This article mainly introduces the computer cpu main frequency is not the higher the better related knowledge, the content is detailed and easy to understand, simple and fast operation, has a certain reference value, I believe that after reading this computer cpu main frequency is not the higher the better the article will have a harvest, let's take a look.

What is the main frequency of cpu?

Cpu main frequency, that is, the clock rate at which the cpu kernel works (CPU Clock Speed). The commonly seen cpu parameters 2.5GHz, 3.4GHz and so on refer to the CPU main frequency. As an important parameter of cpu performance, cpu main frequency is not directly related to the operation speed, but it is very important to improve the operation speed.

Is the higher the main frequency of cpu, the better?

In an absolute environment (excluding the influence of external hardware), the higher the main frequency of the same series of cpu, the faster the processing speed of the computer or mobile phone. For example, 2GHz main frequency cpu processing speed is twice as fast as 1GHz main frequency cpu. The intuitive feeling is that the system runs faster and the game loading speed is faster. The higher the frequency of a single cpu, the better does it mean better performance?

What are the factors that affect CPU performance?

In fact, to judge the performance of a cpu, you need to look at not only the main frequency of cpu, but also the core of cpu, the number of threads and cache capacity.

The core, also known as the kernel, is commonly referred to as "how many cores" and is the most important part of cpu. All cpu calculations, receiving / storing commands, and processing data are performed by the core. In the case of the same brand and all cores work, the more the number of cores, the faster the processing speed (the same brand is emphasized here because due to different processes, sometimes AMD8 cores are not as good as Intel4 cores).

Thread refers to the ability of cpu to process tasks at the same time. Usually, the number of threads corresponds to the number of cpu cores, and there are as many threads as there are cores. Intel's hyper-threading technology simulates two logic cores into two physical hyper-threading chips through special instructions, and implements double threads on one core, making full use of cpu idle resources to improve performance. What should be careful here is that some businesses will use computer system display problems to deceive consumers with dual-core 4-thread U as 4-core, so it is best to use software to identify them when choosing and buying.

Caching is a component used to reduce the average time it takes for a processor to access memory, which has a significant impact on cpu performance. Generally, the cache capacity is smaller than memory, but faster than memory. Cpu first retrieves or reads data in the cache, so the capacity and quantity of the cache are directly related to the speed. At present, the processor cache has first-level cache, second-level cache and third-level cache. The larger the cache capacity and the more cache levels, the faster the cpu processing speed. In addition, the performance of cpu will also be affected by architecture, process and other hard parts.

This is the end of the article on "is the computer cpu main frequency as high as possible"? thank you for reading!
