8GB is here. Does the mobile phone really need such a large storage？
With the continuous improvement of the upgrading speed, the mobile phone configuration is also constantly refreshing the record. Ten-core processors and 4K screens have already appeared, and even the running memory has been upgraded to 6GB last year. At this year’s CES 2017, let’s see the debut of the first 8GB running memory mobile phone. In the past, 4GB was called Little Monster Level, so what is the concept of 8GB now? Today we will talk about 10 things about the running memory of mobile phones.
8GB is here. Does the mobile phone really need such a large storage?
1、How is the 8GB mobile phone stored? "come"?
There are many factors for the development of mobile phone running memory, the most important of which is the support of mobile phone SoC for mobile phone running memory. When the 64-bit processor began to be used, the smart phone officially announced that it had entered the era of 4GB running memory. With the advent of Qualcomm Xiaolong 820 processor, it supports up to 6GB of running memory, while Qualcomm Snapdragon 821 processor supports 8GB of running memory, and Samsung officially mass-produced 8GB of RAM particles. Hardware conditions allow, and 8 GB of running memory will naturally come.
2、What exactly is the running memory of a mobile phone?
Dream is the first Android phone with 192MB of running memory.
If memory is mentioned, the first thing that users should think of is storage memory. When buying a mobile phone, they will first ask how big the memory is and how many "things (APP//blockbusters)" they can hold. Generally, the size of running memory is not asked. Running memory refers to the memory when the mobile phone runs the program, also called RAM (referred to as transport memory). In short, in theory, the larger the running memory of the mobile phone, the smoother the system runs.
3、Will the memory conference not have the problem of "excess" like the processor?
The first mobile phone with 1GB running memory-Samsung Galaxy SII
The running memory of a mobile phone is not like a processor. In a sense, there will be no "excess" problem, because as long as you open more applications, how much running memory will be filled, so there is no such problem as the processor.
4、How much storage does Android phone take up in daily use now?
Mobile phone system and daily multitasking occupy a lot of running memory.
Since the first release of Android Beta in 2007, after nearly ten years of continuous evolution and upgrading, the system has occupied more and more memory. From the original 1.0 native system only occupied 100M of memory, to the present 7.0 system occupied nearly 2GB of memory, plus various apps used daily, taking a 4GB mobile phone as an example, there may usually be only more than 1GB of running memory left.
5、Why is the Android phone stuck when it is used?
LG Optimus II is the first mobile phone with 2GB of memory.
"Caton" has always been a pain point that Android mobile phone users have to face. Speaking of the Android system, the mobile phone is stuck. In fact, this has a great reason with the mechanism of Android. Android and iOS are very different when dealing with garbage collection. Android’s garbage collection mechanism needs extra memory for garbage collection. When an Android application ends running, the mechanism needs more memory than it to recover the memory occupied by the application. In addition, more and more mobile phone programs are installed, the function of mobile phone APP is becoming more and more powerful, and the demand for ROM and RAM is becoming more and more powerful. Over time, mobile phones begin to get stuck.
6、How to clean up the special garbage of Android and iOS phones?
Samsung Galaxy Note 3, the first smartphone with 3GB of memory.
The special garbage collection mechanism of Android phone is similar to the eraser principle. A piece of white paper is full of dirt, and the eraser is erased word by word. The advantage is to accurately remove the dirt and keep the content needed on the paper. The disadvantage is that the recycling mechanism is slow to process. Once a large number of different Android applications run, the problem will follow. If the memory of Android phone is not enough to call this mechanism, the running speed will slow down. IOS has done a lot better in this respect, tearing off the dirty paper and opening a new page, which is fast, but when users switch back to these applications, they will experience the waiting process of restarting.
7、With a large amount of storage, Android phones will run faster?
The first smartphone with 4GB of running memory-
If the processor of Android phone has strong performance (speed up processing) and large memory capacity, it will have a unique advantage. It can ensure a large number of simultaneous operations, and the large memory capacity is convenient for the "Android garbage collection mechanism" to call memory, so that the system can maintain a relatively smooth state. And the user switches back to the previous application and remains in the last intact state.
8、What is the relationship between GPU performance and running memory?
Mobile phone GPU operation occupies running memory space.
Different from PC, smart phones often don’t have independent graphics cards, because the size and heat dissipation of mobile phones are limited. In other words, the GPU of the mobile phone also needs to call the running memory, so it is necessary to increase the capacity appropriately. At the same time, with the improvement of screen resolution, demand, and even popular virtual reality applications, mobile phones are required to have better graphics capabilities. In addition to the performance improvement of GPU, the larger the running memory, the better the performance of GPU.
9、Is it really necessary to equip a mobile phone with 8GB of running memory?
The first smartphone running 6GB of memory-
With the continuous expansion of smart phone functions, the volume of systems and applications will become larger and larger. More and more systems and applications will force mobile phone manufacturers to constantly upgrade their memory, which is a process of mutual promotion and spiral rise. Simply put, when 6GB is widely used, the demand for memory of systems and software will be further improved, and it is very necessary to store 6GB at this time. The same is true when 8GB of running memory arrives.
10. What is the relationship between the standard of LPDDR and running memory?
Development process of mobile phone memory standard
LPDDR is a kind of DDR SDRAM, which is a communication standard for low-power memory formulated by JEDEC solid-state technology association of the United States. In short, mobile phone memory particles are calibrated by this standard. The LPDDR RAM used in mobile phones is the abbreviation of "low power consumption double data rate memory", while the current LPDDR R4 for mobile platforms can bring equivalent performance (speed) and take into account less energy consumption. In addition, compared with the previous generation standard LPDDR4, two new features are double data rate and low power consumption; That is to say, the speed of speaking is 50% faster and the power consumption is low.
Write it at the end
In order to meet consumers’ pursuit of performance and the continuous expansion of mobile phone functions, mobile phone manufacturers have been upgrading processors and improving running memory. The memory of a mobile phone is like a driveway on a highway. The more and wider the driveway, the smoother it will be to drive, so the greater the operation of a smart phone, the smoother it will be to use. In addition, it should be noted that when you buy a mobile phone, you should not blindly pursue the absolute size of running memory, but also look at the remaining space under normal use of the mobile phone.
