服务器CPU和普通家用CPU的区别，服务器如何选择CPU配置？103.216.153.x

大家都知道服务器是指那些具有较高计算能力，能够提供响应成千上万用户服务请求的一种高性能计算机

服务器，虽然在硬件结构上和通用的个人计算机（PC）非常相似，但两者在性能和功能上相差甚远，其中服务器的CPU和普通家用的CPU也是一样的，今天咱们来分析一下CPU间的不同之处

1.指令集不同

家用或者用工作用电脑配备的普通CPU，通常为CISC复杂指令集，追求指令集的大而全，尽量把各种常用的功能集成到一块，但是调用速度和命中率相比服务器CPU较低一些，服务器CPU的指令一般是采用的RISC(精简指令集)，这种设计的好处就是针对性更强，可以根据不同的需求进行专门的优化，能效更高

2.缓存不同

缓存也决定着CPU的性能，由于服务器CPU对运算性能要求高，所以服务器CPU往往应用了最先进的工艺和技术，并且配备了一二三级缓存，运行能力更强，服务器CPU很早就用上了3级缓存，普通cpu是近几年才用上了缓存技术

3.接口不同

服务器cpu和普通cpu接口往往不同，服务器CPU接口大多为Socket 771、Socket 775、LGA 2011、LGA 1150相比普通CPU接口尽管不少相同，但实际上搭配的主板并不相同，服务器cpu配备的主板通常没有显卡卡槽，因为CPU自带的核心显卡即可满足需求，并且其CPU总线带宽比家用CPU高

4.稳定性要求不同

服务器CPU是为了长时间稳定工作而存在的，基本都是设计为能常年连续工作的，服务器CPU相比家用CPU在稳定性和可靠性方面有着天壤之别，一般服务器都是365天开机运行，只有偶尔停机维护，对稳定性要求极高

普通CPU则是按72个小时连续工作而设计的，家用电脑在不使用时，我们还是习惯让他保持关机状态，一般每天都会关机

5.多路互联支持不同

多路互联是服务器上的一项技术，比如服务器主板可以同时拥有多个CPU插槽，可以同时安装多个CPU，这个就是CPU多路互联技术，这项技术只有服务器CPU才支持，普通家用电脑，一块主板只可以安装一个CPU，不支持多路互联

6.价格不同

由于服务器CPU针对高稳定性设计，在用料上一般都是选用优质材质，并且支持多路互联和长时间工作，和相同性能的普通CPU比，价格自然也是更高，此外，高端服务器CPU更上运用大量的最新先进技术，价格更贵，因此一般服务器CPU价格都在千元以上，高端服务器CPU都是在万元以上，甚至几十万

要想选择合适的服务器CPU你应该知道以下几点：

1、服务器CPU的工作速度部分取决于主频，即时钟速度，也就是处理器执行指令的速度，主频越高，CPU每秒可以执行的指令越多

2、租用服务器我们不能局限于挑选处理器，而更要注重服务器的整体性能表现，除非你的服务器的总体运行速度相当高，否则采用高主频的处理器可能导致性能瓶颈，因此您需要确保服务器的设计合理，众多硬件合理搭配，以便发挥服务器最大的作用

3、处理器速度，以赫兹(GHz)为单位，随着CPU的改进升级，芯片架构的改进意味着无论主频如何，CPU可以同时执行更多的指令，这要归功于多核、多线程、子循环、增加的数据吞吐量和减少的延迟等等
