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
由于处理器频率较低以及只有双通道内存的缘故，Aisino 6501R-8的理论性能和带宽都不是很高；通过察看vs SPEED项目，我们可以看出每MHz的性能对比，这里Aisino 6501R-8大部分项目都比基准平台略微低一点，这是双通道内存配置的影响。
