As we all know, Intel is the undisputed overlord in the PC and enterprise processor market, and ARM is the emerging overlord in the mobile terminal market. Intel focuses on high performance and provides outstanding performance support for individual users and enterprise users. ARM focuses on low power consumption and provides long standby for mobile phones and tablet users.
The main features and differences between the two are as follows:
After more than 30 years of development, X86-based computers, both in terms of performance and production processes, are much stronger than the ARM platform.
The advantage of ARM is not that performance is strong, but efficiency. ARM uses the RISC instruction set, which is at a disadvantage in completing comprehensive work, but in some applications where the tasks are relatively fixed, its advantages will be fully realized.
The X86 architecture is connected to the expansion device in a "bridge" manner. Especially after years of development and accumulation, the convenience, stability and cost control of the expansion have been very good. ARM uses a dedicated data interface to connect the CPU to peripherals such as data storage, which is generally fixed at design time and difficult to extend later. Therefore, using the ARM architecture, the principle of "enough to use" is basically pursued.
3, system compatibility
The alliance between X86 architecture and Microsoft has monopolized the personal computer operating system for nearly 30 years, forming a huge user base and deeply solidifying the usage habits of many users. At the same time, the development of hardware and software has gradually formed a unified standard. Under this combination platform, some development tools are becoming more and more popular, so the compatibility based on X86 architecture is also unparalleled.
ARM architecture almost all adopts Linux operating system, and almost all hardware needs to build operating system separately, which is incompatible with other systems, which undoubtedly restricts its development and application until Google's Android system is unified in the application market. On, it provides strong support for the ARM architecture.
4, software development and transplantation
The X86 architecture system has been launched for too long, and the user's application, development tools and supporting work have reached a very mature state, so more and cheaper software development tools and third-party applications can be found on this platform. Greatly reduced the development cost and cycle of the previous period. ARM, due to its hardware, system, and compatibility constraints, is far more stretched than the X86.
5, power consumption
Because the development of the two is not the same, X86 is to meet as many applications and fields as possible. So it has been advocating performance and speed, of course, based on energy efficiency balance, its power consumption is not likely to be low, although it is far from ARM. But over the years, Intel has been working on high performance and low power consumption, and has achieved remarkable results. ARM's development idea is to meet a specific application, the strongest in a particular field, and its hardware has a strong specificity, which is bound to reflect its greatest advantage: power consumption.
