Everyone knows that the CPU is the brain of the computer and is a very important part of the computer. Therefore, when purchasing, you must choose a high-quality CPU, but many computer whites are recommended by the manufacturerâ€™s brother, you must know people. It is necessary to maximize the benefits, and the price/performance ratio that is not necessarily recommended to you is the highest.Â The following small series takes everyone to understand the situation that CPU purchase should pay attention to.
1, i7 must be better than i5: Some friends may say, of course, buy a computer to buy i7 or more, because the performance of i7 is definitely better than i5 and i3.Â So i7 must be better than i5, obviously not so simple.Â The so-called i5, i7 are just a rough classification of Intel’s CPU models, they do not represent the absolute ranking of processor performance.Â Because Intel’s processors are divided into multiple series for different devices, the performance and power consumption differences between different series are huge.Â If it is the same generation of products, i7 will generally be better than i5 and i3, then what is the same generation?Â For example, the i7-8700 CPU and i5-8500, the first digit of the last four digits, represents the first generation of CPU, these two are the same generation, so the natural i7-8700 is stronger than the i5-8500.
2, the more the number of cores, the better? When you buy a computer, the general sales staff will say that our CPU is a few core cores, although the core number is an important reference for the CPU, but the core number does not necessarily represent all.Â For a CPU, whether to support Hyper-Threading Technology, default frequency, maximum core frequency, whether to support overclocking and other parameters are very important reference content.Â Therefore, in the process of purchasing a processor, it is unscientific to judge the quality of a CPU only by the number of cores.Â It should be noted that due to the different architectures of the products, Intel and AMD are different for the processor’s main frequency standard and cannot be directly used for horizontal comparison.
