How To Find CPU Cores In Windows

When it comes to maximizing the potential of your computer, understanding its hardware capabilities is essential. One of the core features of a CPU (Central Processing Unit) that plays a significant role in performance is the number of cores it has. This article will guide you through the process of finding the number of CPU cores in Windows, elaborating on the importance of CPU cores, methods to obtain this information, and additional tips related to CPU performance.

Understanding CPU Cores

Before we delve into how to find the number of CPU cores in your Windows system, it’s vital to grasp what CPU cores are and why they matter.

A CPU core is an individual processing unit within the CPU. Modern CPUs often come with multiple cores, allowing them to perform tasks more efficiently than older single-core processors. Each core can process its own thread of instructions, meaning tasks can be split between multiple cores, which significantly enhances multitasking capabilities and performance.

In contemporary computing, having multiple cores is essential for demanding applications, including video editing, gaming, and software development. Knowing the number of cores your CPU has can help you determine if your computer is capable of handling specific workloads, or whether it may be time for an upgrade.

How to find out how many physical cores and logic cores your CPU has? Need to check the CPU core before you buy a new laptop? In this tutorial we’ll show you 4 simple ways to find number of physical cores and logical cores in your CPU on Windows 10.

Physical Core VS. Logical Core

A physical core is an actual physical processor core in your CPU. Each physical core has its own circuitry and its own L1 (and usually L2) cache can read and execute instructions separately (for the most part) from the other physical cores on the chip. A CPU with two physical cores is called a dual-core processor and four physical cores is called a quad-core processor.

A logical core (also known as logical processors) is more of a programming abstraction than an actual physical entity. Logical cores are the abilities of a single physical core to run multiple tasks or threads simultaneously. For example, if you have a quad core CPU and each of its physical cores can run two threads at a time, then you have 8 logical cores.

Method 1: Check Number of CPU Cores Using Task Manager

Press the Ctrl + Shift + Esc keys simultaneously to open the Task Manager. Go to the Performance tab and select CPU from the left column. You’ll see the number of physical cores and logical processors on the bottom-right side.

Привет, друзья. В этой публикации рассмотрим такой вопрос: как узнать количество ядер процессора. Как узнать, сколько ядер, и сколько потоков у процессора, если он поддерживает гиперпоточность. В среде Windows делается это очень просто её же системными средствами. Также для получения такой информации можно использовать специальные программы для диагностики компьютерных комплектующих. Давайте рассмотрим все средства решения поставленной задачи.

Итак, ядра и потоки процессоров, это два неразрывно связанных понятия. Ядра – аппаратные, т.е. физические, они обеспечивают выполнение задач, возложенных на процессор по обработке информации. Некоторые процессоры Intel поддерживают технологию гиперпоточности Hyper-Threading, это значит, что у таких процессоров физические ядра имеют по два логических потока, которые помогают ядрам более эффективно (на 30%) справляться со своими задачами. Узнаем же, сколько ядер и потоков при наличии последних имеется у нашего процессора.

В Windows 10 и 8.1 можем использовать системный диспетчер задач, вызывается клавишами Shift+Ctrl+Esc, либо опциями в контекстном меню на панели задач или меню по клавишам Win+X. Во вкладке «Производительность» переключаемся на раздел «ЦП» и смотрим графы:

• «Ядра», где будет указано число ядер процессора;
• «Логических процессоров», где будет указано число потоков.

Если процессор не поддерживает Hyper-Threading, потоков будет указано столько же, сколько и ядер.

Друзья, в принципе максимум информации о своём процессоре – ядра, потоки, частоты, поддерживаемые технологии и т.п. – можно узнать на его страничке спецификаций на сайте производителя, т.е. на сайте компаний Intel и AMD. Вам для этого нужно загуглить запрос нечто «модель процессора + сайт». А модель своего процессора в среде Windows узнать можно узнать элементарно – с помощью системного диспетчера устройств. Запустить его можно в Windows 10 и 8.1 в меню по клавишам Win+X, во всех системах Windows – с помощью ввода в системный поиск непосредственно названия диспетчера или технического названия его приложения:

devmgmt.msc

В диспетчере устройств, в разделе «Процессоры» и увидим название модели нашего процессора. Кстати, процессоров здесь будет числиться столько, сколько у него ядер или потоков.

Узнать количество ядер процессора можно с помощью бесплатной программы-диагноста CPU-Z. Она отображает характеристики базовых комплектующих компьютера, с её помощью можно много чего узнать о начинке своего ПК или ноутбука. В первой вкладке «CPU» этой программы будет содержаться информация о процессоре. И в самом низу увидим:

• В графе «Cores» число ядер процессора;
• В графе «Threads» число потоков для процессоров, у которых есть поддержка Hyper-Threading.

Опять же, если процессор без технологии гиперпоточности, потоков для него будет указано столько, сколько ядер.

Ну и ещё одна программа, показывающая сколько ядер у процессора, не могу, друзья, не упомянуть лишний раз о ней – HWiNFO. Совершенно бесплатная, при этом по уровню детализации информации о комплектующих компьютера сравнима с известной AIDA64, пригодится во многих случаях. В программе HWiNFO идём в раздел «Central Processor(s)», и там будут графы:

• «Number of CPU Cores», показывающая число ядер;
• «Number of Logical CPUs», показывающая число потоков для процессоров с технологией гиперпоточности.

И здесь также, если процессор без гиперпоточности, его число потоков будет таким же, как и число ядер.
