What is the difference between a multi core processor and a normal processor.

For example, a strong man represents a single-core processor, a person can pick 30 pounds of water, and there are two small wrestlers, each person can only pick 25 pounds of water, now there are 100 pounds of water, and strong men need to use four times to pick up, and two small wrestlers only need to work twice at the same time.

Of course, if Hercules is strong enough, that is, the frequency of the single-core processor is high enough to pick 50 catties of water at a time, then in fact, it only takes two times, generally speaking, the processor does more tasks, such as 100 catties of water, 100 catties of stones need to be completed at the same time, Hercules needs to be completed one by one, and Xiao Lux can be done by two people separately, and the efficiency will be higher.

If you are playing games, especially when you encounter a game like Civilization 5 that has high requirements for the CPU, of course, the higher the main frequency, the better, and now the mainstream is a dual-core four-thread and four-core eight-thread processor, such as i5, i7, and generally i5-760 is already very good (this CPU is four-core and eight-threaded, the main frequency, but it can be intelligently accelerated to.)

ps: The so-called dual-core four-thread is, it was originally dual-core, but he can simulate four-core according to your needs, and the same can be obtained with four-core and eight-thread!

In fact, I don't care how strong the CPU is when playing games.,Generally, dual-core is completely fine.,But if you want to be 3-5 years old, if you don't fall behind,i5-750All models above are higher-end models,Of course,i7It's a more high-end model than i5。

Now the minimum is 2 cores.

The more cores you have, the more advantageous you have when multitasking.

For example, no matter how capable a person is, let him do several things at the same time, he is not very efficient.

If it's multiple people doing several things, it's definitely more efficient than one person.

Multicorechips refer to the integration of two or more complete computing engines (cores) in a single chip.

Multicorechips refer to the integration of two or more complete computing engines (cores) in a single processor. Multicore technology was developed after engineers realized that simply increasing the speed of a single-core chip (onechip) would generate too much heat and not deliver the corresponding performance improvements, as was the case with previous processor products. They recognized that at that rate in previous products, the processor would quickly generate more heat than the surface of the sun.

Even without the heat issue, the price/performance ratio is unacceptable, and the slightly faster processor** is much higher. Intel.

Engineers have developed multicore chips that meet the needs of a "scale-out" (rather than "scale-up") approach to improve performance. This architecture implements the "divide and rule" strategy. By dividing tasks, threaded apps are able to take full advantage of multiple execution cores and perform more tasks in a given amount of time.

A multicore processor is a single chip (also known as a "silicon core") that can be plugged directly into a single processor socket, but the operating system uses all the resources involved to treat each of its execution cores as a discrete logical processor. By dividing the task between the two execution cores, multi-core processors can be clocked at a particularly low level.

Multi-core CPUs and multiple CPUs are incomprehensible to many novices.

I think to put it simply, it can be anthropomorphic: multi-core is equivalent to a person having multiple hands; Multiple CPUs are equivalent to multiple hands of others.

For example, your motherboard can only use one CPU, and the number of cores is ten cores and twenty threads, while the other motherboard supports two CPUs at the same time, each CPU is ten cores and twenty threads, and two is twenty cores and forty threads.

If it is a relatively mechanical work that does not require communication between various processes, such as putting 1,000 posters on the wall, then 3 people and 2 people are responsible for supporting the posters and 1 person is responsible for pasting them, which can obviously improve efficiency.

In the case of CPUs, multi-core CPUs perform better for tasks like gaming that require more immediate reactions, and for mechanical tasks like decompression, multiple CPUs (with more total cores than a single multi-core CPU) perform better.

Of course, a single multi-core CPU is a good way to circumvent all the drawbacks mentioned by basically multiple single-core CPUs. It doesn't need to worry about hardware overhead and complexity, and it can also solve the problem of working together between multiple threads and reduce memory overhead.

Because multi-threaded programs run in multi-core CPUs and share a single memory area, data can be transferred faster than buses and there will be no redundant data.

Check the number of computer coresThe specific steps are as follows:

Open Task Manager。It can be opened by right-clicking on an empty space on the taskbar and then selecting "Task Manager".

2. In Task Manager, select ".Performancetab.

3. In the Performance tab, you can see real-time charts and data of CPU usage. Here, you can see the number of "Logical Closed Car Processors" and "Physical Processors (Cores)", where ".Physical processors (cores).It refers to the number of cores of the computer.

In addition, in the Mac operating system, the car can view the number of cores of the computer through the following steps:

1. Click on the Apple menu and select "About This Mac".

2. In the pop-up window, select "System Report".

3. In the system report, select "Processor" under "Hardware" to see the number of cores of the computer.
