X86 and ARM are two main CPU architectures, and the X86 architecture CPU is the leader in the PC server industry, and the ARM architecture CPU is the leader in the mobile terminal. They have significant differences in design concepts, performance, power consumption, and application fields.
Design concept:
The X86 (The X86 architecture) architecture is a computer language instruction set executed by a microprocessor developed by Intel. It is a complex instruction set computer (CISC) architecture. the number of operations within to increase overall performance. This means it has a large number of instructions, each of which can perform complex operations such as memory access, arithmetic operations, etc.
The ARM architecture is a 32-bit reduced instruction set developed by ARM Corporation, a reduced instruction set computer (RISC) architecture designed to optimize performance per watt within constrained power and thermal environments. Therefore, its instruction set is relatively small, and the operation performed by each instruction is relatively simple, but complex operations can be completed by combining multiple instructions.
Performance and Power Consumption:
l The X86 architecture processor usually has a higher clock frequency and stronger computing power, so its power consumption remains high all the year round. Generally speaking, processors with X86 architecture, especially those used for desktops and servers, have relatively high power consumption. Even for Intel Core series processors used in notebook computers, their power consumption is usually between 15W and 45W. between.
l The processor design of the ARM architecture pays more attention to energy efficiency, that is, the amount of calculation completed under the unit energy consumption. Therefore, ARM processors are usually more popular in power-sensitive applications, such as mobile devices (phones, tablets), embedded systems, etc.
Application fields:
l The X86 architecture is mainly used in personal computers, workstations and servers due to its powerful computing capabilities.
l Due to its low power consumption, the ARM architecture is mainly used in embedded system design, low power consumption and energy saving, and is very suitable for the field of mobile communication. Consumer electronics, such as portable devices (PDAs, mobile phones, multimedia players, handheld video games, and computers), computer peripherals (hard drives, desktop routers), and even military equipment such as onboard computers for missiles .
Software Compatibility:
l The X86 architecture has a rich software ecosystem, especially on desktop operating systems (such as Windows, Linux, macOS, etc.) and various application software, which makes X86 an ideal choice for many different application scenarios.
l The ARM architecture has a rich software ecosystem on mobile operating systems (such as Android and iOS), but relatively weak support on desktop operating systems and application software.
All in all, X86 and ARM are two different processor architectures. They have their own advantages and are suitable for different application scenarios. X86 is mainly aimed at PCs (Intel, AMD) and X86 servers; while ARM is mainly used in mobile devices (embedded fields such as mobile phones and tablet computers).
