处理器架构性能测试分为处理器和内存两部分，首先我们看到的是处理器性能。我们对比前两项——至强X3430和至强E5504。从测试结果来看，许多项目至强X3430都处于领先优势，领先幅度也很明显，大概是20-40%左右。而第三项使用的是上一代的至强E5430处理器，双路配置。除了多媒体测试E5430没有相关成绩之外，其他测试至强X3430虽然大部分处于下风，但要是衡量单颗处理器的性能，至强X3430还是要高一些。
最后对比至强E5540处理器，虽然同是Nehalem架构，不过至强E5540支持超线程技术，也就是说实际上第四项系统中有16个处理器核心（8个处理器核心为虚拟），在这种情况下，两者的性能差距也不过就是1：2 的比例。由此看来至强X3430性能还是很强劲的。
