What is GPU? Function and how to distinguish GPU from CPU

GPU card is known as a famous line of cards specializing in handling graphics-related tasks on computers, phones,… So let’s find out in detail what a GPU card is and how to distinguish it. GPU card with CPU okay!

What is GPU?

GPU (Graphics Processing Unit) is a specialized processing card for graphics-related things, which is popularly used in the design field. Therefore, the GPU is used to help process 3D graphics with large amounts of data.

Born with a distinct nature, the GPU cores consist of tens to hundreds of ALU cores supporting users to process thousands of numbers at the same time.

The GPU is also limited in heat and power because the GPU clock speed is lower than the CPU speed by a few hundred MHz or low GHz.

GPU Functions

The introduction of the GPU helps improve the functions that the CPU cannot do while saving time to process tasks. Not only maximum support for difficult graphics tasks, GPU also helps users play 3D games smoothly and architecture-related software works more stably.

Graphics are getting sharper and sharper thanks to rendering technology in cooperation with GPU, providing extreme video and image processing capabilities. The division of different subcores to process images in the triangle area helps the GPU to process quickly.

Real-world applications of GPUs

In-game apps

Players will feel smoother and faster, and the images are vivid and realistic thanks to the GPU. High performance game series such as: Lol, PUBG or Call of Duty, .. all need support from GPU.

PUBG also needs support from the GPU

Applications in graphics

Graphics are the strength of GPU cards, especially images and videos. The Cuda core helps to receive and process information in high-quality video editing such as 2K or 4K. Users will no longer see lag and get enhanced effects because the GPU helps you handle that.

GPU has very high application in graphics

Applications in life

Supporting many applications in life is the next advantage that this card brings. Some fields such as: financial description, electronics, medicine, scientific research, oil and gas exploration, … have integrated GPU to handle work.

This line of cards also meets many different applications in life

Differentiate GPU and CPU

Alike

The CPU and GPU both have single cores that handle certain tasks that the processor needs to do thanks to transistors. In addition, the two processors share the same instruction decoder and buffers, memory access (load/store) handlers, and logic and arithmetic unit (ALU – Arithmetic logic unit).

Memory access handlers are what CPUs and GPUs have in common

Different

The main task of the GPU is to solve graphics-intensive tasks and is capable of processing information sources in parallel. The CPU is the central processing unit / central processing unit that helps to analyze and process all computer data.

CPU has a broader use than GPU

Can CPUs replace GPUs?

A computer needs to handle a lot of different tasks, but the GPU only owns a certain function of graphics processing. Therefore, the GPU is not yet capable of replacing the CPU. In contrast, the CPU is completely capable of taking on the task of the GPU.

Many famous brands are developing models with integrated CPUs with complex image and graphics processing functions. With such great functions, the accompanying price of those machines is also very expensive.

In the future, it is very likely that CPU will replace GPU

How to choose the right GPU for your computer

Motherboard requires PCI-e x16 . slot

The GPU is at its most powerful on a computer when the motherboard has a PCI-e x16 slot, which is the connector most manufacturers design for GPUs. Therefore, when choosing a GPU for a computer, users need to pay attention to this issue to choose the right GPU.

Users need to choose models with motherboards with PCI-e x16″ slots

Dimensions of the length of the GPU

In addition to paying attention to the motherboard, the length of the GPU is the second note that users should learn when buying a GPU. To be able to fully meet the purposes and needs during use, you should check and choose the size of the GPU that is compatible with your computer.

The length of the GPU helps users choose the right GPU for their machine

Power level supported by GPU

The user must ensure that the power supply of the connected GPU is compatible with the computer. Computer power from 300W – 400W for low-end GPU, computer power from 400W – 500W for mid-range GPU and computer power from 700W exclusively for GPU configurations of AMD and NVIDIA .

Depending on different power sources, the level of power that the GPU supports will also be different
