最近想给我很老的电脑升级个CPU,打算只花50元左右找个二手的装上,于是研究了这个价位的几款CPU,且想弄清楚它们的性能。(是不是很闲啊,这么烂的CPU还要找个性能看看,其实都很烂的,没必要啦。)最后买下了一款标价60的 E6300 CPU,淘宝网链接:http://item.taobao.com/item.htm?id=22427015214

这些CPU用起来肯定都类似,但是有个性能很重要——超频能力。

在这之前简单谈谈超频

对于CPU的主频,用公式可以计算,即 主频=倍频×外频。 CPU 一般在出场的时候都已经锁住了倍频的,所以无法更改倍频的,只能更改外频,即通常的超频,默认外频一般为100MHz,调节范围从100MHz至600MHz。超频可以采用对CPU加电压的方法,另外,一般的主板现在都支持步进调节来超频。

关于超频,在外频固定的前提下,提升倍频也可以提升CPU的主频。默认倍频通过主频除以默认外频计算出来,最简单的办法是实用cpuz软件来检测。

CPU超频,可以通过不同的倍频外频组合得到最佳稳定运行的主频频率。超频还要根据自己的内存等硬件来综合考量。

要查看超频的技术细节,可以看这个文章:http://tech.sina.com.cn/h/2011-11-21/07101939012.shtml

顺便说说超频原理:

CPU倍频,全称CPU倍频系数。CPU的核心工作频率与外频之间存在着一个比值关系,这个比值就是倍频系数,简称倍频。理论上倍频是从1.5一直到无限的,但需要注意的是,倍频是以0.5为一个间隔单位。外频与倍频相乘就是主频,所以其中任何一项提高都可以使CPU的主频上升。现在CPU的倍频很多已经被锁定,无法修改。

外频又能理解为前端总线(FSB)。那么上面的公式也可以写成 主频=倍频×FSB。但是本质上,PSB和外频是不同的东西。

前端总线”这个名称是由AMD在推出K7 CPU时提出的概念,但是一直以来都被大家误认为这个名词不过是外频的另一个名称。我们所说的外频指的是CPU与主板连接的速度,这个概念是建立在数字脉冲信号震荡速度基础之上的,而前端总线的速度指的是数据传输的速度,由于数据传输最大带宽取决于所有同时传输的数据的宽度和传输频率,即数据带宽=(总线频率×数据位宽)÷8。目前PC机上所能达到的前端总线频率有266MHz、333MHz、400MHz、533MHz、800MHz、1066MHz、 1333MHz几种,前端总线频率越大,代表着CPU与内存之间的数据传输量越大 CPU的功能越强大。

超频的时候将要处理CPU真正的FSB速度,而不是有效CPU速度。

速度等式的倍频部分也就是一个数字,乘上FSB速度就给出了处理器的总速度。例如,如果有一颗具有200MHz FSB(在乘二或乘四之前的真正FSB速度)和10倍频的CPU,那么等式变成:

(FSB)200MHz×(倍频)10 = 2000MHz CPU速度,或是2.0GHz。

这是超频的基础,也是最简单的计算方法。想要深入了解的话,要知道这是一门学问,需要认真研究才行。

言归正传。虽说就买个几十块钱的二手CPU根本没必要排名了,但终归还是研究了一把。现在把一个网站上找到的东西贴到下面,让我对这些CPU的排名有个大致了解吧。
