What is the difference between four and eight-core mobile processor? Little difference in performance

　Undoubtedly, the central processor (CPU) is the brain of all the computer equipment, smart phones as well. With the development of technology based on ARM core mobile processor also received a great upgrade from breakthrough clocked at 1GHz, dual-core, quad-core to the current eight-core, there seems Competition desktop processors posture. 

　　Of course, different architecture, performance is different, most consumers are able to understand even quad-core mobile phone and PC processor is actually completely different. So back to the mobile space, the phone's eight-core processor is a quad-core processor has twice the performance? 

　　difference quad-core and eight-core

　　In simple terms, a quad-core processor is that it has four processing cores, can work together.Eight-core part is divided into two types, one is actually a "dual quad-core", that there are eight core, but can not work together, which is often used in the four core communications infrastructure and other parts; the so-called "true eight-core "it is theoretically possible to open eight cores simultaneously, collaborate processing. 

　　From core architecture, the quad-core and eight-core processors are based on ARM, which includes true eight-core processor Qualcomm Snapdragon 810, Samsung Exynos 5433, Nvidia Tegra X1 and so on. Of course, some of the details are slightly different from each vendor. 

　　Little difference in performance

　　According to the results Geekbench 3 other specialized software to run sub-tests showed that eight-core processor, a higher score indeed, in theory, performance is stronger. However, for mobile phones, tablets and other mobile devices, really need to weigh the balance between performance and battery life, so in practical applications, users may not feel a huge difference.Another classic case is Apple iOS device has a dual-core processor, but optimized iOS itself is excellent, so from the actual operating speed, performance and other aspects of the game, it seems that is not inferior to eight-core processor, equipped with Android phones. 

　　Summary

　　For now, using the eight-core processors and quad-core processor Android phones in terms of performance, and not a huge difference, at least twice the upgrade can not be achieved. But clearly, the processor and the mobile phone manufacturers either from its own technical development or marketing, you need to constantly improve our product, just a few years ago, we questioned whether it was necessary quad-core processor for mobile phones, but now almost universal. Meanwhile, due to the movement of the system is 64, for treatment, integrated graphics chips are increasingly high, eight-core processors will also be a trend. Of course, we want to see is a balance of performance and power consumption, after endurance for smart phones is the most important.
