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AMD处理器在这方面通常不占具优势。在纯粹的处理器能力方面Xeon平台均大为胜出，而缓存、内存以及处理器间的带宽则是Opteron平台领先，由于配置了8条内存，因此内存带宽也比以前测试过的AMD平台要高。
