This article will explain in detail what is meant by several cores and lines in cpu. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The number of cores of cpu refers to the number of processor cores of CPU, which refers to several physical cores within CPU, while several threads refer to the number of threads on the same processor that execute synchronously and share the processor's execution resources. Processor multithreading can prepare more data to be processed for high-speed computing core and reduce the idle time of computing core.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Introduction to CPU Core

The core number of CPU refers to several physical cores, each of which can be treated as a single-core CPU. Dual-core CPU is equivalent to a combination of two sets of hardware resources in a box. This core number is easy to understand, but it is difficult to understand the number of threads. Please see below.

Introduction to CPU Thread

CPU has several threads that originally correspond to the number of cores, that is, there are several threads in CPU, but Intel released a hyper-threading technology in 2002, which simulates a CPU kernel into two logical cores through special hardware instructions, so that when dealing with some multithreaded tasks, it can achieve parallel processing of data, greatly improve computing efficiency, and make the performance of CPU more thorough. But the simulated core is not the real physical core after all, and the overall performance is not as good as the real multi-core CPU.

Because the number of threads in cpu refers to the number of threads on the same processor that execute synchronously and share the processor's execution resources.

Description:

The processor core (Core), also known as the kernel, is the most important part of CPU.

The bulging chip in the center of CPU is the core, which is manufactured by monocrystalline silicon with a certain production process. All the calculation, receiving / storing commands and processing data of CPU are performed by the core.

Multiple threads of the processor can maximize the superscalar processing of wide emission and disorder, improve the utilization of processor computing units, and alleviate the access memory delay caused by data correlation or Cache miss.

Benefits of processor multiple threads:

1. The most attractive thing about processor multiple threads is that you only need to change the design of the processor core on a small scale, which can significantly improve performance with almost no additional cost.

2. Multithreading technology can prepare more data to be processed for the high-speed computing core and reduce the idle time of the computing core. This is undoubtedly very attractive for low-end desktop systems.

Benefits of multiple cores of processors:

1. Intel engineers have developed multicore chips to meet the "scale-out" rather than "vertical expansion" approach to improve performance. The architecture realizes the strategy of divide and conquer.

2. By dividing tasks, threaded applications can make full use of multiple execution kernels and perform more tasks in a specific time.

3. A multi-core processor is a single chip (also known as a "silicon core") that can be inserted directly into a single processor slot, but the operating system uses all relevant resources to use each of its execution cores as separate logic processors. By dividing tasks between the two execution cores, multicore processors can perform more tasks in a specific clock cycle.
