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，用蓝色标出了性能特出的项目
和频率较高的Intel Xeon 2.66GHz平台相比，2.0GHz的Barcelona的确不占据优势。在整数运算和浮点运算方面Xeon平台均大为胜出。
