喜欢玩游戏的小伙伴肯定希望自己电脑的配置越高越好,配置越高游戏体验就越好,其中cpu在电脑配置上是极其重要的,很多小伙伴不知道选择什么cpu好,那么下面小白就给大家带来cpu性能排行榜2021。
cpu性能排行榜2021：
如何选CPU
一、CPU的主频。
CPU的主频我们平时也称之为频率，CPU的主频越高其性能就越好，CPU的主频越高在更短的时间内处理完成的运算或者指令就越快。
小编举个干活劳动例子吧：小军(人名字)在30秒内可以洗10个碗(主频高)，小花(人名字)30秒内可以洗2个碗(主频低)。
也就是说同等CPU型号却不一样的主频差距就在于单位时间内完成工作的数量与质量问题。
这也就是很多人问的为什么一样的CPU就后面的主频不一样价格差距大的原因。
但是CPU的主频大也不完全都是好事，其实也是有副作用的，CPU的主频与温度直接成正比关系，
主频增大后CPU的发热也会随之增加，这样对我们的散热系统也面临挑战了。
如果CPU主频过高散热系统跟不上那么就会导致CPU内功耗墙与温度墙被限制，这样的超高主频下CPU的性能也不会达到期望的理想。
所有我们大家在对CPU超频运行的时候要注意一些。
二、CPU的核心数。
我们首先接上面一个洗碗的例子继续举例子，我们CPU要是双核的话那就是2个人同时洗碗，要是四核的话那就是4个人同时洗碗，要是八核的话那就是8个人同时洗碗，以此类推。
这样的解释我想大家应该非常明白了。这里有个知识点需要了解一下，假如单核的CPU30秒内洗2个碗，那是不是意味着四核CPU30秒内就是可以洗8个碗呢?
答案是：肯定低于8个碗，因为他们在合作的时候会有损耗，就相当于马拉车一样，一匹马一小时把车拉2公里，二匹马一起合作一小时不会达到4公里，就是这个道理。
CPU的N核心实际执行效率实际上不可能达到单核心的N倍。
三、如何正确的选择适合自己的需求CPU才是最正确的。
由于生活中我们每个人使用电脑的需求不一样，那么我们选择CPU硬件也是不一样的。
像我们日常办公电脑需求简单，我们假如选择了多核心的CPU其实没有必要。
因为CPU在处理您的简单需求操作的时候很多核心已经处于闲置状态或者处于半闲置状态，您高价买的多核心CPU利用率是不高的，这样就会造成核心浪费、资源浪费和经济浪费。
如果是画图类型的专业设计，那么对CPU的要求就是比较高了，单一核心的CPU已经满足不了需求了。
在运算图纸信息的时候都是同时需要多个核心同时启动而一起协作完成主人分配的任务(一个人扛一百斤东西和4个人一起扛100斤东西的道理)。
以上就是cpu性能排行榜2021，希望能帮助到大家。
