文中说到，根据贴主migeyusu的说法 CORE DUO 相对 i3-4 的在老软件性能仅有后者50-60%。
而AMD 的APU和FX 整数效能凭借高主频稍强于 老旧的CORE DUO，
其中贴出了部分代码，我照抄了部分，做出来玩玩。
PS: 其中基本排序算法我不懂是啥，那贴主说是二分查找我就照弄了.........{:dizzy:}

十多年没写VB6了，不足请提出。
附件中 Test1.2(i5) vb6 为原版测试工具， 工程2为以上代码生成的，体积小的是加了UPX壳的。
这样的测试方法不客观吧。 mk一下慢慢看

这个貌似差多了
可能是你运行时候后台东西太多或者开了自动睿频，这个单核性能和456带差好远， E3和4160基本整数都有2万出头，不过三代和四代性能是差10-15%的。
