5.LCD display with 3 subpixels per pixels
Xiaomi Redmi Note 4X
Xiaomi Redmi Note 8
The device has an LCD display with 3 subpixels per pixel, resulting in sharp and crisp images. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.
6.has an IPS screen
Xiaomi Redmi Note 4X
Xiaomi Redmi Note 8
IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of conventional twisted nematic TFT displays: limited viewing angles and low-quality color reproduction. PLS (Plane-to-Line Switching) is a type of IPS screen developed by Samsung, with increased brightness and lower production costs.

Performance

2 x 2.1GHz & 4 x 1.85GHz & 4 x 1.4GHz (MediaTek Helio X20)

4 x 2GHz & 4 x 1.8GHz (Qualcomm Snapdragon 665)

The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
2.RAM

4GB

6GB

Random-access memory (RAM) is a form of volatile memory used to store working data and machine code currently in use. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing.

The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.
6.semiconductor size
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

Cameras

1.megapixels (main camera)

13MP

48MP & 8MP & 2MP & 2MP

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
2.megapixels (front camera)
