NVME paper
It's like a car giving you ten tires, okay? \x0d\ Nowadays, mobile phones rely on auditing to make a selling point, which is a bit deceptive. \x0d\ Actually, ten cores refer to the CPU inside the mobile phone. Now the CPU of the mobile phone has two cores, four cores and ten cores. \x0d\ But the more cores, the better. It depends on process technology, leakage rate, scheduling mechanism, calorific value, system optimization, CPU structure and other comprehensive factors. \x0d\ There is no doubt that Apple has done the best in this respect. In the IPHONE6 era, according to the actual measurement of many websites, Apple's A9 dual-core can greatly surpass many Snapdragon quad-core CPUs in Android (actually last year or so), and Snapdragon can surpass 10 core (10 core generally uses MediaTek's CPU)\x0d\ and Apple can surpass it only by dual-core. \x0d\ Every link of Apple products is like every piece of a puzzle, which can be well butted together to form a beautiful picture. In human terms, Apple's IOS system is optimized for the system, and the CPU can be designed for the actual needs of the system because it is only used by Apple itself. NVME is used in storage, which is interlocking. \ x0d \ Android platform needs to consider universality, and Android system needs to make one system correspond to n CPUs, and each Android system has been optimized by various so-called optimizations of major manufacturers. If the above picture is used as an analogy, it is not like a jigsaw puzzle, but some irregular figures are spliced together in an attempt to become a complete figure, and many places have to make compromises in order to maintain universality. It is impossible for CPU manufacturers to make targeted CPU for a mobile phone manufacturer's system, and a mobile phone manufacturer can only make limited changes to the system on the basis of Android system, and the above applications have also made some compromises in order to consider universality, so it is difficult to achieve complementary situations, so quad-core can't beat Apple's dual-core. \ x0d \ x0d \ and 10 core is not high enough. The main reason is that there are still some design problems in the architecture. For example, the area of mobile phone chips is so large that the manufacturing process (simply understood as the smallest area that the core can achieve at present) is similar. To make 10 kernel in a limited area, the first consideration is to avoid heating. Because the area is almost the same, the increase in the number of nuclei will inevitably lead to. And speaking of this, the so-called 10 mobile phone core does not work at the same time, and it will call different core groups with three different strengths: high, medium and low. For example, the game will call the quad-core with relatively high frequency, and ordinary quad-core with medium frequency such as Weibo Post Bar. Some systems, such as computers or standby, use two cores with low energy consumption (that is, the lowest frequency). Because the frequency of each core group is different, it is impossible to do the same thing at the same time. . . . Moreover, the problem of fever should be considered, so sometimes 10 core is not necessarily stronger than quad core or even worse than quad core. Anyway, the problems involved are very complicated, so you can write a paper. . . . \ x0d \ x0d \ So what Apple wants is the best performance and system, followed by Snapdragon CPU camp, and finally MediaTek CPU camp. . .
