新制程新动力 六款至强5600服务器横评(3)

内存性能测试

    6款机型均采用了ECC DDR3-1333规格内存,为了获得最大的内存带宽,我们为服务器配置了能够实现最大通道数的内存数量,其中联想T260 G3只有8个内存插槽,只能实现双通道内存传输,所以只配置了四根内存。其余机型均配置了六根内存,实现三通道传输。内存容量上未作统一,在后面的CPU、内存带宽等测试中内存容量对结果影响并不是很大。

    SiSoftware Sandra Pro Business 2010中提供了内存带宽、内存延迟和缓存性能的测试,我们继续用这个工具来考量6款服务器的内存性能:


内存带宽测试对比

    内存测试小结:6款机型配置了同样的X5650 CPU、均采用ECC DDR3-1333规格内存,至强5600平台集成三通道内存控制器,理论上最大可以实现32GB/s的内存带宽。从结果来看,华硕、曙光、正睿、富士通的产品在内存带宽上几乎完全相同,这看上去是由相同的配置规格所决定的。但是浪潮和联想的产品比较出人意料,获得了更高的分数,其中联想T260 G3只支持双通道传输,配置了4根内存,但是却获得了较高的分值。
