Is there a big difference between the use of 4 core mobile phones and 8 core mobile phones?

4 cores vs. 8 cores are not absolute. First of all, there are many indicators of the processor, in addition to the number of cores, but also the process, architecture, cache, etc. . .

4 cores or 8 cores, first of all, depending on the architecture and process, smaller support for better architecture, better performance, lower power consumption.

Then it's obvious that you've misunderstood something very important, because you thought that the 4 cores and 8 cores are all on at all times, but you misunderstood, the current CPU will automatically adjust the frequency and switch. For example, if you browse Weibo to read web pages, you may only open 2 cores, or 4 cores will run at low frequency, and if it is a high-load task like a game, all of them will be turned on to run at high frequency. This saves energy and guarantees performance.

Finally, the most critical point is that the mobile phone will heat up, once it reaches a certain level, for example, most mobile phones are not more than 50 degrees, it will automatically reduce the frequency, such as 8 cores and high frequency, then it will turn off a few cores to achieve the purpose of cooling down. This will also affect performance...

Well, having said so much, you have to know that in fact, the current mobile phones are overperformed! My Mi 3, the Snapdragon 800 from three years ago, can still run most online games, and my Mi 4c last year's Snapdragon 808 is enough to run all games. I also have Redmi N1, Snapdragon 400, and now it's not a problem to scroll through Weibo to read the web page and chat.

Okay, you got your question, right? This is not to say that the smoothness of 8 cores is necessarily better than that of 4 cores, because there are many factors.

The second level downstairs is reasonable, but there is no reference for a few words.

The so-called difference between 4 cores and 8 cores is actually not as big as imagined, because the multi-core cooperation efficiency of some processors is not high enough, even if there are 8 cores The speed is not as fast as 4 cores, and some 4 cores are 64 bits, which is not suitable for 8 cores and 32-bit processors. The processor brand and level of mobile phones are also very different, so some 4-core high-end processors will have faster results than 8-core low-end processors.

Nowadays, mobile phones have entered the multi-core era, and there are quad-core and eight-core at every turn, so how big is the difference between quad-core mobile phones and octa-core mobile phones, and what is the difference between performance and user experience, we have conducted a simple analysis of the number of CPU cores on mobile phones.

There is no doubt that the processor (CPU) is the brain of all computer devices, and the same is true for smartphones. With the development of technology, mobile processors based on ARM cores have also been greatly improved, from breaking through the 1GHz main frequency, dual-core, quad-core and now eight-core, it seems that there is a posture to compete with desktop processors.

Of course, the architecture is different, the performance is also different, and most consumers can understand that even if they are all four cores, the mobile phone and the PC processor are actually completely different. So back to mobile, does the phone's octa-core processor boast twice the performance of the quad-core processor?

Difference Between Quad Core and Octa-Core.

To put it simply, a quad-core processor has four processing cores that work together. The eight-core part is divided into two types, one is actually "double quadruple core", that is, there are eight cores, but they cannot work together, and four of the cores are often used in basic communication and other parts; The so-called "true octacore" is theoretically that the eight core files can be turned on at the same time for collaborative processing.

From the perspective of core architecture, both quad-core and octa-core processors are based on ARM, of which true octa-core processors include Qualcomm Snapdragon 810, Samsung Exynos 5433, NVIDIA Tegra X1, and many more. Of course, some details are slightly different from each manufacturer.

There is not much difference in performance.

According to the results of professional benchmark software tests such as Geekbench 3, the octa-core processor does have a higher score, and the performance is stronger in theory. However, for mobile devices such as mobile phones and tablets, the real trade-off is the balance between performance and battery life, so in practice, users may not feel a huge difference. Another classic case is that Apple's iOS devices have always used dual-core processors, but due to the excellent optimization of iOS itself, it seems that it is not inferior to Android phones equipped with octa-core processors in terms of actual operation speed and game performance.

Brief summary. As it stands, there is no huge difference in performance between Android phones with octa-core and quad-core processors, at least not by a factor of two. But obviously, processor and mobile phone manufacturers need to continuously improve their products, whether from their own technical development or marketing, just as a few years ago we questioned whether a quad-core processor was necessary for mobile phones, and now it is almost universal.

At the same time, as mobile systems are becoming 64-bit, the requirements for processing and integrated display chips are getting higher and higher, and octa-core processors will also be a trend. Of course, what we want to see is the balance between performance and power consumption, after all, battery life is the most important thing for a smartphone.

1. The most important thing for a high-performance smart phone is definitely its "core", that is, the CPU, just like the computer CPU, it is the control center system of the entire mobile phone, and it is also the control center of the logic part. The microprocessor achieves control by running software in memory and calling up the database in memory.

3. Therefore, according to the needs of users, choose the processor that suits them. Of course, the processing power of a mobile phone is not only related to the CPU, but also related to memory, storage, read speed, etc.

The true octa-core is generally MediaTek's CPU, the quad-core generally has Qualcomm CPU, Samsung CPU, Apple CPU, etc., the true octa-core is just a marketing selling point, the performance is far worse than the CPU of the three giants, there is no comparison, but ** is also placed there, the cost performance is indeed OK, you can buy a true octa-core mobile phone for a few hundred. The core of the mobile phone is not more powerful, it depends on which one, as well as the production process, the supported network, the speed of operation, etc., in addition, the larger the resolution of the mobile phone, the better the display effect, if there are two ** comparable mobile phones, then you must choose a mobile phone with a high resolution, it looks clear and comfortable, and the power consumption of the inch screen is not very powerful, because they have made the capacity of the mobile phone battery larger, and it can support playing the mobile phone for a long time! A little experience of my own, I hope it can help you!
