The console games and smartphone games have become very popular in the recent times.  Although, PC gaming still stands the test of time as there is an army of millions of PC gamers across the globe.

The kind of experience that you can expect from a PC is unmatched, and unlike gaming consoles, you only need to upgrade your graphics card, most of the time, if you want to play games that demand a lot of power and memory.

Every PC gamer understands the importance of graphics cards. GPU (Graphics Processing Unit) drives the performance of games that you install on your system. As the gaming technologies continue to advance every year, GPUs need upgradations more frequently than the CPUs.

What Is A Graphics Card And How Does It Work?

The images that we see on the screen are made of tiny squares called pixels. A screen displays over a million pixels at a time, and the system has to decide what to do with each one. The screen uses a translator to convert binary data from the CPU and turns it into graphics that change continuously. The graphics card is responsible for the translations and rendering images on the screen.

The graphics card job is complicated to understand, but it is easy to look at its different parts to understand how it works.  Generating constantly changing images from the binary data such as in high-end video games is a highly demanding process.

Graphics cards first create wireframes out of straight lines to create 3D images. After that, they rasterize the images and fill in the rest of the pixels. The PC goes through this process about sixty times in a minute to generate constantly changing graphics. It continues to readjust the lighting, texture, and color with every changing frame.

A GPU works with the following components of the system:

Motherboard

Motherboard

For connection with other components and power.

– CPU

For data to render images using the pixels.

– Memory

To store information about each pixel and images being rendered.

– Monitor

GPU is connected to the Monitor so that the user can see the images and interact with the computer accordingly.

Difference Between GPUs and CPU

CPU(Central Processing Unit) is called the brain of the computer. The brain of the PC is supported by another brain(GPU) which has a specialized role, i.e., rendering graphics. CPU and GPU work together to deliver the best performance to the user.

GPU’s accomplish many multimedia tasks such as acceleration of flash videos, virus pattern matching, image recognition, transcoding videos, etc.

CPUs are the main processing units of the PC, but GPUs are installed to support the CPU and play a limited role highly efficiently. CPUs are responsible for all the computation that goes on your system. GPUs are also the processing unit, but they are responsible for processing the graphics operations only.

 Why Do You Need To Buy A Graphic Card?

Every computer needs a GPU for the output of the images on display. Motherboards come equipped with the GPUs, and they don’t need a lot of power to run. However, integrated GPUs are not powerful enough to meet the demands of the system that runs graphic-intense games or do other graphic intense work.

Dedicated GPUs

– Dedicated GPUs

Dedicated GPUs are built to deliver the performance that you cannot expect from the built-in GPUs. Graphics card comes with a dedicated memory as well which is used only for performing the tasks related to graphics. Dedicated graphics cards also offer more options for the video ports than a built-in GPU.

High-end GPUs also come with inbuilt-fans to cool the system down as increased power translates to greater heat generation.

You don’t need a dedicated GPU for basic processes like office documents, sending emails, opening pdfs, etc. The most important question that you need to ask yourself is whether your GPU can handle the graphics-centered games and apps that you want to install on your system.

If you want to play the latest top-tier title and want it to run butter-smooth, you will need a dedicated GPU. Non-gamers too need the dedicated GPU for graphics intense applications such as Adobe Illustrate or Fireworks, Maya, etc. There is another scenario in which you will need a dedicated GPU. If you want to power many monitors from the same system, such as your shop, a dedicated GPU will take the load of rendering the images to all the displays. Built-in GPU might not be able to handle the load of multiple displays.

Before you go ahead and purchase a graphics card, you must understand the purpose and also look at the configuration of your system other than the GPU. It makes no sense to install a powerful graphics card on a ten-year-old computer.

How To Choose The Best Graphic Card For You?

You need to take into consideration the following aspects before you go ahead and purchase a graphics card.

– Compatability

Make sure that the graphics card you want to buy is compatible with your system. Look at the size of the card, the power source, system requirements and other things before considering it.

– Requirements

Before you start looking at the processor cores, model numbers, technologies, statistics, etc., understand your requirements. Just check whether the graphics card will be able to perform the task you want or not. For instance, if you want to purchase the graphics card to play Final Fantasy XV or PES18, check the system requirements for these games and see if the graphics card fulfills the requirements or not.

– RAM

When you purchase a graphics card, you should never ignore the RAM. How much RAM does the graphics card has to work with? The Video RAM of your graphics card is separate from your system RAM, and it is used only to perform the tasks assigned to your GPU. Higher RAM delivers smooth performance.

– ‘Reference’ and ‘Non-Reference’ Cards

You need to understand the difference between the Reference and Non-Reference coolers. Manufacturers, such as NVidia, AMD, sell their cards directly to consumers, but they also sell their cards to other companies that modify them and sell to the customers. Cards directly from the manufacturers are called ‘Reference, ‘ and modified cards are called ‘Non-reference.’

The modifiers often alter the cooling systems of the cards. Non-reference cards often have more than two fans mounted. Though they are more efficient at dissipating the heat away from the graphics card, they increase the load on your computer’s cooling system. Non-reference cards are also quieter, but you need to ensure that your computer’s cooling system is good enough to handle the extra heat.

– Budget

Top performance costs the highest. You need to understand how much money you are willing to spend on the graphics card. You don’t necessarily need to purchase the most expensive card, but you must ensure that the card does the job for you and you don’t need to upgrade it too soon.
