Choose a suitable industrial panel PC CPU configuration
Many buyers of industrial tablet computers do not know how to choose a CPU. In fact, there are only a few main parameters of the processor. As long as you master a simple rule, you can easily and arbitrarily choose a processor product. The CPUs on the market are mainly Intel and AMD. First of all, when we choose a CPU, we must first look at its architecture. The so-called architecture is a specification set by the CPU manufacturer for CPU products belonging to the same series. A simple understanding is that each generation of products The architecture is different. The newer the architecture, the better it will be. For example, Core is better than Pentium, and Pentium is better than Pentium.
CUP: Here is the meaning of the numbers and letters of Intel's fourth-generation Core processors (the first three generations of letters and numbers have similar meanings): One "4": represents the fourth generation of Intel Core processors; the second " 5", "6", "7", "8", and "9": represent the processor, etc., the higher the number, the higher the performance; the third bit "3" "5" "0": this bit is basically the corresponding core The model of the graphics card, where "3" represents a high-performance processor with HDi4600; "5" represents an Iris 5000, 5100 or Pro5200 for the core graphics card; and "0" is an HD 4600; the fourth digits "0" and "2" ""8": "0" represents 47W in standard voltage and 15W in low voltage; "2" represents 37W, "8" represents 28W in low voltage processor; the fifth digit "MX"" HQ""MQ""U": "MX" stands for flagship, "HQ" supports vPro technology, "MQ" version does not support, "U" stands for ultra-low voltage mainly 15W and 28; the fifth "MX"" HQ" "MQ" "U": "MX" stands for flagship, "HQ" supports vPro technology, "MQ" version does not support, "U" stands for ultra-low voltage, mainly 15W and 28;
Main frequency: The higher the main frequency, the faster the change frequency of the internal clock of the CPU, so the CPU can complete more operations (instructions) in a shorter time, so the operation speed of the CPU will be faster. But boosting the main frequency is also a bottleneck and a costly way. First of all, the heat is positively related to the main frequency in theory. After the main frequency increases, the heat increases exponentially, so the problem of heat dissipation if the main frequency is too high. Secondly, after the main frequency is too high, other mechanisms in the CPU will become bottlenecks, resulting in unsatisfactory CPU performance improvement under ultra-high main frequency.
Number of cores: Of course, the more cores, the better, but the issue of power consumption and heat generation should be considered. The larger the number of cores, the greater the heat generation and power consumption. Simply put, the CPU is like the engine of a car, a single-core is one engine, a dual-core is two engines, and so on, of course, the larger the number of cores, the better the experience in actual use, especially now the game. The optimization of multi-core CPUs in the design is not good enough, so when using industrial tablet computers, only one CPU is fully used, and other cores are idle, so the use of industrial tablet computers is still Intel's CPU, because Intel's single-core performance Stronger than AMD, but much more expensive.
Number of threads: The number of threads will affect the download speed. But it is not that the more threads, the better. Assuming that data is transmitted from the server to the client, the client and the server are compared to two islands, and the number of threads is compared to a bridge connecting the two islands, and the more bridges are built. , the more data is transmitted per unit time, but if the bridge erection exceeds the number that both parties can bear, the client will not be able to accept data from other servers, and the server will not be able to transmit data for other clients. Therefore, the number of threads How much depends on the specific situation of the server and the user.
Cache: Cache is a temporary storage located between the CPU and memory. Its capacity is much smaller than that of memory, but the exchange speed is much faster than that of memory. The appearance of the cache is mainly to solve the contradiction between the CPU operation speed and the memory read and write speed, because the CPU operation speed is much faster than the memory read and write speed, which will make the CPU spend a long time waiting for the data to arrive or write the data. RAM. The data in the cache is a small part of the memory, but this small part is about to be accessed by the CPU in a short time. When the CPU calls a large amount of data, it can be called in the cache first, thereby speeding up the reading speed. Generally speaking, the bigger the second cache, the better, which is why the CPU frequency of Celeron series is relatively high, but it is not as good as the Pentium series in actual application, but the second cache is very important for Intel products, but the second cache It's not as important for AMD as it is for Intel, because AMD has triple cache in addition to the second cache.
At present, as far as industrial applications are concerned, the CPUs of industrial tablets are generally about 2-3 years behind commercial electronic products, so you can see what the best CPUs were 2-3 years ago, and not only CPUs at the same time. Yes, what's the difference between the two? Therefore, choosing an industrial tablet is a whole and should be considered in many aspects. The CPU is just a code name and has no practical significance. Just look at the CPU frequency and bus specifications and technology, such as functions, configurations, modules, etc. Higole industrial tablet computer CPU is the main Celeron J3355, N4120, N3450, etc. in the Windows system, and the Android system is mainly the domestic chip RK3399, RK3288, RK3566 and so on.
