Intel双核/四核Penryn处理器现场评测
3
下面的测试成绩来自北京IDF现场，系统配置稍有区别，Penryn双核、四核平台频率都锁定在3.33GHz，系统也变更为Windows Vista Ultimate 32-bit。

这里我们可以更清晰的比较两代四核的性能——Yorkfield vs. Kentsfield。在主频方面，Yorkfield要高出13.6%，而成绩方面Half-Life 2相差21.8%，Cinebench则达到25%。DivX 6.6测试中，由于支持SSE4指令集，其性能提升高达111%。
通过以上简单的测试，我们可以基本了解Penryn的性能水平。在同频率下，Penryn比Conroe至少有5-10%的提升，如果考虑频率因素，预计到年底左右，新一代处理器性能将有20%左右的提升。Penryn的对手将是AMD新架构Barcelona，二者真正的较量即将开始。
