After tablets retain some of the computer's features, due to their portability, more and more people are purchasing and using them, and some are pursuing their efficiency as productivity notes; Some people pursue that mobile phones cannot provide a better audio-visual experience. So, what parameters should we see when choosing?

1、 Cpu

The processors of tablet computers and mobile phones, like the Cpu of mobile phones, integrate the CPU, GPU, NPU, ISP, and others on a single chip, which is different from computers.

CPU: Central processing unit, chip brain, responsible for processing and coordinating various tasks.

GPU: A graphics processing unit used for processing graphics related calculations, similar to a graphics card in a computer.

NPU: Neural network Cpu, skilled in processing large amounts of multimedia data such as videos and images.

ISP: Processing image signals is a key component of image processing, affecting photography and shooting.

2、 After understanding the composition of Cpu, there are several points to note:

1. Process technology

The lower the process technology, the more transistors per unit area, and the higher the performance. The current minimum process is 5nm.

2. Multi core

We often hear about several cores, which actually refers to the integration of multiple complete computing engines (cores) in a single core Cpu. Cpu is divided into one super core, three large cores, and four small cores, each fulfilling their own responsibilities. If you need to perform simple tasks, let the small kernel handle them, let the difficult tasks be handled by the large kernel, and complete multiple tasks together.

So the more cores, the stronger the performance? Actually, it's not. We cannot simply look at performance based on the number of cores.

3. Main frequency

The main frequency refers to the clock frequency of the CPU core during operation, which refers to the frequency of the ultra large core, i.e. 2.84GHz. It does not refer to the CPU running speed, but has a significant impact on the running speed. In addition, the running speed of the CPU is not the latest. The main frequency of the CPU must be higher than that of the previous generation, because for tablets or phones, sometimes it has many tasks working together and does not require a high frequency of a single core. The higher the frequency, the greater the heat, resulting in a decrease in frequency.

4. Running points

Whether it's a mobile phone, tablet, or computer, there are various types of GPUs, usually single core, multi core, or GPU. Of course, this type of GPU is influenced by factors such as device, environment, and GPU software.
