前言
尝试比较异构架构x86-64，e2k（Elbrus），mips和arm上的处理器性能。
所有测试均以C语言编写（取自我未修改或优化的源代码），并使用针对该体系结构的特定编译器针对特定体系结构进行了编译，并且测试在Linux操作系统的各种发行版上进行。结果可能会受到编译器的类型和版本以及优化模式的影响。尽管以这种方式，您也可以粗略比较不同体系结构上的处理器的性能。
PS：我知道大多数测试都是针对非常老旧的计算机的，但是它们可以在任何地方使用。哪一个很好。
比较处理器的体系结构类型
中钢国际
CISC（复杂指令集计算）是一种架构，其中一小部分寄存器，各种长度的命令，操作由一个命令编码。
RISC
RISC（精简指令集计算）是一种处理器体系结构，其中的指令经过简化并且具有固定的长度（例如32位），可以提高性能。它具有大量的寄存器。
弗利
VLIW（非常长的指令字）-具有非常大指令的处理器体系结构。一条指令包含许多可以由不同处理器单元执行的简单指令。所有这些都大大简化了体系结构，但使编译器复杂化。无效的代码会生成不完整的指令，从而大大降低程序性能。
