What are the main parameters of CPU? What are the common CPU models?

At present, most of the common computers are Intel Core i3 series i5 series i7 series CPUs, AMD Phenol, Athlon, Ryzen CPUs, etc. There are many models for each series.

Most of the mobile phones are CPUs such as Qualcomm Snapdragon, HiSilicon Kirin, Apple, and MediaTek Dimensity series.

1.First, let's take a look at the model types of CPUs. One is Intel's Core i3, i5, i7, i9 series, and the other is AMD Ryzen R3, R5, R7, R9 series.

Let's start with Intel's CPU. The common standard CPUs nowadays are the quad-core i5-10200H and i5-11300H. Hexacore i5-10500h,i7-10750h;; Octa-core i7-10870H, i7-10875H, i9-10980HK.

Common low-voltage CPUs are i7-1165g7, i5-1135g7, i5-1130g7, i7-1065g7, i5-1035g4, i5-1035g1, i5-10210u, all of which are quad-core and often used in thin and light notebooks.

2.Here, too, Intel's engineers distinguish between different levels of performance. i3 represents the low end; Say i5 mid-range series; The i7 and i9 represent the high-end range.

Take i5-10200H as an example, where "10" represents the 10th generation, the following "200" represents specific specifications such as core frequency architecture, and "H" represents standard voltage. If "HK" indicates the standard voltage overclocked version, "U" indicates low voltage. The "G7, G4, G1" suffix indicates low voltages with different core display (integrated display) performance.

1.Main frequency: It is obtained by multiplying the external frequency and the frequency doubling (generally the CPU external frequency is about 133MHz to 300, and the octave is about 30-40 from 5 to very high).

2.Number of cores: There are several cores.

3.Number of threads: The source is simply understood as how many operations can be processed at the same time, generally a few cores and a few threads, Intel's HT hyper-threading technology can be a dual-core hail lead CPU with 4 threads, this technology is used on the original P4 and the current I series processors.

4.Manufacturing process (process): refers to the connection distance between transistors, the smaller the more power-saving, the better, generally there are so many 90nm (almost extinct), 65nm (dual-core mainstream), 45nm (4-core mainstream), 32nm (latest, 6-core mainstream).

When buying a computer, the most important reference standard is the various parameters of the CPU, here are the main parameters of the CPU?

Frequency. The main frequency is the clock frequency, which is used to represent the operation of the CPU and the speed of processing data.

External frequency. The external frequency is the base frequency of the CPU, which determines the speed of the entire motherboard. In desktops, the so-called overclocking is the external frequency of the super CPU (in general, the frequency doubling of the CPU is locked).

However, the server is not allowed to overclock, if the server is overclocked and the external frequency is changed, asynchronous operation will occur, resulting in the instability of the entire server system.

Frequency multiplication. Frequency doubling refers to the proportional relationship between the CPU main frequency and the external frequency. At the same external frequency, the higher the multiplier, the higher the CPU frequency.

The front-side bus frequency is the bus that connects the CPU to the Northbridge chip. When buying a motherboard and CPU, pay attention to the matching of the two.

CPU cache, cache refers to the high-speed data exchange can be carried out in the virtual area, the structure and size of the cache has a great impact on the CPU speed.

CPU encapsulation technology. The packaging of the CPU is also very important to the chip, because the chip must be isolated from the outside world, and the impurities in the air will corrode the chip circuit and cause the electrical discremation performance to deteriorate.
