What parameters do I need to look at when buying a tablet?

After the tablet retains some of the functions of the computer, more and more people buy and use it due to its portability, and some people pursue its efficiency as a productivity note; Some people who pursue mobile phones do not bring a better audiovisual experience. So, what parameters should we see when choosing?

One, CPU

The processor of tablet computers and mobile phones is the same as mobile phone CPUs, which integrate CPU, GPU, NPU, IPP and others on a single chip, which is different from computers.

CPU: The central processing unit, the chip brain, is responsible for processing and coordinating various tasks.

GPU: The graphics processing unit is used to process graphics-related calculations, similar to the graphics card in a computer.

NPU: Neural network CPU, good at processing a large amount of multimedia data such as videos and images.

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

Second, after understanding the composition of the CPU, there are still a few points to pay attention to:

1. Process technology

The lower the process, the higher the total number of 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 a core CPU integrating multiple complete computing engines (cores). The CPU is divided into one super-large core, three large cores, and four small cores, and everyone performs their duties. If you need to perform simple tasks, let the small core handle it, and let the big core handle the difficult task, and multiple tasks are completed together.

So the more cores, the stronger the performance? Actually, no, you can't simply look at the performance in terms of the number of cores.
