　　近几年，AMD锐龙系列CPU可谓是突飞猛进，这一次的锐龙四代5000系列CPU单核也开始赶超intel，逼得intel开始走向亲民性价比路线，对自家十代新产品进行了降价策略，不少电脑爱好者表示“AMD，Yes！感谢AMD，让我用上更便宜的intel”，这句话能够充分的表达目前装机市场现状。小编今天给大家分享怎么免费升级老旧台式电脑硬件白嫖性能。

　　intel CPU的保值率还是相当高的，号称“传家宝”。一般来说，新一代CPU发布，因为架构的变化，性能的提升等各种因素，老一代CPU就会降价，我觉得这是十分符合消费级CPU电子产品的价值规律，但是对于部分的intel CPU来说，这个规律好像并不太适用了。

　　为什么我说intel保值率高，甚至有些CPU用个几年成为“理财产品”，例如老电脑一看是intel第七代酷睿i7-7700的CPU，大概用了有三四年了，但是去闲鱼二手平台，基本这个型号CPU二手可以卖到大概在1400-1500左右的价位。

　　由于intel对每一代CPU更新换代的缘故，每一代都会有不同程度的性能提升，所以导致了现在“i3默秒全”的现象，就拿十代i3 10100F来说，性能基本接近七代i7 7700、i7 7700K默频，性能并超过更老一代所有的消费级CPU型号。

　　要知道，目前的十代i3 10100F散片目前的全新价位大约只有550元左右的价位，性能几乎不变的情况下，你将手上的七代i7-7700卖了，还有赚到大几百。可能还有人会说主板不是需要更换吗，不要钱吗？我们来算一笔账。

　　一款i7-7700二手大约可以卖到1400-1500左右，一款二手B250主板可以卖到100-150左右，大概就是1500-1600元左右。

　　而i3 10100F+H410全新一线品牌的板U套装大约1100左右，还赚500-600元，这是同等性能来说的，如果用500-600元差价，将CPU升级为i5-10400F，性能提升了30%左右，是不是相当于白嫖了性能升级了新硬件，还多了三年质保。

　　以上只是一个案例，可以这样操作的老旧CPU很多，基本是六代七代i5、i7等都可以去操作一波，例如i7-6700、i7-6700K、i5 7500、i7 7700、i7 7700K等型号，只要你操作好，基本可以不花钱白嫖性能，不知道CPU性能好坏的，可以去看看CPU天梯图进行参考。
