除非您拥有一台旧计算机，我们指的是 90 年代的计算机，否则您可能在其中装有多核处理器(multicore processor)。你知道你的CPU有多少个内核和逻辑处理器吗？你想知道这些信息吗？在本文中，我们将向您展示七种方法，您可以使用它们来查看您的计算机处理器有多少内核，或者它为 Windows 提供了多少逻辑内核：
注意：本教程帮助您了解您的(NOTE:)CPU有多少个内核和逻辑处理器。CPU内核是处理器内部的物理内核。逻辑处理器是“内核中的内核”，这意味着它们代表了单个内核同时执行多个（2 个或更多）任务的能力。例如，一个四核处理器(quad-core processor)有四个物理核心，如果它的每个物理核心可以同时运行两个线程或任务，它可能有八个逻辑处理器。
1.使用任务管理器查看你的(Task Manager)CPU有多少个内核
查看您的CPU(CPU)有多少个内核以及其上的逻辑处理器数量的最快和最简单的方法可能涉及使用任务管理器(Task Manager)。通过同时按下Ctrl + Shift + Esc键或按照此处描述的方式之一启动任务管理器：在Windows (Task Manager)10(Task Manager)和Windows(Windows 10) 8.1中(Windows 8.1)启动任务管理器的 10 种方法。
如果您使用 Windows 10 或Windows 8.1，请在任务管理器(Task Manager)中转到性能(Performance)选项卡。在窗口的右下角，您可以找到您要查找的信息：核心(Cores)数和逻辑处理器(Logical processors)数。
如果您使用 Windows 7，在任务管理器(Task Manager)中，您应该会看到CPU上每个逻辑处理器的不同图表。只要(Just)数一数，您就会得到您想要的信息。
2. 使用系统信息(System Information)找出您的处理器有多少个内核
系统信息(System Information)应用程序提供了另一种快速查找CPU上的内核和逻辑处理器数量的方法。启动它，然后在System Summary部分中，查找Processor行。它列出了 CPU 的确切名称和(CPU)频率(name and frequency)以及其上的内核和逻辑处理器的数量。
3.使用设备管理器了解您的(Device Manager)CPU有多少个逻辑处理器
如果您只想知道在您的CPU上找到的逻辑处理器的数量，您可以使用设备管理器(Device Manager)来获得答案。
打开设备管理器(Device Manager)并展开处理器(Processors)列表。然后，计算列表中显示的处理器数量。
4. 使用命令提示符或 PowerShell(Command Prompt or PowerShell)查看您的处理器有多少个内核
如果您更喜欢使用命令行(command line)，您可能还更喜欢使用PowerShell或命令提示符来查找(Command Prompt)CPU上的内核和逻辑处理器的数量。
打开 PowerShell 或命令提示符(Open PowerShell or Command Prompt)并输入以下命令：wmic cpu get NumberOfCores,NumberOfLogicalProcessors。确保NumberOfCores(NumberOfCores)和NumberOfLogicalProcessors之间没有空格。该命令的输出告诉您在您的CPU(CPU)上找到了多少个内核和多少个逻辑处理器。
5.通过阅读环境变量了解你的CPU有多少个逻辑处理器
查找CPU(CPU)上找到多少逻辑处理器的另一种方法是使用称为Number of Processors的(Number of Processors)系统环境变量(system environment variable)。不幸的是，这并不能告诉您CPU(CPU)上有多少个内核。
如果您想知道在CPU上找到的逻辑处理器的数量并且您更喜欢命令提示符(Command Prompt)，请启动它并输入以下命令：echo %NUMBER_OF_PROCESSORS%。
如果您想知道在您的CPU上找到的逻辑处理器的数量并且您更喜欢PowerShell，请启动它并输入以下命令：echo $env:NUMBER_OF_PROCESSORS。
6.使用BIOS 或 UEFI查看您的(BIOS or UEFI)CPU有多少个内核
有些计算机还会在BIOS 或 UEFI(BIOS or UEFI)中告诉您处理器上的内核数量。首先(First)，您必须访问计算机上的BIOS/UEFI。
输入计算机的BIOS/UEFI后，查找显示处理器信息的页面。根据您的主板制造商，此页面可能有不同的名称，因此您必须手动查找。有时，但并非总是如此，BIOS/UEFI还会共享有关CPU的详细信息，包括其上的内核数量。以下是技嘉主板(Gigabyte mainboard)的示例：
7.使用第三方应用程序查看您的CPU有多少个内核和逻辑处理器
我们知道的最后一种轻松识别CPU中的内核和逻辑处理器数量的方法是运行专门收集系统信息的第三方应用程序。那里有很多这样的工具，要找到一些，你所要做的就是使用谷歌(Google)。为此，我们最喜欢的两个工具是Speccy，您可以从这里下载(download from here)，CPU-Z，您可以从这里(get from here)下载。
您最喜欢哪种方法来找出您的CPU有多少个内核和逻辑处理器？
这些是我们可以想到的用于找出CPU内核和逻辑处理器数量的方法。你最喜欢他们中的哪(Which)一个？您知道查找此信息的其他方法吗？您愿意与其他读者分享吗？使用下面的评论部分并发表评论。
7 ways to tell how many cores your processor has
Unless you own an old computer, and by that we mean a cоmputer that's from the nineties, you probably have a multicore processor inside it. Do you know how manу cores and logical prоcessоrs yоur CPU has? Do you want to find out this information? In this article we will show you seven methods that you can use to see how many cоres your computer's procеssor has, or how many logiсal cоres it makes available to Windows:
NOTE: This tutorial helps you find out how many cores and logical processors your CPU has. CPU cores are physical cores found inside the processors. Logical processors are "cores within cores," meaning that they represent the ability of single cores to perform multiple (2 or more) tasks simultaneously. For example, a quad-core processor has four physical cores and may have eight logical processors, if each of its physical cores can run two simultaneous threads or tasks.
