The processor frequency is an important parameter of the CPU, which affects the performance of a processor. Many people will choose to buy accessories online, and it will be more cost-effective to install them themselves. If when buying a CPU, the seller desperately tells you that the higher the CPU frequency, the better. You must be careful not to get scammed. In addition to the cpu processing frequency, there are other parameters. Just like cooking, the more salt, the better? Let's take a look at the information and then make an evaluation.
CPU frequency is the clock frequency of the CPU cores and is also the computer processing speed. Usually, when buying a CPU, merchants will put some 2.5 GHz and 3.4 GHz parameters prominently.
As an important parameter of CPU performance. In the absolute environment, the higher the CPU frequency of the same series means the faster processing speed and stronger performance. For example, 2Ghz processes twice as fast as 1Ghz. But is higher CPU frequency better?
In order to judge the performance of the CPU, in addition to the CPU frequency, it is also necessary to look at the cores, number of threads and cache capacity of the CPU. The core is the most important part of the CPU. In the same production process of the same brand, the more cores, the faster the processing. Threading refers to the ability of the CPU to process tasks simultaneously. It should be noted that some merchants will use the problems displayed by the computer system to treat the dual core 4 thread U as 4 cores to attract and deceive consumers. The cache is a component used to reduce the average time it takes for a processor to access memory, which has a large impact on CPU performance.
The higher the CPU frequency, the stronger the performance. This is based on the same-generation architecture, the number of cores/threads, the manufacturing process, the cache, etc. When choosing a CPU, you also need to look at the architecture, the number of cores/threads, and the manufacturing process. , cache and other core parameters.
The higher the CPU frequency, the better the performance of the computer, which should pay attention to other collocations.
With the increase of the CPU frequency, its heat will inevitably increase along with it. The consequence is that the notebook will become hot during use. Too much heat will cause the system to become unstable and crash.
How fast a processor you need depends on how you plan to use your PC. Most computers can meet the daily needs of users. For example, the N3350 processor, the main frequency of 1.1GHz can meet the daily needs of browsing the web, watching movies, processing word files, etc., but if you want to use resource-intensive programs, such as large-scale games, graphics, etc., you need a better processor . Such as I5 I7 9th generation and later processors, their main frequency is usually between 2.3 and 4.8GHz,which is also the current mainstream processor frequency for gaming laptop.
At the end of 2021, Intel's best mobile processor for laptop is the I7-11800H, with a base frequency of 2.3GHz, a turbo frequency of 4.6GHz, 8 cores and 16 threads, and a 24M cache.
CPU external frequency or base frequency, measured in "MHz". The main frequency of the CPU and the FSB have a certain ratio (multiplier) relationship. Since the operating frequency of the memory and the L2Cache set on the motherboard is synchronized with the CPU FSB, the overall performance of the computer using a CPU with a high FSB is better than using The CPU with the same main frequency but one level lower FSB should be higher. This parameter relationship is used for the selection of the motherboard.
The proportional relationship between CPU main frequency and FSB is generally: main frequency = FSB * multiplier. If the heat dissipation of the notebook is not done well, it may also cause the components of the notebook to burn out, especially for those users who like to put the notebook on the bed and use it, a suitable motherboard can be more conducive to the performance of the graphics card and CPU.
In the same series of microprocessors, the higher the main frequency, the faster the computer, but for different types of processors. It can only be used as a parameter for reference. In addition, the operation speed of the CPU depends on the performance indicators of various aspects of the CPU pipeline. Because the main frequency does not directly represent the operation speed.
Therefore, under certain circumstances, it is very likely that the actual operation speed of the CPU with higher main frequency will be lower. Therefore, the main frequency is only one aspect of the performance of the CPU, and does not represent the overall performance of the CPU.
The newly bought brand laptop has a slow and laggy response card, what is the cause and how to fix it? The possible reasons and fixes are as follows:
Develop good computer operating habits, do not run multiple large software at the same time, close unnecessary programs and windows in time, and clean up memory in time.
If your laptop starts slowly, the most likely cause is the hard drive and the system. The speed of solid-state drives is many times higher than that of mechanical hard drives. If your computer is an old-fashioned mechanical hard drive, you can replace it with a solid-state drive. If your computer is Windows 7 or older, it is recommended to replace it with Windows 10 if the computer hardware supports it, and the startup speed will be 30-40 seconds faster.
The refurbished laptop and the new laptop actually look the same on the surface, but there is a big difference in use. So how do we distinguish these laptops with the same surface? For people who understand, a little careful observation can tell the difference between true and fake.
what is a refurbished laptop? The shells generally used in refurbished machines are imitated original ones, or the old shells are carefully processed, so the front and rear parts of the machine shell are prone to not close tightly and have large seams. The identification method is to carefully observe the front and rear shells. Whether there is a warped or open seam at the seam.
Use the cmd command "systeminfo", this command is used to display detailed configuration information about the computer and its operating system, including operating system configuration, security information, product ID and hardware properties such as memory, disk space, network card and patch information, etc.
Shortcut key Win+R, enter cmd and press Enter, enter systeminfo.
should i buy a refurbished laptop? Whether or not a refurbished laptop is worth buying is largely up to the buyer. Some people are more taboo about second-hand products or are afraid of frequent problems with laptops, so they choose to buy brand new laptops. Others, due to financial reasons or wanting to buy high-performance laptops at low prices, also try to buy refurbished laptops. The advantages and disadvantages of refurbished notebook computers are listed below for your reference.
The dimensions of a 14-inch laptop refer to a screen that is 14 inches diagonally, which is 35.56cm diagonally. If you know the aspect ratio of the screen, you can calculate it. You need to add 0.5cm to 2cm outside the screen. Taking a 16:9 laptop as an example, a 14-inch narrow bezel laptop is 32cm long and 18.4cm wide, and the screen is 31cm long and 17.4cm wide.
Whether a 14-inch laptop screen is big enough depends on your purpose. For ordinary business notebooks, 14 and 15.6 inches are the most popular screen sizes, because business notebooks mainly consider certain performance and portability. If you buy an electric laptop for general work, such as doing PPT, word documents, etc., then 14 inches is enough. If you're buying a laptop primarily for gaming or CAD drawing, etc., a 14-inch laptop is too small for you. then a laptop between 15.6 and 17.3 inches will be more suitable for you, but they will be more expensive and heavier. If you want a laptop with high performance and portability, it is a better choice to choose a 15.6-inch laptop as a compromise.
