SiSoftware Sandra Pro Business 2009
SiSoftware Sandra是一款可运行在32bit和64bit Windows操作系统上的分析软件，这款软件可以对于系统进行方便、快捷的基准测试，还可以用于查看系统的软件、硬件等信息。从Sandra 2007开始支持SSE4指令集。SiSoftware Sandra所有的基准测试都针对SMP和SMT进行了优化，最高可支持32/64路平台，这也是我们选择这款软件的原因之一。

SiSoftware Sandra对比
测试平台的处理器子系统、内存子系统架构上都很相似，ASUS RS162-E4采用的X5460在频率上比我们的基准测试平台要高上不少，因此L1、L2以及处理器间带宽上ASUS平台表现良好。
内存带宽方面，Sandra结果表示ASUS平台的性能不及我们实验室的基准平台，部分是由于主板的问题，部分是由于芯片组的问题。我们的DELL平台采用了5000X芯片组，带有12MB Snoop Filter缓存，可以降低内存存取，从而提升FSB总线和内存总线的效率。在一些情况下，它就表现为内存带宽的提升。
