Smartphone Selection Guide-Revealing the Real Performance of High-Frequency Smartphones

Information

 Abstract: Hisilicon K3 Hi3611 processor is equipped with full hardware video codec, graphics acceleration, and hardware ASP. The processor core is similar to the multi-core design concept of PC. The actual computing power of K3 processor is 4-6 for other platforms. Times. It should be said that K3 is no longer a CPU, but a single chip micro PC (PC on a Chip) with a CPU, graphics card and sound card.

       Once upon a time, when people chose mobile phones, they began to pay more and more attention to the main frequency of the processor, 300MHz, 400MHz, or 600MHz? There is a tendency to set the performance to the price with the main frequency. It is true that the performance of a smartphone is determined by the performance of the processor used, but users of multiple smartphones may feel that the CPU frequency of a smartphone is higher and higher, but it is not really used. I feel that there has been any substantial improvement in the speed of the machine, even a large-size video is still unable to move; at the same time, the battery of the mobile phone is obviously becoming less and less durable. Play. This is just a simple and intuitive experience. In fact, there are many complex architectural design factors behind it. The author has been engaged in processor design for many years. I hope this article will help you analyze what really represents the future of smart phone processors from the perspective of processor architecture. I hope it will be useful for everyone when buying smart phones.

       In fact, a smart phone today is very close to a PC from a hardware perspective, but due to its special size and battery life requirements, its design difficulty is far more complicated than that of a PC. Hardware systems are experiencing a development path very similar to PC hardware systems. In the first ten years of the development of the PC system, it was almost purely driven by the improvement of the CPU frequency and technology. At that stage, the CPU frequency was the only criterion for measuring system performance. CPU vendors also focused all their attention on how Increase the processor's clock speed. This view drove the PC CPU industry to gradually enter the dead end of the process limit. It did not change until AMD introduced the new X86 processor architecture. AMD used advanced processor architecture to tell everyone that frequency is not the only measure of performance. Today, we no longer use the main frequency to measure performance, but rather focus on the processor's architecture advancement, disk file system performance, graphics system performance, and even power consumption. The performance of the current PC CPU is not low, and there is an image metaphor that the entire calculation workload of the Apollo moon landing program that took thousands of people over several years can be easily done with a current PC, which shows that today ’s The processor performance is strong, but an obvious fact is that the processor cannot bear all the performance requirements of the system application at any time, so the graphics card industry can prosper for a long time and become more and more the key to system performance. In fact, the current mobile phone system is also the same. For a smart phone, if the processor reaches 400MHz or more and the main frequency is increased, the difference in daily operation of the system will have a very small effect, but the high-intensity multimedia and graphics computing requires far more processing power Far from being able to be solved by increasing the main frequency of the 200-300MHz processor, the best technical solution in the world today is the SOC architecture with a dedicated hardware acceleration core. See the comparison of several mainstream high-performance smartphone processor architectures.
