What Should I look for in the Best Graphics Card for PC in 2021?

Graphics Card

A graphics card has grown beyond just rendering images on the screen to possessing a powerful processor onboard. It’s the reason you’ll observe a graphics card known as the GPU, or which stands for Graphical Processing Unit.

Choose a Graphics Card in 5 Steps:

There are numerous techniques that can make a fantastic graphics card. Knowing how they work will allow you to select the right card for your needs.

Manufacturers such as ASUS, Gigabyte, and EVGA create their own version of graphics cards. They differ from one another in regards to their types of memory, speed, capacity as well as the heatsinks they use.

Each of these cards is powered by NVidia or AMD GPUs. The GPU is the one responsible for all math calculations required to create the images you see on your monitor and it is the engine that is the basis of your graphics experience.

Do you require a separate graphics card? The processor you’ve selected includes a GPU inside the processor and all on one chip. Intel calls this integrated graphics, and AMD calls it the APU (Accelerated Processing Unit). They are great for PCs that are budget or business-oriented that require only HD videos and for general computer usage.

Step 1: Check out the GPU first, and then the brand

The current range of NVidia’s GeForce 700 and 900 Series as well as AMD’s Radeon R7 and Radeon R9 series are an excellent start to choosing the right GPU. The higher numbers of models such as GT 720 and GTX 950 (NVidia) or 360 and 390 (AMD) show more modern used GPU for sale.

AMD’s Radeon R7 and Radeon R9 series as well as the NVidia GeForce 700 series and the 900 series are the best places to start in your search for graphics cards.

Also, look for the clock speed of the GPU Simply put. More numbers indicate how the GPU is quicker at math. Precisely what you’re looking for when drawing pictures on your screen.

The series and model of GPU you select will depend on the purpose for which you intend to use it and the amount of your spending budget.

Step 2: Compare Memory Types, Clock Speeds, and Bit Rates


Data waiting to be processed by GPU is stored on the graphic card’s memory chips that are specifically designed for it, which are known as GDDR3 or GDDR5. These chips operate with a higher clock speed compared to the normal desktop memory.

GDDR5 is faster and more modern than GDDR3 due to its ability to transfer more data faster using the used GPU India. Data can be transferred up to four times per cycle. So in order to create numbers that appear bigger, manufacturers list clock speeds at 4x the actual speed of the clock.

For instance, the graphic card I’ll use for this build is its 2 GB EVGA NVidia GT 740 card. Advertised as having an internal clock speed of 5500 milliseconds (sometimes described as the effective rate of clocking). Actual clock speeds are 1250 MHz (5000 MHz / 4) regardless of the number you choose to use to compare the graphics cards, ensuring you’re using the same amount.

The more memory you have is good, but more bandwidth is more beneficial. Bandwidth is the quantity of data the GPU can access through the memory bus. It is described as the rate of the memory of the graphic card. The standard rates are 64 bits and 128 bits, however, high-end cards offer more bit rates.

In short, it is important to consider the memory capacity of the card is vital. But you should also consider the model (GDDR3 or GDDR5) and the memory clock speed as well as its memory bit rate (bandwidth which is higher)

Step 3. Pay attention to the amount of CUDA Cores (NVidia) and Shaders (AMD)


The GPU must figure on how it can shade 3D objects displayed on the screen to demonstrate. How light affects the objects to make them appear as realistic as is possible. While NVidia AMD and AMD have distinct names for their respective technologies, they are essentially similar processing tasks.

The greater the amount of CUDA shaders or cores, the more efficient the GPU in rendering stunning images. This is especially crucial for games with frames-per-second (FPS) are crucial or graphics-intensive applications that require graphics.

Are you in the Frame? Think of your most loved cartoon. The pictures are created individually, with minor variations between each one (a frame) and then these frames are assembled with speed. This tricks your eyes into thinking that you’re seeing images that are moving or animated cartoons. If we reduce the speed your eyes will notice a lag between the moving images. Graphics cards function similarly to graphics cards when it comes to documents. The moving images don’t change, but in games, the speed at which the moving images move (the frame rate) is vital.

Step 4: Look for cooler TDP values


Like the CPU The GPU generates heat through every single operation it performs. And this is shown by its TDP value. These values indicate how much power is required to maintain the GPU at a comfortable temperature. Therefore, the greater the power requirement, the higher the heat that the GPU produces.

Find the ones with low TDP values, so that you have fewer cooling and fan systems that are needed. Which not only does this cost more but also makes your computer noisier.


Step 5: Verify the port and compatibility on the card.

Graphics cards are inserted into the motherboard’s PCI Express (PCIe) slots that communicate with the bus of your motherboard (data channels) at various speeds. Based upon the type of slot (2.0 or 3.0) and the size of the slot (x8 or more, x16 or x16).

Be sure to have at least one of these slots on your motherboard. And that they have the PCIe version that is the largest and size of your card.

Also, ensure that the power supply you are using has an extra and appropriate power connector to power the graphic card. Checking your card’s dimensions to ensure it is able to fit into your computer case can help make sure that the card is not ordered incorrectly.

Also, make sure to check your ports (HDMI as well as DVI) within the device. The resolutions that can be supported, as well as how many monitors are able to be connected simultaneously.