1. See how many cores your CPU has, using Task Manager
Probably the fastest and easiest way to see how many cores your CPU has, as well as the number of logical processors on it, involves using the Task Manager. Launch the Task Manager by simultaneously pressing the Ctrl + Shift + Esc keys or by following one of the ways described here: 10 Ways to start the Task Manager in Windows 10 and Windows 8.1.
If you use Windows 10 or Windows 8.1, in Task Manager, go to the Performance tab. On the bottom-right side of the window, you can find the information you are looking for: the number of Cores and Logical processors.
If you use Windows 7, in the Task Manager you should see different graphs for each of the logical processors found on your CPU. Just count them and you get the information you wanted.
2. Find out how many cores your processor has, using System Information
The System Information app offers another quick way to find the number of cores and logical processors found on your CPU. Launch it and, in the System Summary section, look for the Processor line. It lists the exact name and frequency of your CPU alongside the number of cores and logical processors on it.
3. Learn how many logical processors your CPU has, using Device Manager
If you only want to know the number of logical processors found on your CPU, you can use the Device Manager to get your answer.
Open the Device Manager and expand the Processors list. Then, count the number of processors shown in the list.
4. See how many cores your processor has, using Command Prompt or PowerShell
If you prefer using the command line, you might also prefer to find the number of cores and logical processors on your CPU using PowerShell or the Command Prompt.
Open PowerShell or Command Prompt and enter this command: wmic cpu get NumberOfCores,NumberOfLogicalProcessors. Make sure that there is no space between NumberOfCores and NumberOfLogicalProcessors. The output of the command tells you how many cores and how many logical processors are found on your CPU.
5. Learn how many logical processors your CPU has, by reading environment variables
Another way to find how many logical processors are found on your CPU is based on using a system environment variable called the Number of Processors. Unfortunately, this does not also tell you how many cores there are on the CPU.
If you want to know the number of logical processors found on your CPU and you prefer the Command Prompt, launch it and enter this command: echo %NUMBER_OF_PROCESSORS%.
If you want to know the number of logical processors found on your CPU and you prefer the PowerShell, launch it and enter this command: echo $env:NUMBER_OF_PROCESSORS.
6. See how many cores your CPU has, using the BIOS or UEFI
Some computers also tell you the number of cores on your processor inside the BIOS or UEFI. First, you have to access the BIOS/UEFI on your computer.
Once you have entered your computer's BIOS/UEFI, look for a page that shows information about your processor. Depending on your motherboard's manufacturer, this page can have different names, so you have to look for it manually. Sometimes, but not always, the BIOS/UEFI also shares details about your CPU that include the number of cores on it. Here is an example from a Gigabyte mainboard:
7. See how many cores and logical processors your CPU has, using third-party apps
The last method we know to easily identify the number of cores and logical processors found a CPU is to run third-party apps that are specialized in gathering information about your system. There are many such tools out there and to find some, all you have to do is use Google. The two tools that we like best for this purpose are Speccy, which you can download from here, and CPU-Z, which you can get from here.
Which is your favorite method for finding out how many cores and logical processors your CPU has?
These were the methods that we could think of for finding out the number of CPU cores and logical processors. Which of them is your favorite? Do you know other ways to find this information? Would you care to share them with other readers? Use the comments section below and leave a comment.
