In any case, X86 computers are much faster and more powerful than ARM-based systems. X86 cpus are more than 1G, dual-core, quad-core popular, usually using 45nm (or even more advanced) process processes for production, and ARM: The CPU is hundreds of megabytes, and only recently appeared about 1G CPU, the process Tong uses less than 65nm process process, it can be said that ARM is not the opponent of the X86 structure system in terms of performance and production process. However, the advantage of ARM is not strong performance but efficiency, ARM uses RISC pipeline instruction set, which is at a disadvantage in completing comprehensive work, and its advantages can be fully utilized in some applications where tasks are relatively fixed.
