前言：

在上一篇文章中啊鲁测试了i9 13900K关闭/开启效能E核心后的性能对比，得出的结论是关闭小核心然并卵，除了极少部分游戏有一丢丢的提升，其他都是核心全开优势更高。

从12代酷睿处理器开始，Intel采用性能核与大小核的设计，再配上超线程技术，使得CPU多线程性能得到了长足提的进步。

早在很久以前，江湖上有一种传闻是CPU关闭超线程会让CPU单核性能有所提升，以损失不一定用得上的多核性能来换取更高单核性能，这种方法可取么？在13代酷睿处理器中性能核和效能核都有了，超线程还是性能核心才支持，后台多任务交给效能核心群应该是足够了，由此看来，性能核的超线程完全有理由关闭，从而获得更高的单核性能，今天啊鲁就来试试13代酷睿关闭超线程前后的性能体验会不会拉开明显差距。

测试平台：

测试平台用的CPU是i9 13900K，8个性能核心与16个效能核心，配合HT加持共有32线程。

主板用的是微星MPG Z790 EDGE WIFI D4刀锋。

黑色PCB和银白色的装甲，看起来蛮搭配。

MSI标志性的龙魂LOGO，即使是还未通电，颜值依旧在线。

供电模块均配有全金属散热片。

你还别说，这个角度看还能发现不一样的美。

16+1+1相供电配置，16相为核心供电，每相最大稳定输出电流为90A，即使是遇到i9 13900K旗舰也丝毫不慌。

第一路M.2散热片采用快拆设计，免工具，这个设计确实方便，虽然用户不是经常进行更换M.2固态硬盘的操作。

该主板最高支持5333MHz DDR4内存，这频率的DDR4应该还是能正面刚一下DDR5内存的，哈哈。

前置Type-C接口，支持PD快冲，前提是你的机箱前置接口也要支持才行。

五路M.2接口均支持PCIe4.0协议，其中四路M.2接口加入了金属加固处理。也都配备了免工具M.2固态硬盘快拆卡扣。主板带有2*PCIe X16与1*PCIe X1插槽，第一条由CPU直出，原生更支持PCIe 5.0速率。其余两条分别支持PCIe 3.0X1，PCIe 4.0X4，由主板南桥负责提供。

ALC4080音频处理芯片，附近布有高质量音频液态电容，独立的音频区域设计，带来更纯净的电流设计。

后置I/O接口颇为丰富，DP1.4+HDMI2.1视频输出接口、数据接口方面：3*USB 5Gbps、4*USB 10Gbps、2*TYPE-C，速率分别为10Gbps和20Gbps。2.5G速率的 RJ45网卡接口、WiFi6E无线网卡。下方的两个小圆按钮分别用于清空BIOS设定和一键刷新BIOS。

显卡用的是目前最新旗舰微星RTX 4090超龙，刀锋7代风扇，镀镍铜底座机上气流导向技术与导流鳍片，让显卡满载运行温度表现也相当出色。

为了喂饱i9 13900K+RTX4090这两大顶级旗舰硬件，电源方面我使用了振华Leadex VP1000W PRO，全模组设计，在13cm小身尺寸，它有着80Plus铂金认证+输出波纹控制优秀+输出电压稳定+保持时间非常充足，风扇支持ECO低负载低温停转诸多亮点。不得不说实在是小身材大能量。

测试成绩：

PS：上图成绩为默认状态，下图成绩为关闭超线程状态

CPU-Z单线程成绩，关闭超线程后基本没有影响。但多核性能下降了0.5%。

Vary渲染测试，关闭超线程后，渲染成绩下降23%。

凡事总有例外，H.264转码测试，关闭超线程后成绩提升4%。

cinbenchmark R23渲染测试，默认状态下的i9 13900K领先关闭超线程的幅度高达24%。

光线追踪3DM PR测试，两者分数几乎一样，

地平线5，关闭超线程后，i9 13900K比默认状态平均帧率高3帧。

古墓丽影暗影：关闭超线程后，i9 13900K比默认状态平均帧率高4帧。

尘埃5，两者的平均帧率一模一样。

总结：

可见在13代酷睿处理器关闭超线程后，在生产力上性能损失最高达24%。虽然也有提升的地方但也聊胜于无。再看游戏，关闭超线程后确实有游戏会有帧率提升，但提升幅度不多，总的来说没有必要关闭超线程来瞎折腾。毕竟关闭超线程收益远不如失去的性能多。感谢阅读全文，欢迎打赏点赞。

