[3.理论性能测试之Sandra 2009]

SiSoftware是一套功能强大的系统分析测试工具，拥有30种以上的测试项目，支持多核心CPU。我们挑选的测试项目是与CPU平台性能发挥最密切相关的Processor Arithmetic，测试了各CPU的iSSE3指令集性能以及ALU算术/逻辑运算性能。

理论性能计算方面，三核的X3 440领先双核的G6950近50%，四核的X4 630也要比双核四线程的i3- 530领先10%以上。当然对比同架构产品来说，2.8GHz的X4 630虽然频率频率比X3 440的3GHz要低，但是理论性能仍然要高出四分之一左右，Intel的i3-530对比G6950也是如此。
