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
SiSoftware Sandra会使用最新的Intel指令集，因此Intel处理器在这方面通常会有一些优势。曙光I650-F表现出很不可思议的性能：在纯粹的处理器能力方面它比同样处理器的DELL PE2900III基准平台略微低一点点，然而在缓存方面大为胜出，到了内存方面又因为较高的延迟而具有较低的带宽。这肯定是因为它采用的主板引起的，曙光I650使用的是GA-7BESH-RH主板，基于5000P芯片组，而基准平台使用的是DELL主板，基于5000X芯片组，特点是带有12MB Snoop Filter缓存，这个Snoop Filter会影响缓存的表现。不过最终的结果不仅仅跟它有关。
