RAM's biggest impact on mobile applications

The main role of RAM is to temporarily store data from computer devices. Generally speaking, the larger the RAM capacity, the faster it can run more applications at the same time.

It should be noted that there are many differences between the operating systems on smart phones and desktop systems. For example, Apple’s iOS currently uses multitasking as long as it has an iOS device with 2GB of RAM. Of course, its multitasking capabilities are very basic and simplified compared to Windows.

For smart phones, the more significant meaning of large-capacity RAM may lie in the ability to store back-end application processes. Each application can maintain its current usage progress without being completely logged out, without being forcibly shut down by the task manager.

How much RAM is enough?

Because Android's system architecture requires a large amount of RAM, the current 4GB has become the mainstream configuration of high-end flagships, and even 6GB RAM mobile phones have emerged, such as one plus three. But even so, Android is not a desktop-class Wndows 10, and you can't open 70 browser windows at once. Obviously, 2GB RAM and 4GB RAM Android phones, the speed difference is still more obvious, 2GB is obviously an entry standard.

So, is a plus 3 6GB RAM useful? Trusted Reviews Editor conducted a test, found that one plus three basically only use about 3-3.3GB of RAM, even if installing more applications, and running in the background at the same time, it only requires 4.3GB RAM, and the use of intensity of general users Basically not reached.

However, after one plus three uses more than 4 GB of RAM, some applications may be forced to suspend. This may be due to the fact that the remaining 2 GB of RAM is actually reserved for emergency use. Therefore, for Android phones, more efficient RAM management is more necessary and blindly increasing RAM capacity is not necessary.

LPDD4 and Dual Channel RAM

As we mentioned earlier, the quality of RAM depends not only on capacity, but also on criteria, frequency, bandwidth, and other factors. At present, most mobile phones use LPDDR3 with a clock frequency of 800MHz and 12.8GB/s. Samsung has taken the lead in S6 and S7 with an LPDDR4 bandwidth of 1552MHz and a bandwidth of 24.8GB/s. The operating voltage has also dropped. Obviously, the standard of mobile RAM is also moving from simple capacity standards to more advanced technical standards.

In addition, the dual-channel function can not be ignored. The company has already implemented it on the PC. It has two channels of the same size and size of RAM to realize more efficient transmission efficiency. In theory, two LPGB4 RAMs with 2GB RAM make up a dual channel, which is more efficient than a single 4GB LPDDR4 RAM.

Finally, the support of the system is obviously necessary. For Apple, the attitude toward iOS has always been more focused on single-threaded processing. Even if the iPad Pro supports multi-window mode, it is not truly multi-tasking. It is reported that this year's iPhone 7 series may be equipped with 3GB RAM to improve overall performance. As for Android 7.0, an eye-catching new feature for split-screen multitasking will be the basic functionality of the system, or the requirements for many RAM capacities will be even higher. In other words, 6GB RAM may not be necessary for Android phones at present, but may become the future standard, and LPDD4 and dual-channel, will become the choice of high-end models.