郑李侵2087如何看出电脑的CPU是四核四线程还是双核四线程的?
淳郎非15050869218 ______ 首先,核数的确定:打开设备管理器-->处理器,可以确定CPU的数目 然后,线程的数目:打开任务管理器-->性能,CPU的窗口数目就是线程数 这样就可以知道自己的电脑是几核几线程了 希望这样可以回答你的问题

郑李侵2087cpu核心数和线程数 -
淳郎非15050869218 ______ 四核的cpu,看你怎么复理解,有几种理解方式. 伪四核. intel的i3或者i5有双核四制线程的cpu,也就是每个核心可以几乎同时运行两2113个线程.当四核5261用. 真四核4102. intel和amd都有的,就是四核四线程. 真四核多线程. intel高端i7的标志,有四核心,而且每个核心有两个线程,共计八线程,相当牛的cpu了. 希望能帮1653到您,望采纳!

郑李侵2087如何看出电脑的CPU是四核四线程的还是双核四线程的? -
淳郎非15050869218 ______ 其实有个很简单的方法,用鲁大师测试出硬件. 然后打开任务管理器,选择”性能“选项卡,在主板没有关闭核心的情况下,可以直接看线程数.

郑李侵2087怎么查看CPU是四核心四线程还是双核心四线程
淳郎非15050869218 ______ 下载专用软件 CPU-Z 打开查看CPU属性 一般4核有4线程 双核就是2线程

郑李侵2087怎么知道CPU是多少核的?!
淳郎非15050869218 ______ 用CPU-Z看看就会知道了、右下角会显示核心数与线程数、第一个数字是核心数、第二个是线程数(现在intel的CPU大多数都是超线程、所以看任务管理器或者是设备管理器都是不准确的) 下载个CPU-Z、窗口右下角会显示、前一个数字就是核心数

郑李侵2087请问CPU核心数目怎么查
淳郎非15050869218 ______ 楼主可以使用一款名叫CPU-Z的软件来进行查看,对了,四楼说的有点错误,在任务管理器→性能里看到的只是线程数,线程数不一定等于核心数,比如Intel Core i7 980X,这款cpu只有6个核心,可是它运用了超线程技术,将线程数由6个虚拟成了12个,所以,从任务管理器里看并不可靠,最好使用一些专门来查看cpu的软件,就像我刚才说的CPU-Z就可以胜任(运行CPU-Z后,在核心那一栏里,数字是几就是几核的,CPU-Z很小,从网上一搜就有很多,不到1MB).

郑李侵2087CPU怎么看 -
淳郎非15050869218 ______ 具体怎么看主要看你用CPU来干什么的了. CPU的参数很多,主频、线程、缓存(L1、L2和L3)等等 综合的处理速度大概是(我只能说大概,因为处理器的评价标准太多了)主频X线程数 我还是一个个介绍好了—— 1. 主频,这个不说,线程...

郑李侵2087能否在命令提示符下查看CPU是几核? -
淳郎非15050869218 ______ 查看CPU具体规格可通过使用CPU-Z,在指令集一行就可以查看CPU指令集 下面使用windows内置命令查看cpu核数,具体步骤如下: 1、 运行cmd,输入wmic 再输入cpu get * 如下图 2、鼠标拉动下面的滑动条,你会看到numberofcores,numberoflogicalprocessors. 意思是,双核单线程 这样就能知道CPU是几核几线程.

郑李侵2087怎样识别CPU双核还是单核? -
淳郎非15050869218 ______ 通过cpu-z或鲁大师之类,注意最好下最新版本.如果cpu较老也可以下载旧版本.在cpu-z里有两个显示项目,核心数,线程数.而这个,就是不能用任务管理器查看cpu核心的证据.楼上的什么ctrl+...

郑李侵2087怎么知道自己的电脑是多少和的CPU
淳郎非15050869218 ______ 如果是AMD的CPU,那么用你目前打开的电脑任务管理器来看,就是四核的,如果是Intel采用超线程技术的CPU,那么就很可能是双核四线程的.建议用CPU-Z来检测,并以它显示的核心数为准.
