AMD vs. NVIDIA: Which Is The Best Choice?

NVIDIA is good for the high-end market and AMD is a more budget-friendly choice for the entry-level and mid-range market.

It’s crucial to know that there are only two leading manufacturers that make graphics cards. They license other companies, including MSI, ASUS, EVGA, and more, to sell their GPUs.

Both companies have different software, cooling solutions, and clock rates on their cards. However, the main question is this: which company makes the best GPUs?

Well, both companies have their ins and outs. Both companies offer several different series of graphics cards. For some graphics card series, NVIDIA provides better performance and price while on other tiers, it might be AMD offering you excellent options.

AMD is renowned for offering affordable and upper-midrange graphics cards. Their latest AMD Navi RX 5000 series cards are giving NVIDIA fierce competition on the power usage front. However, when it comes to high-end powerful graphics cards, NVIDIA is leading the front. Perhaps this is why their top-end RTX cards are high in demand and considered the best graphics cards in 2020.

The Types Of Games That You Play

Battlefield 5 is a very popular FPS game, but it also requires a very powerful graphics card.

The type of game that you play is another crucial factor that will determine the kind of graphics card you should buy. If you play GPU intensive games, you will need to invest in a robust graphics card.

PUBG, Far Cry 5, Project Cars 2, Metro Exodus, Battlefield 5, and Grand Theft Auto V,  are some of the more GPU-intensive games.  If you don’t play many GPU-intensive PC games, you can save a lot of money by choosing an affordable entry-level graphics card.

Your Display’s Resolution

It’s essential to know what resolution that you will be playing your games at. Remember, the higher your monitor’s resolution is, the harder your graphics processing unit will have to work. 

In the simplest words, PC games become more demanding at higher resolutions. So, if you have a 4K monitor, you will need a high-end graphics card.

Your Monitor’s Refresh Rate

60Hz vs 144Hz
144Hz requires much more power than 60Hz because your GPU must pump out a lot more frames per second

Similar to resolution, you also need to think about the refresh rate of your monitor. For those who don’t know, a refresh rate is counted as the number of times your monitor updates with new images per second. For instance, a 60Hz refresh rate means your monitor updates its picture 60 times per second. 

If your monitor has a high refresh rate, you need a potent graphics card to fulfill your monitor’s demand.

Compatibility With Your Power Supply

When buying a graphics card for your gaming PC, you need to check its compatibility with your power supply as well. Since graphics cards need more power than other components in your PC, choose a power supply that can handle it easily.

Additionally, check the compatibility of your card with the motherboard, RAM, and other significant components of your computer.


We’ve now explained the most important factors that you should consider when buying graphics cards for your gaming PC. Hopefully, these tips will help you choose the right card.
