要掌握cpu知识，得先从cpu的样子开始认起，先从P4开始吧，毕竟P4之前的cpu已经不是那么常见了。
热消耗72.4 w的英特尔Socket 423 Pentium 4 CPU，这也是首颗支持 QDR内存的CPU

Socket 423的P4 CPU Willamette裸晶尺寸是16x14mm

说完那些古老的说说我们都看到过的吧！
英特尔的Celeron CPU（Northwood核心），配上128kB L2高速缓存，可不支持Hyperthreading技术。

Socket 478 P4 CPU背面图，从图中可见，针脚比以前的细多了。

Socket 775 CPU的针脚通通不见了：接点改成弹力触片。
