Modern laptops, pcs, and tablets have graphics cards. This is because graphics processing is required by most applications.

A discrete graphics card can be added to desktop PCs. These graphics cards may be upgraded and changed in the future.Buy best quality low price Hard disk online in Nigeria Shop all kind of Refurbished IT spare parts online at-Xfurbish

Graphic cards for PC gaming are necessary because most 3d games today require one. The graphics card is also necessary for any other 3D applications like animation and modelling.

Not only specific applications but also standard OSes like Windows and Linux need to have some graphics capability for optimal performance.

Graphics Cards can have many technical specifications that will determine their performance. It is imperative that you evaluate key specs, such as the gpu’s performance and memory requirements.

Although more powerful graphics cards may be cheaper than less expensive ones, that doesn’t mean they are always more cost-effective.

Even if you have an expensive budget, it is important that you ensure that the graphics card’s processing power is worth the price.

We’ll be covering the essential features and specs for graphics cards in this article.

Compute Performance – TFLOPS

Nvidia vs Radeon

GPUs are manufactured by Nvidia, AMD and only two brands. They are then used to make graphics cards by third party manufacturers. Both companies offer a vast selection of GPUs, at various price points and with different features. The GPU is sometimes called the graphics processor or the graphics chipset. They both refer to the same thing.

There is a GPU for everything, from basic gaming through high-fps gaming and 3d modelling. Many technologies can be implemented on the gpus under a different codename. Nvidia uses the term CUDACores while AMD refers to them Stream Processors. Similarly AMD uses Crossfire, while NVIDIA uses SLI for multi gpu setups.

Available as discrete pci pc cards for desktops pcs or fully pre-installed inside of laptops, dedicated graphics cards can be purchased. The graphics card can be changed on desktop pcs in order to upgrade to the latest version. However, this may not be possible on laptops.

These GPUs are the most in-demand.


  • Radeon X5600 XT
  • Radeon RX550
  • Radeon RX580 GTS
  • Radeon RX570
  • Radeon RX6800 XT


  1. Geforce GTX1050 Ti
  2. Geforce GTX1650
  3. Geforce GTX1660 Ti
  4. RTX 2080
  5. RTX 3080
  6. RTX3090

GPUs of higher price are generally faster and have more capabilities and functions.

2. Stream Processors/CUDA Cores

These terms are used interchangeably to refer to the identical thing. Stream Processor, the Nvidia hardware nomenclature, is used for AMD hardware. These cores are the computing units found in the GPU which perform the graphics computations. Performance will be higher if there are more cores.

Comparing cores from different manufacturers may not provide an accurate indication of the difference in graphical performance. Many variables affect GPU performance, including clock speed and architecture.

Even within the exact same gpu brand the architecture (the design or procedure upon which a GPU built) can drastically affect the performance cores. The number of cores on two cards made from the same architecture can be compared to give you a better idea.

Example of core numbers for some GPUs

  • AMD Radeon RX5700 – 2304Stream Processors
  • Nvidia GeForce GTX 1650 – 896 CUDA Cores
