理论测试成绩微弱提升
SiSoftware Sandra Professional v2009能够对于被测系统进行方便、快捷、自动化的测试，是帮助我们了解被测系统各个子系统性能的不可或缺的测试软件。它的测试结果比较偏重于理论值，可重复性较好，便于帮助深入分析计算机系统的具体问题。

对比8371G在两个系统下的测试情况，我们看到Windows 7系统下，处理器相关的测试成绩有很小幅度的提高，.Net和JAVA部分的成绩提升则要相对明显一些，而其他的部分测试成绩两个系统基本处在同一个水平线上，考虑到我们没有安装专门的Windows 7驱动，所以这样的成绩表现是正常的，相信安装了驱动之后，测试成绩将有相应的提升。
