借助Intel最新发布的处理器，可以肯定的是，大多数消费类台式机很快就会运行 2 核、4 核甚至 6 核的机器。
随着Kaby Lake、Coffee Lake和Cannon Lake的出现，四核消费 PC 将非常实惠。那么您当前的机器上有多少个内核？在本文中，我将向您展示可用于确定 PC 上的核心数量的不同方法。
什么是核心？
任何计算机上的主要部件都是CPU，它代表中央处理器(Central Processing Unit)。CPU获取指令然后执行计算。如果一个处理器一次只能处理一组指令，这意味着它只有一个内核。
如果一个处理器可以同时处理两组指令，那么它就被认为是一个双核处理器。如果它可以同时处理四组指令，那么它就是一个四核处理器。处理器拥有的内核越多，它一次可以处理的指令集就越多。
任务管理器
查看您拥有多少核心的最简单方法是打开任务管理器(Task Manager)。您可以按CTRL + SHIFT + ESC键盘快捷键，也可以右键单击“开始(Start)”按钮并从那里选择它。在Windows 7中，您可以按CTRL + ALT + DELETE并从那里打开它。
单击“性能”(Performance)选项卡，您将在左侧看到多个图表，在右侧看到更多图表和信息。单击(Click)CPU，您将看到CPU利用率图表。
默认情况下，它显示一个图形，但您可以通过右键单击图形并选择将图形更改为(Change graph to)然后选择逻辑处理器(Logical processors)来更改它。
但是，在Windows 10中，您实际上不必更改图表，因为它会告诉您系统中有多少个Sockets、Cores和Logical 处理器( Logical processors)。就我而言，我有一个插槽，这意味着我有物理CPU。我有 4 个核心，这意味着它是一个四核处理器。所以我总共有 4 个逻辑处理器。
它还为您提供有关 L1 缓存、L2 缓存和 L3 缓存的信息。这些是CPU上的专用缓存，允许CPU缓存指令以加快处理速度。
在Windows 7中，任务管理器看起来有点不同。首先，您必须更改视图，以便每个CPU显示一个图形。这是使用任务管理器判断Windows 7中(Windows 7)CPU有多少内核的唯一方法。
单击View，然后单击CPU History，然后单击One Graph Per CPU。现在您将能够看到您拥有多少个逻辑处理器。
使用Windows 7中的任务管理器，您可以查看总共有多少个内核，但您无法知道您拥有多少个处理器以及每个处理器上有多少个内核。
系统信息
无需任何软件即可获取有关CPU或CPUS信息的另一种简单方法是使用(CPUS)Windows中的“(Windows)系统信息(System Information)”对话框。只需(Just)单击开始并输入系统信息(system information)。默认情况下，应自动选择系统摘要。(System Summary)
在右侧，您会看到列出的一堆项目，告诉您有关您的 PC 的信息。您应该看到与列出的处理器有关的一行或多行。如果您有多个CPU，它将在单独的行中列出每个 CPU。所以现在我可以告诉我的机器有两个CPU(CPUs)，每个 CPU 有 2 个内核。
我的另一台 PC 也有四个内核，但只有一个处理器。所以我有一台带有四核处理器的 PC 和另一台带有两个双核处理器的 PC。很容易(Easy)，对吧？
谷歌和第三方工具
一旦您从系统信息中获得了确切的CPU型号，您也可以通过 Google 搜索它，您将在线获得该处理器的规格表（我在 Google 上搜索了核心 i5-4660）。
您还可以使用免费的第三方程序来获取有关您的处理器的各种详细信息。这些程序还可以告诉您您的CPU是否支持虚拟化、vt-x、SSSE3等。
两个最受欢迎的程序是Speccy和HWiNFO。这两个程序都运行良好，几乎可以为您提供您可以想象到的有关硬件的所有细节。
因此，这些是找出您的 PC 中有多少内核的快速简便的方法。请注意，如果您确实计划购买具有两个以上物理处理器的机器，则需要购买尚未推出的Windows 10 Pro for Workstations 。但是，消费类 PC 需要多个CPU的情况很少见。
(Windows)对于 32 位Windows ， (Windows)Windows 10 最多可支持 32 个内核，对于 64 位Windows，最多可支持 256 个内核。没有人会很快接近这个极限！享受！
Determine the Number of Cores in Your CPU
With the latest releases оf processоrs from Intel, it’s a certainty that most consumer desktops will be running machines with 2 corеs, 4 cores and even 6 cores very soon.
