后记
从测试中我们可以看到P4 660在同时脉下，加入更多的Cache无疑是可加增效能，但并不是所有软件都会有大幅的增长。从测试中我们可以看到3D软件及编码的增幅较大，约有6%-8%的幅度增长。但一些纯运算软件及办工室软件则没有太大受惠。因此P4 6xx系统的处理器，应该是针对Gamer、3D Rendering及常压片的用家有更佳的较果。
Prescott 2M核心还是承继了Prescott的热力，而且明显地功耗因晶体管的数目增加而成正比，功耗由04B的115W增至05B的130W，虽然加入EIST加强型Speed Step，但看来Intel还是必须解决热力问题，就算是用了BTX增强散热效能，也不是长远之计。
