In the past few years when smart TVs had just emerged, major TV manufacturers launched an "arms war". The concepts of nuclear warfare, nuclear explosion and so on continued to emerge. Their focus was on the number of smart TVs. From the very beginning, dual-core From the quad-core to the 8-core, the 10-core, and the 200-core, I feel that this value is still out of control. I can suddenly be replaced by hot words such as ultra-thin, curved, and OLED. "Competing" just ended.
Indeed, as televisions become more intelligent, screen size/sharpness is no longer the only standard for which we choose to buy televisions, and hardware performance and functionality will also be the focus of many people’s considerations. Let’s talk about how to pass The hardware parameters of the chip to select the smart TV.
First, look at the heart, CPU CPU. With the increasingly complex functions of smart TV systems and more and more applications, the requirements for chip computing performance are also increasing. The performance of the chip depends on the number of CPU cores and the frequency of operation. This will affect the smooth running of the UI system and various applications and games. In smart phones, quad-core and eight-core are common, and TVs cannot lag behind.
Currently, the Cortex-A17 and Cortex-A53 have become mainstream, and the use of Cortex-A7 and Cortex-A9 TVs is somewhat worrying. Although the fluency of the UI can be guaranteed by simplifying system functions, smart applications in the future may be Can't run smoothly. Especially in the 4K era, the requirements for computing performance are even higher.
Second, GPU, graphics "brain". The GPU's role is similar to that of a computer's graphics card, except that the TV does not have a discrete graphics card. The GPU and CPU are integrated on one chip. The GPU is mainly responsible for the graphics rendering work, which is especially important for the game, and requires a strong GPU and CPU to provide a smooth gaming experience.
If you want to play 3D games, you need to have a strong GPU, because in 3D mode, the workload of GPU rendering graphics will double, and if the performance is not enough, it is easy to get stuck in the picture.
Currently, there are several GPU models in smart TVs, such as PowerVR SGX series and ARM Mali series.
Third, RAM runs memory and is as important as blood vessels. Running memory is relatively simple, mainly depends on the size of the capacity, many old smart TV menu response is very slow, often crashes, one of the main reasons is the memory is too small. Today's Android 5.0 and above systems are increasingly demanding on content, and mobile phones with 1GB of memory are very slow, not to mention smart TVs, so 2GB is the most basic requirement. Recently, some enterprises have also proposed to fully enter the 3G era. One of the 3Gs refers to RAM operation memory.
The next question is the focus of our day: "Why are some smart TV hardware configurations already top-notch, but can TVs use cards more and more slowly?" Let's take a look at "cards." What are the basic reasons?
Question one: More and more applications are greedy
The red-shirted governor, Zhou Hongyi, has also recently been gambling on greed. No matter how much memory it runs, it will still be slowed by them. This is about unscrupulous application developers. They will populate a large number of advertisements in APPs. There are many ways to implant them. SDKs also have APIs, because they can earn a lot of money by inserting advertisements.
Speaking of the ad's implantation, some large apps will require users to bind and install other apps when they download and install. We really hate it. Sometimes an app finds an update, but when the user finishes updating, it is likely that there will be a new icon on the desktop. Imagine how much this APP is installed. How could your smart TV not be carded?
Question two: nuclear more, not smooth and noisy
It is thought that many cores will not get stuck, and often such users will complain that "Why the ten cores will still be stuck!" In fact, the fluency of the system is not related to a few cores. What we call fluency includes two parts:
First, the fluency of the system itself is actually the fluency of the “starter†application. Second, the fluency of the application is the fluency of various applications.
It is not the core that affects these two fluency, but the single-core performance and memory bandwidth. Our "initiators" and various applications can only use one or two cores in most cases. Few can use four cores and can use the eight cores. Therefore, there are not a few cores that determine the speed, but how single-core performance is!
Question 3: RAM is still important
Is the larger RAM capacity, the faster the smart TV will run? In fact, this issue has always been a problem tangled up with many students. The speed of smart TVs in the Android system is fast, RAM is not the only one that affects the speed of smart TVs, and more is determined by the coordinated processing of the CPU, GPU, RAM, and ROM. With the strong GPU processing capability, RAM idleness greater than the system's minimum residual value, and less garbage debris files in the ROM, these points are achieved, and the smart TV's operating speed is faster.
How many programs can a general 1GB of RAM open, and what is the essential difference between it and 2GB of RAM? The specific number of applications that can be opened is not specifically calculated because each person's software is different and the memory used is more different. Android system has a system adjustment rule, such as some smart TV settings, the system is less than 21MB of RAM, you can not support the smooth operation of the system, so there will be Caton, and even forced to close some of the programs. For 1GB and 2GB RAM models, if the CPU, GPU, ROM, etc. are all the same, mainly in large-scale applications, 2GB of RAM is more advantageous in large-scale games. And 1GB will appear slightly, or forced to close.
Well, when it comes to this, I believe that netizens have a certain understanding of the hardware and fluency of the smart TV. You also want to know what the truth of the home appliance is. We would like to inform you that we will answer your questions.
