一个基于C++用于检测Pentium CPU时钟主频的小程序，高精度显示，原理是通过嵌入汇编语言后检测"RDTSC"和"PCLKS"来实现，较底层的操作。不过无从知道能否检测更高主频的CPU。若有需要的自己下载源码研究下。-A C++-based program for the detection of small Pentium CPU clock speed, high-precision display, the principle is the detection by embedding assembly language "RDTSC" and "PCLKS" to achieve, compared with the underlying operating. But no way to know whether a higher frequency of detection of the CPU. If download the source code under their own research needs.
