended to also consider, the main reason is that the CPU with the computer in the U is a low-voltage product. The power consumption is very low, and it is generally used on the superbook.,The performance is very average.,If you buy it mainly for playing games or making pictures,You need to be cautious。

U after the CPU model number

It represents the low-voltage version.

M behind the CPU model

The standard voltage version is represented.

Performance-wise.

Core i7 4500U, which means that in the computer configuration, the processor performance of the computer is good, and the processor of the i7 4500 model is used.

That's what it means, nothing else. This kind of CPU with Jingying GTX1060 6G graphics card, you can play chicken games smoothly.

This is this CPU, which is the 4th generation of the Core i7, and then it is the low-voltage U. That is to say, this CPU has compression compared to the standard version.

A low-voltage version of the CPU for notebooks

The i7 type of prefix is a big category that goes something like this:

i3 General Household & Commercial.

i5 General Games & General Design.

i7 Enthusiast Player Level.

The suffix is a different model, and the number indicates some parameters, that is, some specific main frequency and other data under the general category.

The letters that follow it indicate some positioning:

k: Unlocked frequency multiplier (can be overclocked).

Q: The quad (4 groups) is the 4 cores.

m: Mobile is used for mobile terminals (laptops).

e: Embedded (embedded) is used for embedded systems, simply put, it is used for industrial control.

ES: Abbreviation for Engineer Sample. The ES version generally refers to the version where the ES is not visible, and generally refers to all the samples of the beta version.

ES version usually we are talking about the CPU version that can not display the model, the stability of this type of CPU is uncertain, depending on the different steps to judge its stability and whether there is a defect, the closer the step is to the official version, the smaller the risk, with the characteristics of being particularly cheap, when it is closer to the official version, its stability is generally more stable, it is one of the cheapest options, and it is also one of the versions used by barebones merchants.

QS: Abbreviation for English qualification sample. The QS version, also known as the ES positive version, is generally the last version of ES.

Generally, its steps and models,Are exactly the same as the official version,Its stability does not have any risk,Among all the beta versions,It is the best version,Its source is not free like ES**,Intel charges a small fee to the factory to sell,**Still much lower than the official version,Stability is the same as the official version in all aspects,For those who do not want to take a little risk,And the pursuit of cost performance,It is the best choice。

u: Ultra processors, that is, ultra-low voltage processors, although low voltage processors have many advantages in terms of power consumption, battery life, and heat, but due to their voltage limitations, the main frequency of ultra-low voltage processors is generally low, which directly affects the computing power of the processor. The performance of ultra-low voltage processors is basically one level different from that of standard voltage processors.

That is, the third generation of low voltage i7 is equivalent to the third generation of standard voltage i5. Generally only found on ultrabooks. The U-series also has the feature that it is BGA packaged, which is soldered to the motherboard and cannot be upgraded.
