One, come
Although I have been studying computers for a while, some hardware has always been a blind spot. In the free time in the future, I will slowly learn about the query information.
This article will take my computer as an example, and firstly introduce the problem about CPU.
Second, introduce the CPU
CPU (central processing unit) is the central processing unit, which is equivalent to the small head of the computer. Judge whether potatoes are expensive for 1 yuan and 3 pounds? Is 5 cents worth of biscuits worth? It's up to him.
Now the famous central processing unit (CPU) manufacturers are mainly Intel and AMD, but Intel alone accounts for about 80% of the global market share.

Intel® Core™ i7-7700HQ CPU @2.80GHz
On the small piece of paper next to the keyboard of the computer, this is also
What does Intel® Core™ i7-7700HQ CPU @2.80GHz mean?
The following is a step-by-step explanation
1. What is Intel® Corei7?
Intel, the manufacturer is Intel, is a company in the United States that mainly develops CPU processors, and is the world's largest manufacturer of personal computer parts and CPUs.
Core i7, Chinese: Core i7 , the processor is a 64-bit quad-core CPU launched by Intel in 2008, the name of Core i7 has no special meaning, Intel said that the reason for taking the name i7 is just to sound pleasant, 'i' and '7' has no special meaning, let alone the 7th generation product. The Core is a continuation of the success of the previous generation of Core processors, and programmers with sentiment are willing to call it "the beloved wife" .
In addition, i and the numbers after it are fixed collocations, just a name.
i3 is a mid-range processor, i5 is a mid-to-high-end processor, and i7 is a high-end processor.
The three-digit number that follows is the first generation, the four-digit number starting with 2 is the second generation, the four-digit number starting with 3 is the third generation, and the four-digit number starting with 4 is the fourth generation.
which is:
The first generation is i3/i5/i7xxx (three digits)
The second generation is i3/i5/i72xxx (four digits, starting with 2)
The third generation is i3/i5/i73xxx (four digits, starting with 3)
The fourth generation is i3/i5/i74xxx (four digits, starting with 4)
2. What does 7700HQ mean?
The first number in the four-digit sequence represents the generation number of the processor, and the next three digits are the SKU number (SKU: abbreviation of Stock Keeping Unit, meaning such as inventory number, which generally refers to the manufacturer's own product. Numbering.). The processor name has a letter suffix at the end that represents the processor family .
For the series number of the Core 7th generation processor, H stands for high voltage, which is welded and cannot be disassembled, and Q stands for high performance level . Therefore, HQ is a high-voltage high-performance processor.
Nowadays, the replacement is faster, and the naming method may also change, but understanding some basic rules of naming will help you when choosing a computer to choose a model.
Below is a table for quick query.
3. What does 2.80GHz mean?
This refers to the main frequency of the CPU, 2.8 is the number, and ghz is the frequency unit. The higher the frequency, the faster the speed. The main frequency is related to the actual operation speed, but it can only be said that the main frequency is only one aspect of the performance of the CPU, not the overall performance of the CPU .
To sum up, the configuration of my computer's CPU is simply a mid-to-high-end notebook processor with a quad-core and eight-thread processor with a main frequency of 2.8GHz. Because it is a high-voltage, welded CPU, it cannot be disassembled. .
The CPU12 generation was just put on the shelves two days ago. It is said that it can be done in seconds , but the real situation is unknown, and I have not experienced it myself. Interested friends can go to the evaluation. It is said that the price is suitable.
The iterative process of the CPU can be seen from the ladder diagram below.
CPU ladder diagram, from the Internet.
3. End
In fact, I have always been a computer novice, but when I entered this major, I had to ponder and try and make mistakes.