With Kaby Lake, Coffee Lake and Cannon Lake on the horizon, a quad-core consumer PC is going to be very affordable. So how many cores do you have on your current machine? In this article, I’m going to show you the different methods you can use to determine the core count on your PC.
What is a Core?
The main component on any computer is the CPU, which stands for Central Processing Unit. The CPU gets instructions and then performs calculations. If a processor can only process one set of instructions at a single, that means it has only a single core.
If a processor can process two sets of instructions at the same time, then it is considered a dual-core processor. If it can process four sets of instructions simultaneously, then it is a quad-core processor. The more cores a processor has, the more sets of instructions it can process at one time.
Task Manager
The easiest way to see how many cores you have is to open up Task Manager. You can press the CTRL + SHIFT + ESC keyboard shortcut or you can right-click on the Start button and choose it from there. In Windows 7, you can press CTRL + ALT + DELETE and open it from there.
Click on the Performance tab and you’ll see several graphs on the left-hand side along with more graphs and information on the right-hand side. Click on CPU and you’ll see the CPU utilization graph.
By default, it shows a single graph, but you can change that by right-clicking on the graph and choosing Change graph to and then selecting Logical processors.
However, in Windows 10, you really don’t have to change the graph since it tells you how many Sockets, Cores and Logical processors there are in the system. In my case, I have one socket, which means I have on physical CPU. I have 4 cores, which means it’s a quad-core processor. So I have a total of 4 logical processors.
It also gives you information about the L1 cache, L2 cache and L3 cache. These are specialized caches on the CPU that allow the CPU to cache instructions for faster processing.
In Windows 7, the task manager looks a bit different. Firstly, you’ll have to change the view so that it shows one graph per CPU. This is the only way to tell how many cores the CPU has in Windows 7 using task manager.
Click on View, then CPU History and then One Graph Per CPU. Now you will be able to see how many logical processors you have.
Using task manager in Windows 7, you can see how many cores you have in total, but you can’t tell how many processors you have and how many cores are on each processor.
System Information
Another simple way to get information about your CPU or CPUS without any software is to use the System Information dialog in Windows. Just click on start and type in system information. By default, System Summary should be selected automatically.
On the right-hand side, you’ll see a bunch of items listed that tell you about your PC. You should see one or more lines pertaining to the processor listed. If you have more than one CPU, it will list out each one on a separate line. So now I can tell my machine has two CPUs, each with 2 cores.
My other PC also has four cores, but only with one processor. So I have one PC with a quad-core processor and another PC with two dual-core processors. Easy enough, right?
Google & Third-Party Tools
Once you have the exact CPU model from system information, you also could just Google it and you’ll get a spec sheet online for that processor (I Googled core i5-4660).
You can also use a free third-party program to get all kinds of detailed information about your processor. These programs can also tell you whether your CPU supports virtualization, vt-x, SSSE3, etc.
The two most popular programs are Speccy and HWiNFO. Both of the programs work really well and give you just about every detail you can imagine about your hardware.
So those are the quick and easy ways to find out how many cores you have in your PC. Note that if you do plan on purchasing a machine that has more than two physical processors, you’ll need to purchase Windows 10 Pro for Workstations, which hasn’t come out yet. However, it’s rare for a consumer PC to need more than one CPU.
Windows 10 can support up to a max of 32 cores for 32-bit Windows and 256 cores for 64-bit Windows. None one is coming close to that limit any time soon! Enjoy!
